Echo cancellation on recording/mixing

mixAudioStream(stream) {

  if (stream.getAudioTracks().length > 0 && this.audioDestination) {




The reason I want to do this is that I have a need to record 2 inputs from the same computer for 2 people talking to each other face to face, with a camera & mic facing each person.

The problem, I think, with echo isn’t feedback from any speaker, because the echo is there when wearing headphones.  I think the echo is from different latency lengths from different mics.

I know there are other ways of dealing with this.  The simplest way is to have 1 shared mic between the two people.  That’s probably what I’ll use.  The other slightly more complex way is to use 2 analog mics combined into the same input.   Another way would be to apply echo cancellation after the video is recorded or processed.
