I'm not familiar with the 'parec' command. Are you able to filter out other audio streams (e.g. Slack alerts or accidentally opening a page with an auto-play video)? I was under the impression that one of the big advantages of Pulse Audio was its ability to separate multiple streams. Interestingly enough, I had similar scripts about 15 years ago pre-Napster. The earliest mp3 sharing sites tended to push full-albums instead of breaking things up by track. I had a lot of fun using some of the earlier mp3 tools to break up and tag tracks. I still have a lot those mp3s on various HDs, and I know it because my splits weren't perfect for certain tracks that don't have 2 second gaps.
