I mean, should be as easy as recording your own zoom call with the Watermark enabled and a well known audio track (a metronome, dead silence, etc). Rip audio from the recording and examine it for anything outside of the metronome.

Probably need to do this several times for different participants and meetings to get an idea of what the watermark looks like and where in the spectrum it sits.

Perhaps they have countermeasures for this? Maybe a unique identifier for each meeting that alters the audio signature.

That's why it'd be necessary to record several meetings and see how things change between them.

Easier way would be to get 2 copies of the same stream from 2 or more clients then compare. Repeat until extra/missing data is found.
