on screenshot command is python3 python/visualization.py but i getting same error with python3 python/visualization.py /tmp

seems that your lib can't find Virtual Audio Input of Loopback (i were getting same error when just installed all python dependencies and tried to run python3 python/visualization.py without Loopback setup). Didn't found any issues like mine, any advice please.

I had a similar issue, something to do with Big Sur.

Run these: brew uninstall portaudio brew install portaudio --HEAD

Should fix it

@osbash yeah, reinstalling portaudio helped
