and other directional mics?

silk python
#

How directional does it need to be

shadow stag
#

enough to not have speakers bleeding into it

silk python
#

From how far away?

shadow stag
#

1m or less

#

in-desktop distance basically

silk python
#

Then I’d really say you should save up for an interface and a mic then

#

Then I’d say do some more research on mics that are good for music production, cause shotguns are usually for films

#

And are condenser but I think a dynamic mic is better music (correct me if I’m wrong here not sure)

shadow stag
#

ah interesting

#

so it wouldn't really cut it for like streaming/chatting?

shadow stag
silk python
#

Ofc good luck 🤞

shadow stag
#

wouldn't shotguns/something for film work fine for vox/vocals anyway?

I'm looking for some good Monitors to fill my audiophile needs (I need monitors for listening to music making music and video editing) I'm upgrading from my 16in M5 MacBook Pro speakers at one point I tried Bose Companion 20’s but the mac has better speakers than those

does anyone know where I can find information on making a Delta Sigma DAC I want to check if what I have so far designed is going to work before I commit to making it

#

the username goes really hard btw

#

id check the sonic visions discord server for engineering advice, they have the most diy nerds there

sleek lily
#

I could probably help you with some simple questions

#

If you're using a chip, it'll likely be a lot of reading into the information for that chip and designing firmware to interface it

@lean grove yo wsp idk if u remember but u recommended me the topping e2x2 i bought it bro

Sounds like you've got a good idea on what you're doing. Definitely add that project onto your resume if you have room after. It's gonna be a fun project, but it'll also show that you know how to manage a project 👍

That's a good idea thanks

im searching for new in ear (true wireless) earbuds with a budget of around 200 bucks at max, theyd need to have ANC , any recommendations? Im using them for listening to music and workouts

trail solar
#

I don’t know wich phone ecosystem you are on. But if you are on IOS AirPods are one of the most used for a reason. Especially the AirPods Pro 2 are really great. I like their sound better than the sound of the Pro 3. And Sound ist obviously different for everyone, so you would need to have a look wich you like better. The Heartrate Monitor in the Pro 3 is obviously nice for workouts. I’m not sure if you can get them for 200 though. But that shouldn’t be a problem for the Pro 2. At least it isn’t in Germany.

astral urchin
trail solar
#

Yeah, that’s sadly true.

lean grove
#

Regardless of you being on Android

#

Go to a display iPad at Walmart or target, set it up once, and then use them as normal

#

The only thing you're missing would be battery read out but that's not a dealbreaker imo🤷

viscid tangle
#

That's if you're in the US

#

Only a few places have the airpods pro 2 new but they're at $200 and close to the price of getting airpods pro 3. AIrpods pro 3 are overall superior it's just sound that people have mixed opinions on.

#

You can get renewed airpods pro 2 though.

i have a minifuse interface already

#

My default reccs are Se V7, SM58, and XM8500 - Q9U if you want the broadcast style microphone, the closest shotgun microphone to 100 is still like 200 ish in the AT875R. USB mics would be Elgato Wave 1/3

#

Do you have a deeper or higher pitched voice

tired crown
#

id say inbetween

haughty girder
#

Do you have a microphone arm?

tired crown
#

yeah

haughty girder
#

If in-between then SE V7

winged valve

is a yas-107 overkill for desktop speakers

Tried to repair my flip5 today, this thing is the least serviceable piece of tech i've come across, wtf. There are different version of the same model (mine doesn't fit the ifixit guides for example).

Won't buy jbl again. (I know for audiophile jbl is not good anyway apparently)

brisk topaz
#

so i got some truthear gates

#

but they didnt come with a pouch

restive sigil
#

i meanm JBL is mostly for ppl who just want something that plays music, that they can pick up at their local tech shop. i'd never take them serious on any level. in the same league as Bose

lean grove
#

JBL has a decent consumer audio division

zenith pawn
brisk topaz
#

maybe

#

i sent them a support ticket

haughty girder
#

and the issue with bluetooth speakers is you have to realize

#

you're asking for upwards of 100db spl @ 1m from drivers that are absolutely tiny for the task

#

add on water resistance and all the fancy bluetooth features, you end up with a device that's hard to open and repair and must be tightly integrated

#

it's not a JBL thing, it's just a bluetooth speaker thing

#

if you watch LTT video showing them building a bluetooth speaker you'd realize how difficult it is to get big sound from a small chassis

#

Also region specific or even revision changes is not a bad thing.

#

If a product is produced from 2022 - 2024, but in 2023 they made the device last longer through a board revision, that's overall better even if you then have 2 different (but not concurrent) revisions of the same model

vapid plank
#

Jbl is mostly junk but loud

lean grove
#

@vapid plank
If the JBL speakers are junk I'm curious what you consider to be good

vapid plank
lean grove
#

We're talking Bluetooth speakers here

#

Not audiophile stuff. And even then, JBL still has pretty good stuff.

vapid plank
#

If you just want a Loud BT Speaker there fine

There loud

lean grove
#

They're*

vapid plank
#

JbL doesn’t have a home Product worth the cost

#

Least to me

There not my sound profile

#

I don’t only want boom

lean grove
#

Saying you're not a fan is one thing. Saying they're junk is another.

vapid plank
#

I’ve heard there best offerings

For the cost there just junky

If your a fan that’s fine

lean grove
#

And like. I'm still not sure if you're still comparing JBL Bluetooth speakers to Sonos Faber towers

#

You never clarified that

vapid plank
#

I’m not

Jbl Makes home Products

lean grove
#

They make many things

#

Studio, hifi, consumer

#

Professional

chrome imp
#

sometimes you just need a bluetooth speaker for the lake or a campfire, JBL is more than adequate for that

vapid plank
#

Why does my opinion bother you so much

lean grove
vapid plank
#

I can think whatever I want is junk

#

You don’t have to agree

lean grove
#

Why does my opinion of your opinion bother you so much?

If it's free and you like it that's infinite value

#

Anyone know of any good bookshelf speaker stands that could sit on a desk to raise around 20-30 centimeters that arnt like these spring like ones that are kinda shaped like this <

chrome imp
#

it's a loud bluetooth battery speaker that's ip67 rated, mint

lean grove
#

If you can tolerate the size, they're a good option

vapid plank
#

Your local metal shop could likely fab up something for you with scrap pieces

Costs likely aren’t crazy and you get exactly what you want

lean grove
#

Oh yeah I completely forgot about those

#

Those are nice. I had a pair before my speakers stopped fitting on them

chrome imp
#

cheap enough too

#

but yeah the base plates seem a little small

lean grove
#

If you have a flat bottom speaker, they should be fine

Unfortunately for me my speakers have ports on the bottom

should i get edifier mr4 speakers and are they good

yeah pretty good

according to grey

Bigger number better? More common than you'd think

i’ll wait for the mr6 pro maxes then!

haughty girder
#

I'm not saying age is a problem in audio equipment, but it wasn't good when it first game out and it hasn't aged well either

#

Unless you're dead-set on broadcast-style mics, I'd take the SeV7 over it any day

tired crown
cold spindle
#

What would you use it for even. And do you have a interface already.

#

Tho yeah the SeV7 is good for just basic use for voice calling it's goated and sound not bad Vs even higher end mikes like the dpa dfacto

#

Ofc higher end stuff is better tho yeah all depends on what you would use it for for just discord calls the SeV7 is good. They do have some more broadcast looking mics that are also dynamic mics like the dcm6 and dcm3 with the 6 having a phantom powered preamp

oh wow !

thoes look super awesome !

#

how is it ?

thin birch
#

They are super neat. I have 3 of them, but haven't really given them the time of day. That's more on me than it is on them tho.

#

They all seem to operate in relatively the same way, tho, so I think once you get pretty comfortable with one, you can work pretty well with the other models also.

thin birch

Also they link up in series so you can combine them

Henlo, I'm looking into getting my first desktop dac. Currently I'm running ATH-M50X and KZ ZSN Pro and want to maybe get HD600 down the line. Currently looking into the FiiO K11 R2R. Any advice would be appreciated

#

Not sure if it fits here.. can i ask questions about acoustic guitars? They arent tech per say..

shadow stag
#

the creative pebble pro arrived!

shadow stag
#

hey, how im supposed to use usb audio with the pebble pro?

#

i connected it via usb c to a to my display which should passthrough to the computer but windows 7 reports nothing connected to it

#

oh got it

#

it took a moment to detect it

#

is it normal for the pebble pro to distort with usb audio at higher volumes?

#

had settled on like ~50 for normal listening

haughty girder
#

yes

haughty girder
#

most amps can over-drive their drivers

shadow stag
#

ah i see

#

couldn't get it in firmware update mode at all tho :/

#

its just too hard to keep holding

shadow stag
#

at least it has the passive bass reflex thing

#

im feeling slight buyer remorse because of some of the features

elder thistle
haughty girder
#

a 2.5" driver already needs ~300cc (if not more) of space within an enclosure

#

a 4" would be approaching 1000cc (1 Litre) of internal space

#

at which point your speaker needs to be much bigger, with a much more powerful amp, and they're much harder to tune

#

the choice to keep a 2.5" was for the size and cost, because they're cheap and sound good enough

shadow stag
#

why the switch to more amp power is my question

shadow stag
#

also it seems like the final color was going to be alpine green but that never materialized

haughty girder
#

oh sorry 2.25"

#

math comes out to basically the same

haughty girder
#

It's the exact same reason people buy guitar or bass amps at like 500w

shadow stag
#

wtf

haughty girder
#

and recommend 100w for just "small room"

#

not even ha venue

shadow stag
#

specs say: Colors Alpine Green and White

haughty girder
#

most amps will distort well before the amp reaches max wattage

#

but that's what you want

shadow stag
#

interesting

haughty girder
#

because it means the amp will never be the source of distortion, the driver is

shadow stag
#

why not have matching driver and amp?

haughty girder
#

which also means as long as you're under the limits of the driver, you're getting the most out of that driver + it's cleaner because the amp is running well below its limits

shadow stag
#

considering the desktop space i think i seem to be good with the 2.0 pebble

haughty girder
#

you went from pebble 2.0 to pebble pro?

shadow stag
#

no, from genius speakers to pebble pro

haughty girder
#

oh

#

t30?

#

t20?

shadow stag
#

genius sp-u150x

#

much older

haughty girder
#

wait wrong brand kek

#

jesus

#

3.5 watts

#

which means distortion likely closer to 2

shadow stag
haughty girder
#

anyways pebble pro's big selling point is built in DSP

#

on top of a cleaner amp

shadow stag
#

cant access its tuning cuz windows 7

haughty girder
#

why are you running windows 7

shadow stag
#

as i said many times, grandfathered all hdd system

haughty girder
#

is that an M27Q?

shadow stag
#

the monitor? og g24f

haughty girder
#

damn

shadow stag
#

i should probably have bought the g24f 2

haughty girder
shadow stag
#

no space and it has its own slew of issues and dont want to break the customized installation and software. i have installed w10 but its at the end of the drive leading to it being slower than w7

haughty girder
#

.

#

I've been using ssd for so long now I forgot short-stroking was a thing

#

i get it tho

#

with that said

#

I do question the thought of getting speakers before a new pc

shadow stag
#

im not into ssds because of their life issues/shortcomings compared to hdds

#

idk, easier choice than picking pc parts

haughty girder
#

Wdym life issues/shortcomings?

#

the only shortcoming is price

shadow stag
#

things like dying after a year of no use, tbws, paging torture saturating write cache

haughty girder
#

in fact I've had more HDDs fail on my than SSDs in the past 14 years or so

shadow stag
#

surprisingly in the less than 10 but more than 5 years of this set of hdds none has failed

haughty girder
#

dying after a year of no use is very situational - if you live in the sahara desert then just power it on once in a while and it'll be fine. Paging torture saturating write cache makes no sense

shadow stag
#

yeah, i had low writing speeds on win10 with 8gb of ram and hyper-v enabled

haughty girder
#

I've had 1 SSD fail and it was a controller failure on a Kingston A2000, which they replaced for me for free

shadow stag
#

was low on space and also partitioned

#

its a Kingston SUV400S37480G

haughty girder
#

Jesus

#

you bought the cheapest dramless sata ssd

#

and then said that SSD is an issue

shadow stag
#

not me, dad back then

haughty girder
#

dramless is not a big deal now too with nvme since HMB exist

shadow stag
#

¯_(ツ)_/¯

haughty girder
#

but with sata you NEED dram and you need something with a good controller.

shadow stag
#

too late

#

with dram its not as cheap or idk

haughty girder
#

but my point still stands - using a general statement saying SSD is bad because you had the cheapest worst ssd is dishonest at best

#

I had a Patriot Blast 240gb (Sata 3 with dram) and that thing has long outlived several of my WD Greens from that same era

shadow stag
haughty girder
#

why are you running windows 7 when you have a new macbook

#

esp one with hdmi

#

just toss your HDDs into a ZFS or RAID 5 as a storage server and use your macbook damnit

shadow stag
#

cuz its on macos, i also have a mac mini late 2014 with 6 installations of major macos versions in a 1tb poor cheap kingston ssd, the hdd on sierra is a snail and ends up freezing

haughty girder
#

then why did you buy a macos laptop if you don't like macos

shadow stag
#

sighs

#

im a multi-os user but still maining windows due to its ecosystem

#

i'll see if vxkex can get me going for using creative app

haughty girder
#

wnidows... ecosystem...

#

windows doesn't have an ecosystem...

#

in fact windows is probably the most fragmented of any operating system

Anyone have a good solution for sharing an audio signal between 3 different amplifiers in 3 rooms without running wires? I just want to play music throughout my whole house

I'm sure there are other similar products out there (including rolling your own from a Raspberry Pi) - this is just the one **non **SONOS / Bose / Apple one I'm familiar with.

Hmm

Thanks for that
I don't think it's quite what I'm after, but I appreciate it

LMS?

lean grove
#

Lyrion music server

#

If you're tech smart it's gonna be your best option

I dunno, are there raw 2.4ghz tx/rx devices I could just feed audio, or something like the powerline adapters?

#

Also I do have ethernet wired already, could there be an IP device that fits this role?

ive been intoxicated for the last 9 hours

unique wind
#

for me not really it's only a couple of things

#

the only two remaining banes of linux are the lack of support for some OBS plugins, and nvidia gpu performance

zenith pawn
#

what about all your various hardware monitoring tools and stuff for overclocking

#

i guess if i had a list of all the windows programs i used it would be easier

unique wind
#

cpu is all done in bios, and for gpu i could just run stock

zenith pawn
#

it's just tons of tiny little utilities like notepad++

unique wind
#

all that's really keeping me in windows are some obs microphone processing plugins, nvidia gpu performance, and valorant

zenith pawn
#

I wish I remembered, when i switched to linux the first time it was like throwing everything away

#

but maybe windows had less stuff built in at the time

unique wind
#

windows 10 21h2 is still the most plug and play bugfree experience that ive ever had with an OS

#

ive been on W11 24H2 again for two weeks and im already itching to go back

#

ive been trying to accept W11 since 2024 on and off because it performs better in cpu limited gaming, and the UI is prettier, but it's just buggy

#

namely with chromium based programs with hwaccel enabled

zenith pawn
#

sounds like you're getting what's normally supposed to be the linux experience

unique wind
#

microsoft made some window manager changes in 24H2 that have caused some visual artifacts in chromium apps with hwaccel enabled for some users

#

it's widely documented

#

w11 23h2 theoretically works fine, but it loses security update support in a few months

warm scarab
#

fusion 360, adobe software, davinci resolve, tinkercad, solidworks

#

all gone

#

I could spend two hours trying to install davinci resolve onto linux or i could spend 20 minutes debloating win11 and disabling updates

#

whenever you do productivity work you want the productivity to become the outcome rather than trying to troubleshoot your os because vst plugins decided to not work due to some schizoid reason

warm scarab

if you like audio so much why dont you listen to muskc

#

or construction noisrd

winged valve
#

I did not say anything about liking audio

zenith pawn
#

what do you want then

unique wind
#

im still on windows because i dont want to give up gpu performance or obs plugins

warm scarab
#

could go amd

unique wind
#

then id really be giving up performance xD

#

i have a 9800x3d and 5090

warm scarab
#

fair enough

#

what do you need a 5090s performance for anyways

#

even a 15% fps hit should run anything on silly high fps

#

if you had a 3060 and didnt want to lose id get it but what could you possibly be doing with a 5090 where that perf hit is an issue

zenith pawn
#

trick question the performance hit is by using windows instead of cachyos the proclaimed god of performance

warm scarab
#

cant fix it without nvidia wanting to fix it

zenith pawn
#

(cachyos is a Linux distro that constantly gets pushed on people for having performance patches)

warm scarab
#

i know what it is

#

its not that deep its just spiced up steamos based on arch

#

they still need the drivers from nvidia

#

as any other os does

#

and the drivers are shit

#

how can you optimize a os for the gpu to calculate better when all you give it is the graphics task from a game and nothing else

#

answer is nothing

#

anyhow you can just google these results we dont need to be discussing this its all public

Hey guys, I'm in the need for some gaming headphones recommendations in the $100-$150 USD price range. I mention gaming specifically because I would like to have a wireless headset with an inbuilt mic. Many people in forums are recommending some turtle beach headsets and steelseries arctis nova series for this price range.

I am skeptical about the steel series, because I used to have a Arctis 7+ and the left side stopped working completely in a little over 2 years of regular use. They were comfortable to wear but didn't fit my head as well so the audio sounded a little off and I wasn't impressed with their overall sound quality either. So I am not sure if a different Arctis is the right choice.

Any suggestions are appreciated :)

@steel escarp I remember you asked me before here for an example of a claim that requires we understand how far the definition of minimum phase is being stretched.

I recently came across a perfect example, to which I actually made a great analogy for, which I feel makes the issue more understandable.

I had a discussion about how magnitude response is not the same as frequency response. The opposing view made the assumption that we don't need phase because headphones are minimum phase. I made the point that they are not actually minimum phase, and even if they were, phase is still part of frequency response, as minimum phase does not mean ignore phase.

The part where I felt the definition as to how far we stretch it being set becomes important came after. Someone made a very reasonable sounding assumption that we can ignore phase because by a hilbert transform, we can derive phase of a minimum phase system from magnitude response. For a perfect minimum phase system, this is actually true. For the stretched definition, we actually can't. This is why it's important to distinguish "close enough for some simplification" from "actually is so we can mathematically treat it as the rigorous definition".

The example I gave: if I throw a ball and want to know how far it'll fly, it's reasonable enough to assume no friction for simplicity. However, it's not okay for me to assume from my no friction assumption that this means I'm in empty space, so the ball will go forever and there must be no gravity.

It's useful for eq

#

The issue is when you apply that assumption outside that like it's not a simplification, which is very common in audio spaces.

steel escarp
#

Oh yeah... its like not even optional to also fix non minimum phase issues in your room

#

Its more important than DSP

#

Well depends on the frequency tbh

sleek lily
#

Yea, it's a simplification that can be very useful for some applications, but it can't be used to derive things as if it's a rigorous definition

steel escarp
#

Its funny how shifting the phase alters the frequency response a bit. I haven't been able to make my system sound better with it tho.

#

Talking about my speakers

sleek lily
#

Another example I gave was with BJT's. It's fair to say Ic=Ie when performing calculations around them. It'd be absurd to assume that because of this assumption, that's actually just a wire with the same current so vce must be 0, so it's now magically not a bjt and we don't have an amplifier.

One day I'll have a room big enough to house all the acoustic treatment I want. A room is only as good as the amount of treatment it can hold. No other limiting factor.

not really

you'll run into internal resistance issues long anything else happens

#

but I'm just being pedantic.

sleek lily
#

This paper actually does a great job at demonstrating why we shouldn't conflate the assumption that headphones close enough to minimum phase for some purposes with "headphones are minimum phase". The existence of all pass phase alone inherently means they are not minimum phase, and results in some pretty big issues if we try to ignore phase by stretching that simplification to a physical rule.

Should I get the XM5 earbuds now or wait for the Xm6 to release?

lean grove
#

At the very least, the price of last gen stuff will go down.

astral urchin
lean grove
#

If you're worried about price, there are really good non-mainstream stuff for like $50

#

Tws earbuds are a money making machine for most brands because they can charge $300 for a pair and not worry about customers really knowing why they're so expensive because the cheaper stuff isn't sold at Walmart or Best buy.

Low information market = bad competition

astral urchin
#

I paid like 50 bucks for my soundcore liberty 4 NC and theyve been good for a year but im sick of always having bad ANC and now the bass is just horrible so now I kinda want to just spend a little more up to like 200 just to have something thatll last

#

I dont know how good the airpods will be on an android

lean grove
#

But otherwise you don't need to spend $200 to get good bass from an earbud.

#

I would encourage you to look at the moondrop space travel 2's

#

The ANC is not gonna compete with apple. But they're gonna be much better value.

that price range is pretty scattershot for closed backs, depends on what you prefer. I feel like for most people they'll land on either FR1, K371, H200, or DT 270 pro.

#

nice

#

I really hope we can find a way to get MIRE systems in the hands of more people in the coming years. Would be great for stuff like this

elder thistle
#

these seemed to have a lot in common with the 400se

#

they really surpress the louder end of dynamics while also dropping off some of the quietest details

#

strange timbre that's mostly in the techs instead of fr

thin void
#

so! funny enough the techs really are the FR. With a MIRE and your DF-HRTF you can match pretty much any headphone and its all there

#

some other reviewers recently got MIRE setups (with their DF-HRTFs) and are starting to experience this

#

the great news of this is that you really can get there with EQ

elder thistle
#

I don't think that's supported by research in any concrete form, and it's not what I or some other people have experienced

thin void
#

its thrilling

elder thistle
#

IMO claims of FR being everything has caused a lot of damage in terms of what people purchase or think they can get away with

thin void
#

when misunderstood I strongly agree

elder thistle
#

but we don't understand it ourselves

thin void
#

There's growing examples of how far measurement fixtures tend to stray from in-situ

thin void
#

But the ability to match one headphone to another with in-situ measurements shouldn't be surprising

#

now, weather or not those headphones land on a "good" target range is a whole different question

#

and seperate evaluation

elder thistle
#

isn't there research studying peripheral sensory phenomenon and how that can cause different perceived sound regardless of fr?

thin void
#

well there's plenty to show that its affected by mood, comfort, external factors

#

but nothing suggested "acoustically" for things close to minimum phase like headphones besides FR

elder thistle
#

yes but I mean there's more to what gets into our senses than sound pressure at the eardrum

#

and it's not like we have neuralink technology to study what we actually hear versus what's at the eardrum

thin void
elder thistle
#

it seems like it will be too soon to claim FR causes certain things for a very, very long time, even if we solve in-situ fr

thin void
#

I personally say it with confidence but I think that skepticism is extremely fair given this is research that's in early stages. I very much look forward to when more is publicly available and the discussions it will bring.

elder thistle
#

what studies were able to reduce experienced human hearing's possible causes down to solely sound at the eardrum?

#

I will buy an AES subscription if there's really reductive and complete studies like that

thin void
#

to some extent I suppose you could argue that significant displacement of pressure can have effects on various organs or the sinus, but that would be a considerable reach to try and correlate it with how we experience sound.

elder thistle
#

what if the nature of isolation, vibrations, or hf reflections/angles causes our brains to forcibly add a 1.3khz boost

#

or some other effect

thin void
#

so, that's getting into the nature of average listener preference rather than the acoustics. We don't "hear" the natural curve of our HRTF generally in daily life correct?

#

A good example of what reaches our ear drums vs other sensory organs and their ability to perceive them would be like someone shining a small LED at a person while they're sunbathing

#

Now that said, the brain is a huge player for sure

#

its highly debated for in-ears

#

specifically around the notion that the brain "expects" the person's HRTF

#

which seems like a reasonable assumption, and some data suggest it, but is not yet "proven"

elder thistle
#

I didn't mean it like that, I meant that there are more chaotic interactions the sound and the way the sound was injected has inside the ear

#

like the pressure sensation

thin void
#

Like interaction of the middle ear?

elder thistle
#

but possibly much more

#

ye probably middle and internal

#

I'm no audiologist

#

but the ear is made up of so many parts, and the way it sends stuff to the brain is basically a black box as far as we can see, yes?

#

so I think it's awefully dangerous for serious research to be built on the idea that a microphone and pressure simulator/pinnas is a truthful analogy to human hearing

#

it has value, but good science can only happen with a clearly defined scope and knowing the limits of the tools

#

we don't really know the limits of the tools

thin void

I literally had a hardware failure during this conversation 💀 had to switch to my laptop

#

I noticed you're friends with Golden. If this subject interests you ask him about his recent experience with MIRE.

thin void
# elder thistle uh I worded this badly

I think I get what you mean. I've got the 4128 and 5128 here and compared to in-situ measurements its clear how much work is yet to be done on test fixtures and how they relate to humans.

elder thistle
#

we don't really know how limited our tools are as a functional model of human hearing

#

yes

thin void
#

and I think a spotlight on that will be beneficial to the industry

elder thistle
#

I guess from an FR standpoint there's a lot to be improved with accuracy too

#

the odds that FR at the eardrum controls all or most of what someone hears from a headphone is not 0

#

but I'm hoping that conquering frequency response will lead research to study hearing in new ways to really figure out how it all works

thin void
elder thistle
#

I've done a lot of experiments to the capacity that I'm able to, and there's just no way I can currently comprehend that I could have the consistency in my eq's, measurements, blind tests etc. if frequency response was everything

#

but there's also lots of signs in various music production and gaming spaces that hint at patterns much better described by techs than fr

thin void
#

The hard part there is that you still have three invisible factors to contend with. Acosutic-Z, HRTF, and hPtf

elder thistle
#

the tests basically need to test themselves lol

#

like trying to find two unknown angles of a triangle

elder thistle
#

but for example, I've been able to determine some kind of metric for accuracy with how I eq a headphone

#

and that's based on me trying to solve for hidden test eq curves applied in front of a sweep

lean grove
elder thistle
#

some things with phase and waterfalls

thin void
#

EQ by ear can definitely be a challenge. I wouldnt pay mind to phase/waterfalls because often phase is just measuring the phase of the fixture and the filter

elder thistle
#

then there's practical tests for trying to judge if the techs I'm hearing are real, which includes things like dying in games

thin void
thin void
lean grove
elder thistle
#

phase is a good way to look for how off-target two eq curves are from eachother. or what time/phase issues I could be creating if I produce the same error when eqing headphones to my ears

thin void
#

my performance in games is: I'm in my 30s and getting older every day

lean grove
#

Couldn't be me.

elder thistle
#

this also helped me adjust the shape of the eq's I now create

there are a few kinds

I lack the energy/brain cells for the phase rabbit hole today, but it is something I would love to discuss and dive into one fo these days.

thin void
thin void
#

how many years before I cant hear 10khz anymore

elder thistle
#

the point of it was to improve and verify how accurately I can eq by-ear

#

what I've determined so far is that it's very odd that I'm not experiencing the changes in techs that I see mentioned once in a while (in relation to stage width, bass tightness, instrument separation, timbre) compared to the eq's used in their examples to apparently achieve these changes

thin void
#

The hard part is these things really seem to lie in the fine-grain FR and its REALLY hard to land on some of those features by ear alone. Even with the MIRE setup its not easy.

elder thistle
#

I don't think it's likely for me to hear changes in these effects no matter where I'm told to focus the eq

thin void
#

the hard part here being its not exactly about where to focus the EQ and more about that combined with how things response in your ear with your HRTF

elder thistle
#

I've placed so many eq nodes at this point that I would have fixed a section of fine-grained treble fr by random chance

#

or perhaps more interestingly, I would've been able to destroy great hrtf compliance with intentionally incorrect eq changes

#

but the changes don't show up. not on the 70 or so headphones and IEMs I've been able to test that on

#

there are only 2 exceptions: timbre, which seems part-fr and part-tech (as crinacle once wisely said), and extreme cases of masking

#

I know that my testing for how accurately I can eq isn't some professional scientific study, and the accuracy of my eq's therefore remains unproven

#

but not hearing a single change in techs, of any magnitude outside of those two rules, of all the headphones and iems, and all the calibration work involved?

#

it'd be wishful thinking for me to think fr could cause that change

# elder thistle what I've determined so far is that it's very odd that I'm not experiencing the ...

I've mentioned it before, but there are aspects that eq and frequency response won't affectively tell you. This isn't just an idea, but a mathematical fact, especially with the amplitude related transfer and the more commonly discussed intermodulation distortion.

How much these matter is up to further research to determine, but our brains do interpret very small changes to determine the things people would usually describe as "technicalities". I think it's fair to assume these usually small nonlinearities could possibly fall within that incredibly small delta our brains use for perceiving the world already.

There is also the fact that most people just use magnitude response, but in reality, headphones are devices that have a non zero all pass phase, so magnitude response alone isn't capable of deriving our full frequency response. This leaves issues even if we assume frequency response to be all encompassing and assume all other axis are imperceptible.

I'm linking an interesting paper that ties to that last detail.

#

Tldr, don't fully discredit what you're hearing, as it's still well within the explicable realm.

elder thistle
#

the inexplicable realm also deserves full credit

#

the argument could be made that what we don't know or understand is a larger part of the equation for how people hear than the existing established research and the variables it's not considering

#

and I would agree with that argument

#

hearing is incredibly complex, and settling for a microphone as it's analogy is awefully daring

#

but there also seems to be very little research into things like techs and if they're distinct from frequency response

#

it all reads like an adjacent self-validating experiment

#

like watching cavemen fill a car's gas tank with water, then never trying to turn the car on, assuming they were successful in nourishing the car

#

and doing it again and again

lone flame
#

i know people that had their HRTF measured

#

and used special equipment to measure headphones on their ear

#

and they were able to make a HD600 sound EXACTLY like an HD800s

#

with the stage, seperation etc

elder thistle
#

observation is a hard-earned skill

#

as for the accuracy thing, read above.

lone flame
#

"tech"

#

i know 3 people that measured their HRTF and where able to EQ Match headphones to sound identical

#

so what tech u talking about

elder thistle
#

across discord servers I have seen very little evidence that people experience changes in techs as-described when using eq. Techs as an unchangeable phenomenon appears to be so common that it functions as a repeatable way to diagnose needs and preferences

lone flame
#

EQing is just fcking hard to do

elder thistle
#

that is irrelevant

lone flame
#

and if you don't have you HRTF measured, you will never hit it

#

im also able to increase stage etc with EQ

elder thistle
#

That is also irrelevant

#

as I had explained

#

Nevertheless there are no invalid experiences

#

brb

lone flame
#

we need more people to get their HRTF measured

#

and different headphones with in ear mics too

#

to EQ Match them and make a study about it

sleek lily
#

Imagine it like this. If a an imaginary person named Bob says that they know cables mad of gold change sound by doubling the soundstage, and one day they buy a gold cable and plugged it in and say "wow, soundstage doubled", I'd be sceptical. Maybe it did by some unexplained phenomenon, but more likely, they actually heard what they wanted to hear. They probably aren't lying, but the mind is complex. I'd wait in this case for further testing, and I'd personally wait for it to be a fully explained phenomenon.

#

I'd at the very least wait until more people can confirm the same phenomenon to a point where I can say there might be a phenomenon that shouldn't be confirmation bias.

lone flame
#

maybe but i don't think

sleek lily
#

Maybe they aren't

#

But concluding either way is as meaningless of a speculation as it would be before they had their experience. More data unfortunately is necessary.

#

Another thing I want to be clear on, because I see this misrepresented a lot: even the rigorous HRTF + frequency response explanation is not just “EQ skill issue.”

Matching what actually reaches the eardrum is not only about shaping magnitude. In practice the headphone plus ear system is not strictly minimum phase, so you can’t fully derive or recreate everything from magnitude response alone. There can be excess phase and time domain behavior like group delay differences or ringing that don’t map cleanly to a simple EQ curve.

On top of that, the effective transfer function at the ear depends on fit, seal, angle, and how the driver interacts with your pinna and ear canal. Those can change the response in ways that a static EQ made on a coupler or even another person’s ear won’t fully capture.

Then there are nonlinear and level dependent effects. Things like intermodulation distortion, compression, and general level dependent behavior create components that linear EQ cannot reproduce at all.

So even within a framework that emphasizes HRTF and the binaural transfer function, reproducing one headphone with another is not guaranteed to reduce to a single EQ curve. HRTF and FR are clearly important, but when people still hear differences after careful matching, that is not automatically explained away as user error. It can just mean we are not capturing the full system with magnitude response alone.

#

Tldr: even in that framework, magnitude response won't be enough, so it won't be as simple as measuring your hrtf and adding it as a curve to your eq.

elder thistle
#

at any rate, as I mentioned previously the notion that an eq needs to be perfectly matched to change techs is nonsense

#

I am not aware of a single variable on this earth where the behavior only changes when it reaches an exact state

#

it wouldn't be a variable

sleek lily
#

I'd at the very least say it's far from conclusive, with a lot of just as under explored aspects that are just as likely to change those same aspects.

elder thistle
#

what would the headphone change to? how could headphones ever be different? why are there differences in techs that are not 0% and 100%?

#

it's not logical

sleek lily
#

If not more likely, because they tie more directly to known mechanisms that influence these human level interpretations.

#

I'm not going to take a hard stance on this, but I'd say it's disingenuous at best to say all of it must be an "eq skill issue".

elder thistle
#

techs being separate from fr is just my and most people's experiences

#

the actual point is that we don't know as much as we think we know with audio research, and it needs to be addressed

#

I should not be using my experiences and research to give factual explanations on how human hearing works

#

and neither should audio engineers with their experiences and research

#

we haven't reached these facts

white gate
#

I've done the "EQ a headphone to sound like another" thing this week

#

But also, headphones are minimum phase systems, so we've kinda known this would be the case forever.

It's just that actually being able to measure or characterize the in-situ response of two headphones on your head precisely is really hard

#

So it's always been a "In theory you can, in practice not really" thing

elder thistle
#

agree to disagree, but that's interesting you heard it that way

white gate
#

pretty sure @thin void has done this too

thin void
#

I have indeed

white gate
#

But yeah, since headphones are minimum phase, adjusting FR (and therefore phase) to both match, it sounds exactly the same

You just unfortunately need a good MIRE setup to do it precisely

elder thistle
#

it doesn't work for me and a lot of other people

white gate
#

I wish it were more accessible, but the number of people that have actually done this can probably be counted on two hands

thin void
#

Accessibility is really the hard part yeah

white gate
#

hurry the hell up Apple

scan my noggin and run the numbers damn it

elder thistle
#

perfect accuracy is only relevant if you're trying to make two things sound identical, or rather if that's what you're testing

elder thistle
#

perfect accuracy couldn't be mandatory for simply changing techs

in some arbitrary direction and amount

thin void
white gate

It's blunt, but in the words of Oratory1990 to Resolve:
"Skill issue"

elder thistle
white gate
#

I think that's likely to just mess things up

#

peaks =/= detail

elder thistle
#

exactly

thin void
#

I dont think any of us are saying peaks = detail

elder thistle
#

however, adding peaks and dips doesn't change the way I perceive the techs

white gate
#

Hell when I was doing development on the Aperio GSE I found that nearly 100% of the test participants reported "better detail" unprompted by just pulling down lower mids/midbass

thin void
#

^

#

If we can use a MIRE to EQ one headphone to sound exactly like another, techs and all, then would it not makes sense that those techs are a part of the FR?

white gate
#

^^

elder thistle
#

we may be partially on the same page then

thin void
#

the claim isnt "peaks = detail" but that FR certainly is over-all

#

detail is perception of FR

elder thistle
#

so obviously the thing I can speak the most about is my own observations and testing and such

thin void
#

of course

white gate
#

We don't necessarily understand exactly how to EQ something to just straight up sound more detailed.
We don't know an answer in the sense of "oh yeah make 5-7khz slope like this then have a 2dB 8khz bump and boom there's your detail"

But the very fact you CAN EQ one headphone to sound IDENTICAL to another, techs, staging etc and all, shows you absolutely can do it.

(And again, minimum phase systems, it'd be difficult to explain why we WOULDN'T get this result barring some intrusive level of distortion)

We don't know how anaesthesia works but hey you try saying "I refuse to fall asleep, we don't know this works"

elder thistle
#

in the case of ducking the lower mids and hearing more detail from it, this could be interpreted as either hearing more treble / less masking, or it could be an actual change in resolution

white gate
#

people DO hear brighter headphones as "more detailed"

elder thistle
#

if we assume (though I assume the opposite) that lowering the low mids actually creates a change in resolution, then techs are being changed by fr and it's a relatively simple thing I could do on my end to make the techs change there too

#

when I do this, I only hear the results of conventional masking

thin void
#

you can certainly change how you're perceiving the sound

#

but you're not changing resolution because resolution straight up doesnt exist

#

your range is "20khz". If a driver can produce 20khz, then it can move fast enough to produce 20khz

white gate
#

"Resolution", "Soundstage", "Timbre" etc are all just subjective terms used to describe our perception of the FR

thin void
#

^^^

elder thistle
#

hold on

thin void
#

its a language for making sense of it

I get that that's your experiences, but it definitely isn't mine. trying to explain

There are edge cases where distortion might becoming a dominant factor, but very rarely and in those cases you've got bigger concerns tbh

hence why accessability is the barrier

elder thistle

I don't see how that makes the effect more real

so when I listen to a new headphone, I hear a whole lot of things on the first song. the tone is the immediately obvious thing. a few seconds later, I start hearing things that I've recognized in the past as belonging to techs. the more music I play, the more I pin down these techs as well as the frequency response

#

from there, changes to the tone, even fine-grained, even with horrible phase disturbances, are not able to change the distinction between tech and tonality

thin void
#

You are describing a very different experiment with very different equipment

#

It is not surprising you would land on different results

elder thistle
#

not really an experiment, just how I hear and assess a headphone

thin void
#

fair, but im sure you can see how that would have no bearing on the results of this research?

elder thistle
#

when you personally make eq adjustments to a headphone, do you experiences changes in techs?

thin void
#

Absolutely, but the way im making those EQ changes is with measurements from a MIRE system from one headphone to another.

#

when im doing it randomly or by ear? nope

#

but doing it randomly or by ear is like trying to snipe a 700 yard target blindfolded and spun in circles

elder thistle
#

so if you eq down 300hz, you don't experience better resolution like the other people did?

#

you see where I'm trying to go with this

the hd280 pro however has this same boost but sounds super muddy

for that one it helps a lot when 200hz is reduced

thin void
#

the fun part here is we dont know how those measure on your head

elder thistle
#

I presume it's masking the ugliness of whatever unknown nature

#

and that the 440a doesn't have this ugliness, so boosting the region is of little consequence

elder thistle
#

technically we don't, but that's not a good explanation

#

that range is rather consistent across people. I have the ability to perform level matching, and the microphone required to see things happening in the bass doesn't need to be so advanced

another facet of this that is equally important is that terms like "detail" are perceptual and non-standard. 5 people could say "detail" and be describing different percieved aspects of the FR without knowing it

resolution: the ability for overlapping details to not destructively interfere with eachother in an increasing amount with increased instruments. it could be described as smearyness

detail: a perceivable and distinct component in a sound or music

Therein lays a huge part of the problem. Everyone has different definitions of those words (and not everyone would differentiate those particular two in the first place).

And then even if two people DO have the same text definition they don't often have the same actual true meaning or application to particular audible effects/presentations

at some point long after that, I gave them another listen and heard some details being resolved clearly in a particular song

this was a clear sign I screwed up

the issue was that the music I was listening to previously had percussion and effects spanning many regions of the treble simultaneously

this meant I changed my findings of the resolution of the wa'ners

When you're measuring with the rig do you have an ongoing verification to make sure things are still calibrated

there was no longer enough information in each instrument to preserve their identities when they overlapped

elder thistle

it is a rare example of a situation where frequency response feigned the behavior of resolution through masking

elder thistle
#

or at least my ability to hear them as separate things

#

no no, I mean I'm aware of how that explanation could be spiraled up to high frequencies being obscured by adjacent dips and peaks, creating the same effect for finer details

#

frequency response was always a logical explanation for resolution on a surface level

#

and it's heavily used that way in music production

#

but in reality it doesn't work that way for me and lots of other people

the consequences frequency response can create are basically traceable and learnable/removed with brain burn-in

there are other effects on top of this

I accept that a few of you have been able to make headphones change their techs via eq

MIRE and HATS measurements are effectively "separate".

You can't directly compare a 5128 measurement to a MIRE measurement for the same reasons you can't directly compare 5128 to GRAS. Different heads so even after HRTF compensation headphones will behave differently.

What you can do, and what is beneficial, is showing how the same headphone, compensated to the HRTF of each head/rig, then behaves. As the variation is something that is woefully under-represented in current media/publications

#

A headphone might look 'perfect' on 5128 then be screwed on most real heads

elder thistle
#

on that train of thought, I'm hoping to see you guys abstain from broadly saying fr=everything is a factual reality for all people

these studies are useful, and your experiences are too. but if only a few people have experienced one headphone turning into another with EQ, it is not yet scientific law

See that's the kind of stuff I want.

In my business, when the thing that we're analyzing is actively interfering with the measurement we call it matrix interference. Think of some oil coating a sensor, or something interfering with the chemistry.

We have techniques to know how the signal is being affected by something unusual and could compensate for that signal depression.

So in theory, someone could make a dogshit headphone that is engineered to perfectly couple with a dummy rig head and look good, but falls apart when it's put on someone with a more atypical head shape.

Testing that variance could be fun if it didn't involve finding people with different shaped heads and spending hours getting a single measurement.

The DCA stuff is probably the most drastic example atm.
Most headphones behave MOSTLY consistently across heads once you compensate the HRTF contributions away. Closed-backs less so.

But the DCA stuff has those 'meta' filters that do an excellent job of getting a very exact FR in a particular positional range on a particular rig/head, but on real people the results vary a LOT

well the microphone when reading a frequency sweep from a headphone at 1 point (where the eardrum would be) is dominantly reading frequency response

this eq can be done to the recorded data OR the input signal of the headphone. only thd and noise concerns

I did some more research into the minimum phase assumption in headphone applications, and I don’t think it’s correct to say headphones are minimum phase.

From what I can tell, that idea mostly comes from treating them as close enough to minimum phase for EQ purposes, meaning they don’t have extreme excess phase. But that’s just an approximation, and it seems to have been stretched into the stronger claim that they are actually minimum phase systems.

In reality the headphone and headphone ear system has measurable non minimum phase components, so you can’t assume phase is fully determined by magnitude via a Hilbert transform. So saying “headphones are minimum phase, therefore matching FR also matches phase and they will sound identical” is stronger than what that original EQ assumption actually supports.

I gave an analogy for this in another server: if I want to find the distance a ball flies after I throw it and I don't care much for precision, I can make the knowingly false assumption that I have 0 friction. That's actually very normal, but it's not fair for me to make assumptions or derive details off my knowingly false assumption I made for ease of calculation. If I say that because I have 0 resistance I must be in free space, so I have 0 gravity, so the ball goes on forever, I'm wrong, not just off.

But really there is no field of study that would make the serious claim that they are minimum phase. It was derived from a misinterpretation of a knowingly wrong assumption made for ease of calculation, much like my no friction example.

I will also leave this here, because I don't like the suggestion that I didn't read the paper, but I know most people wont actually open it. For those interested, a minimum phase system would show us our minimum phase component through a Hilbert transform, which is why its suggested that we only need magnitude response to interpret a "true" minimum phase system. For a true minimum phase system, we would not see any all pass phase. These are measurements of the phase makeup of different headphones, all of which exhibit all pass phase. The paper accepts this and goes on to say "Lastly, we found all-pass phase in the headphone transfer functions; as this is typically left out in headphone equalization, it has consequences for the temporal performance of equalized headphones" and "In closing, the acoustic influence of the headphone can only be removed if the equalization is based on individual measurement of its transfer function". This all suggests that headphones are not minimum phase (which they aren't considered by any rigorous means), and we need a lot of data to even guarantee behavior for eq. I’ll give the benefit of the doubt and assume the signal-analysis portion of the paper was missed and more focus was given to the conclusion, but that conclusion appears to have been interpreted as meaning the all-pass phase observed at the eardrum is only an HRTF artifact and therefore doesn’t contradict the minimum-phase assumption for headphones, which is not what the actual conclusion, the data or analysis in the paper supports.

TLDR for those who dont want to read all of that, but are interested:the paper shows headphone transfer functions at the eardrum contain all-pass (excess) phase, meaning they’re not strictly minimum phase. Because of that, you can’t assume magnitude alone fully describes the system or that EQ matching guarantees identical behavior.

#

If my wording seemed blunt, it’s because I was responding to dismissals and claims about the paper that didn’t engage with its signal-analysis or data. My goal here is to keep the discussion centered on the evidence and reasoning presented in the paper itself. I hope from this point on the discussion can remain more factually driven and scientific 👍

I’m open to discussing any specific part of the paper or analysis in detail if there’s disagreement on the interpretation.

headphones exist in the physical realm (so do ears) and can't be 100% one kind of sound component

I’m also going to leave this paper here. It’s not directly related to the previous discussion, but it’s interesting, and for those who are more math-inclined it offers a useful way to interpret the data and connect it to one aspect of what people describe as “technicalities.”
For example, the paper notes that “the just noticeable difference (JND) in ITD is nearly constant at 10 μsec as a function of ITD.” For those thinking in signal-processing terms, that gives a concrete way to translate time sensitivity into phase: you can convert that 10 µs into cycles at a given frequency to estimate how much all-pass (excess phase) would need to amount to, per frequency, to be perceptible, assuming no other mechanisms are at play.

sleek lily
# elder thistle I think minimum phase here is just used as a generalization

It seems that “minimum phase” in headphone discussions started as a practical EQ simplification, meaning they behave close enough that you can adjust magnitude without running into large phase problems. That’s a reasonable approximation.
But over time that seems to have turned into the stronger claim that headphones are literally minimum phase and that we can derive full phase from magnitude alone. From what I’ve been reading, headphone plus ear systems do show non minimum phase components, so treating them as strictly minimum phase is an approximation, not a physical property.

white gate

#

Here is another interesting paper I found. I haven’t had a chance to fully read it yet, but it seems to suggest there may be an amplitude-related component to phase. If that holds up, it would support the idea that we may need to look more closely at amplitude-dependent transfer behavior in these systems.

sleek lily
#

It's not that they are minimum phase

#

But it's more accurate to say our non minimum phase system's phase makeup is close enough for a simple eq purpose

#

But treating it as a law, and then using that false law as a way to derive things against physics is bluntly wrong.

@lone flame If you're interested in this topic though, I do suggest reading the papers I linked. I also included summaries for the first two, but I still recommend reading the whole papers

white gate
# sleek lily A lot goes on between those points

"A lot" that contributes basically nothing as shown by the above graph.

We're not talking binary absolutes here. If you want to talk about behaviour down the planck second then cables aren't minimum phase. But that's not how the term is used.

The primary reason and contributing factor to headphones behaving non-minimum phase is nothing to do with acoustics, but simply harmonic distortion. Thankfully that in most headphones is extremely low

sleek lily
# white gate "A lot" that contributes basically nothing as shown by the above graph. We're n...

Harmonic distortion isn’t what determines minimum vs non-minimum phase. Distortion is nonlinear; minimum-phase vs all-pass is about the linear transfer function. You can have negligible distortion and still have measurable excess (all-pass) phase in the headphone + ear system due to acoustics and geometry. So “they’re minimum phase” is at best an EQ approximation, not a strict property.

Please look at the phase-decomposition paper I posted. It shows non-minimum-phase components directly. And try the ITD math I shared: a ~10 µs JND translates to only ~0.01–0.1 cycles depending on frequency, which is far below the cycle-scale excess phase seen in measurements. That doesn’t prove audibility in every case, but it does show there are real axes beyond magnitude that can matter.

If you’re claiming it’s inaudible, please provide controlled evidence or cite studies showing those phase/time differences are below known perceptual thresholds. There may be mechanisms I’m missing, as I mentioned earlier, but simply asserting that measurable, calculable differences don’t matter without evidence isn’t sufficient for a scientific discussion.

white gate
#

Even if you just ask Gemini or something

sleek lily
# white gate Please read into this further, especially that first part

Saying “ask Gemini” or just asserting it’s negligible isn’t an argument. If you disagree, please explain where the reasoning is wrong or provide evidence or a model showing those phase/time differences are below perceptual thresholds.

Right now I’ve cited measurements, a phase decomposition analysis, and psychophysical ITD sensitivity. If those are incorrect or not applicable here, I’m open to that, but it needs to be addressed directly rather than dismissed.

#

If you’re speaking from personal experience or preference, that’s totally fine. Just let’s not present that as a scientific conclusion. 👍

white gate
#

You've been unwilling to accept evidence presented in the past, and frequently present evidence you don't fully understand yourself, as well as pushing presumptions or questions as evidence of factual innacuracy
