get mac audio output level

[nyxaria]

Hi thanks so much for your work on this!

I was wondering if this package can get the instantaneous audio level of a mac (ie youtube videos, music files) that are being played? Or, failing that, if any audio is currently being played on the mac?

I am currently using this script if [[ "$(pmset -g | grep ' sleep')" == *"coreaudiod"* ]]; then echo audio is playing; else echo no audio playing; fi however I have found it to sometimes trigger even when audio is not being played

many thanks!

Soundcard does not currently support loopback recording on macOS. If you know how to do it, I'd be happy to accept a pull request.
