こんにちは TAG-さん!

I'm requesting an early TAG design review of Echo Cancellation Mode

This proposal adds the ability for Web applications to better control how much of the user system playout is removed from the microphone signal when a getUserMedia call is made. More specifically, the application can request to remove only audio coming from remote users via peer connections (good for music lessons), or it can request to remove all system audio (better for privacy), or let the UA decide what to remove.
