i just got a loudness meter by youlean and i’m beyond lost w all the numbers and lines and what not
any expert could gimme a rundown on what’s important and what i should be focusing on to make my mix loud and clear

fiery topaz
#

possible reference

pure kiln
#

ooh

#

thanks

#

i just used it for a beat i made and it wasn’t really quiet like all my other beats

fiery topaz
#

Honestly I never use it, I don't know if I should but I find it easier to make sure everything is loud and not clipping.

pure kiln
#

interesting

fiery topaz
#

ends up like this in the meter

pure kiln
#

how do you

#

get the lufs high

#

but the true peak is 0.1

#

my lufs were like -14

#

help

#

wait aren’t the red dots on the top all bad

#

or no

fiery topaz
#

I am not sure how its still peaking as a wav, but i think the red just means its peaking there and is clipping

#

it still sounds good to me and its not as bad as other squashed mixes I have heard

#

for example (super squashed mix):

pure kiln
#

oops

#

how the hell

pure kiln
#

@fiery topaz

fiery topaz
#

its all about gain staging

#

make things loud yet staged well

#

what db are you hitting?

pure kiln
#

on true peak?

fiery topaz
#

what daw do you use?

pure kiln
#

garageband

fiery topaz
#

Does garageband have a limiter on the master channel?

pure kiln
#

yes

fiery topaz
#

is your signal reaching the ceiling?

pure kiln
#

i’m pretty sure

#

idk tho i’m not looking at it rn

fiery topaz
#

Well in general I would make sure to keep the signal as loud as possible with clipping and with every instrument sounding how you want

pure kiln
#

right right

#

i’ll try gain staging

#

didn’t do that in this one

fiery topaz
#

its okay to clip a little

#

maybe a few db

#

but you dont want your audio completely nuked everytime a kick lands

pure kiln
#

well naturally

#

but

#

so

#

my kick might be too quiet then

#

interesting

#

damn my snare is quieter than a breath

#

don’t know how i didn’t hear it

fiery topaz
pure kiln
#

oh reference

fiery topaz
#

also ask yourself the question, "Is this element important?"

pure kiln
#

well a snare seems rather important

fiery topaz
#

yeah, so being able to hear it would be nice for the listener

pure kiln
#

you’re right

#

how could i have missed

fiery topaz
fiery topaz
#

thought it was interesting as I have never seen anything in that range of LUFS

#

The producer is definitely winning the loudness wars i guess.

limpid hinge
#

Sigh...

#

Well

#

It's cheating

fiery topaz
#

care to explain?

limpid hinge
#

They're most likely metering in the project session, i.e. with float processing, so they can arbitrarily increase gain to get arbitrarily high LUFS numbers

fiery topaz
#

metering a rendered lossless file is that much different from the session?

limpid hinge
#

Yes, because you're normally rendering in integer precision

fiery topaz
#

I see, that changes a lot for me.

#

I usually just mix and "master" all from the session and then export and be done

#

but I think I have to mix, leave a little headroom, render, then begin mastering

limpid hinge
#

Not really though

#

You don't need headroom for mastering, you just shouldn't be clipping at any point where you're going into integer precision

#

There's also nothing technically wrong with mastering in the same session, it's more of a workflow decision

fiery topaz
#

Well if you meter in the session I would still need to render

#

so yeah workflow decision

limpid hinge
#

Not really, no, because you're metering to see the issues and fix them

fiery topaz
#

So fixing the issues in the session will eliminate the issues in the render?

#

wouldnt there be added peaks in the render though?

limpid hinge
#

This is all about clipping. Audio generally can't clip in the DAW, but it can clip on export/render and it may clip on playback (also may not - depending on your audio setup and routing). That means metering in the DAW can't tell you that you're clipping, because you aren't - metering can tell you that you will be clipping on export, and that's what it does. Conversely, because you can't clip, you can just raise your gain through the roof and because it's not actually clipping yet, the LUFS value will rise through the roof as well - only it won't mean anything, because LUFS is defined with respect to integer full scale (hence the "FS") and that just doesn't exist in float audio. So if you're peaking above 0 dB, the LUFS value becomes meaningless. It's like saying "15" when you're asked to rate something on a scale of 1 to 10

#

There are a lot of other reasons to want to avoid clipping, but that's a different story altogether

fiery topaz
#

I see what you mean. I didnt know you couldnt clip in a daw

#

just tried it out, this is really interesting to learn about

limpid hinge
#

Yeah it's because the daw internally uses float point precision for the calclation, and that simply has no "maximum value" (for all practical purposes)

Damn

SAMN

#

287 is crazy

limpid hinge
#

If you still think that you might not have understood my explanation earlier 😄

pure kiln
#

yes i know it’s irrelevant once you start clipping

#

just saying it’s wild

limpid hinge
#

It's math. Addition, really 😄

pure kiln
#

cool cool

pure kiln
#

@fiery topaz thanks for that ref photo

#

damn it sounds so loud now

#

i got it to -7

#

limiters are basically cheat cldes
