}

About

Used by InputChannel and AudioDevice.createInputChannel(). The first four options are passed to getUserMedia() as constraints, so they are applied the next time a device is opened. They have no effect on streams passed to setMediaStream().

The browser's voice processing is disabled by default, so effects receive the unprocessed signal. That is what you want for music, instruments and sound design. For voice chat, enable echoCancellation, noiseSuppression and autoGainControl.

Properties

• echoCancellation: boolean - Browser echo cancellation. Default false.
• noiseSuppression: boolean - Browser noise suppression. Default false.
• autoGainControl: boolean - Browser automatic gain control. Default false.
• channelCount: number | null - Preferred amount of input channels (1 = mono, 2 = stereo), passed as an ideal constraint. null lets the browser decide. Default null.
• fallbackToDefault: boolean - Whether the default input device is opened when the current input device is disconnected. Never applies to external streams. Default true.
