Does anyone know of any utilities that could automate the conversion of a stereo audio file to mono? Preferably, something that watches a folder and just runs on new audio files saved to that folder.
You can do it with Python.
from pydub import AudioSegment sound = AudioSegment.from_wav("stereo.wav") sound = sound.set_channels(1) sound.export("mono.wav", format="wav")
That will convert stereo to mono. You can probably use it as a script in for example Hazel.
Alternative option could be
Ended up going with this FFMPEG option, as you have to install that anyway to get the Python solution to work. Created a little automator workflow with it. Thanks!
