Select input media device for audio recording using web audio APi

Question

Can we set the device from which the audio should be recorded in mediastreamRecorder API using enumerateDevices using Web Audio APIs?

Answer 1

Sure, you have to first get the specific device's audio stream using navigator.getUserMedia and then pass the stream to mediastreamRecorder

Answer 2

As stated in this answer, Selecting the audio device is the job of the operating system as you can see in the picture below. Thus you would need to construct a plugin that operates at the OS level in order to call into the OS to switch audio devices.

It would be a security risk to just let an app choose what media input device it wanted to use
