Audio clicks / cracklings with ffmpeg audio recording on mac os

Question

I'm having audio clicks on my ffmpeg audio recordings. If I record with OBS for example, the audio comes out just fine. This is what I put in the terminal:

ffmpeg -f avfoundation -i ":0" test.mp3

where 0 is my Soundflower audio device, which I found using ffmpeg -f avfoundation -list_devices true -i "", which returns:

AVFoundation audio devices:
[0] Soundflower (2ch)

Soundflower, my speakers, and the ffmpeg recording are all set at 48kHz. There is another thread that states that this may be an issue with ffmpeg version 4.3, and to try to downgrade to 4.2; I tried to google how to downgrade on brew, but didn't find anything.

Answer 1

Had same issue and downgrading to 4.2 did in fact fix the crackling.

You can grab a prebuilt 4.2 Mac binary from https://evermeet.cx/pub/ffmpeg/ffmpeg-4.2.3.zip (it's linked from https://ffmpeg.org/download.html#build-mac)
