Save audio from any website, as well as any application running on your Mac. You can even record all the system audio at once!
If you can hear it on your Mac, Audio Hijack can record it, and more.
A tool recommended on mastodon for routing, joining, and splitting audio on mac.
Looks to have a nice UI, and runs as a regular user which is pretty neat.
They also have Piezo, a simpler and cheaper tool.
