I downloaded the mac app, configured a virtual device to send the system output to the "Krisp Speaker" and verified that it cuts most of the music out of what I'm listening to, leaving only the voice (at a some what degraded quality). I wish I could configure it _cancel_ ambient noise, not just remove it from the input signal.

In your perception, what is the difference between "cancelling" a signal and removing it?

It'll not be quick enough for phase cancellation, but presumably you could diff the output with the input, phase-invert it, and get the signal you want that way.
