• Explain what you expect to happen and what actually happens.

heres the other half

it exports the file and all but it doesnt save any audio from my desktop

[swift bridge]

Ok, next time use the pastebin:

!paste

[compact yew]

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

[sleek pawn]

oh alr

https://paste.pythondiscord.com/7PCA

[swift bridge]

So it's creating a file but with no sound?

[sleek pawn]

yeah

now it doesnt even save

the keybinds dont work

[swift bridge]

What did you change then?

[sleek pawn]

nothing, all of this was chat gpt'ed

but it worked

it saved the file in a folder

but no audio

now it doesnt work when i press the hotkey again

[swift bridge]

Are you running multiple copies at same time?

[sleek pawn]

nope

[swift bridge]

The audio interface may already be locked by another process. Does it just hang?

[sleek pawn]

and then once i press it again

it does nothing

[swift bridge]

Yah, so kill any Python process and try again. Check task manager.

[sleek pawn]

none are open in task manager

i think this whole thing just needs to be remade fully

since chatgpt is hella bad

[swift bridge]

Next time, start with the minimum and don't add features like keybinds until the core feature (recording works. Makes debugging easier

[sleek pawn]

true

[swift bridge]

But, in this case, the lack of audio may be because patio is selecting the wrong device. See https://stackoverflow.com/questions/40704026/voice-recording-using-pyaudio#40704898 for a discussion. Basically, list out your devices and figure out which one is your microphone. Then pass that device index to pyaudio

for why the key bind stopped working: add some print statements so you can isolate where it's 'stuck'

[sleek pawn]

idk anything about python sorry

[swift bridge]

Now's a good time to learn!

[sleek pawn]

i gtg gonna get on this later

def select_input_device(p):
    for i in range(p.get_device_count()):
        print(i, p.get_device_info_by_index(i)["name"])
    device_index = int(input("Enter the index of the input device: "))
    return device_index```
but found a way to select the device

just need to make it save forever onto that

and then record the audio using that

[earnest night]

def select_input_device(self, p):
    for i in range(p.get_device_count()):
        print(i, p.get_device_info_by_index(i)["name"])
    self.device_index = int(input("Enter the index of the input device: "))

add this as a method instead of a function

and use the device_index attribute to specify
