A short background. I organized a video conference with remote employees and colleagues who were in the same room with me. The entry point to the conference for employees from the room was my laptop: it received audio and sent it, along with video, to a large electronic board that has speakers. To avoid acoustic feedback, I used AndroidMic and connected my phone to my laptop as a microphone.

The problem was half solved: while the stuff in the room were getting good sound, the remote employees were still experiencing acoustic feedback. The most effective solution was to periodically turn off the microphone on the client's side for video conferencing (laptop).

Therefore, there was a suggestion to add a microphone mute button on the android client. It would be cool to do this by pressing or holding a button.
