How do I record the screen and the audio being produced? (Ie, not my mic, but the program output?)
The instructions don't say and regular screen recording doesn't seem to catch the audio.

Not sure if it still works in Big Sur, but search online for Soundflower. It’s a kernel extension (AFAIK) that redirects system audio output to system audio input.
To use it: Choose Soundflower (2ch) as your sound output device. Then, choose Soundflower (2ch) as your microphone.
NOTE: You won’t hear any audio when Soundflower is capturing your system audio. If you want to hear your audio output at the same time, you could create a Multi-Output Device that consists of the internal speakers and Soundflower (2ch). (Applications -> Utilities -> Audio MIDI Setup).
