I'd like to divert - that is, "tee-off" - the audio output in my MiniPC to a file. I'm running Debian 10.1.

For example, if I'm in a video conference and take a break, I'll often switch to a music player until the conference resumes. I need both audio feeds, and the easiest way to capture the conference, the music and anything else is to divert the audio stream at the DAC input before it goes to the audio output socket.

I've not tackled this sort of low-level audio data manipulation before and am wondering if there are Perl modules that could be used to write a quick utility to switch the capture facility on and off.

With thanks for any assistance.
