I do what you're describing with VB-CABLE on Windows (and Blackhole-2ch on macOS) + OBS https://vb-audio.com/Cable/index.htm https://vb-audio.com/Cable/index.htm So, if you wanted to transcribe the audio from one of your physical output devices (say you had your meeting software outputting on external headphones), you could set the virtual audio device as the monitoring device on the physical external headphones. Therefore, you end up with a virtual audio input device containing the audio from your meeting software. I also do this to apply a chain of filters to my condenser mic in OBS because it picks up everything.
