This is very specific to Unity.
A few testers are reporting that their microphone output isn't being detected. The code below works for the vast majority of users, but certain microphones seem to be outputting on the wrong channel (R maybe)?
AudioClip current_microphone_recording_clip = Microphone.Start(microphone_name, true, 30, 16000);
How can I capture and analyze output from several channels? I don't see any channels parameter for Microphone.Start
