Previewing Microphone before joining the room

[patryk-sredzinski]

Is there any way that I can run the microphone track and preview it before joining to any room?
I am able to do it with camera by creating local track and starting it, but for audio track it looks like I need it to publish it first to the room which is something I don't really want.

Would be nice that when I start the microphone/audio local track it actually launches the microphone and I am able to read it's buffers.

let localAudioTrack = LocalAudioTrack.createTrack()
try await localAudioTrack.start()
AudioManager.shared.add(localAudioRenderer: self)

The code above does not render any buffers until I publish it to a room.
I can also confirm that my microphone is not enabled as I cannot see the orange dot on my iPhone

Hey, I would like to search for it a bit deeper in the SDK, but I'd love to get at least some highlights where to start searching for this

Hi, I'm already working on this.

Awesome, Is there any PR or anything that you could link into this Issue so I could observe those changes. Do you have any ETA for this? Thanks @hiroshihorie

This is the PR: webrtc-sdk/webrtc#158
I'm still working on this.

This is now possible by calling AudioManager.shared.startLocalRecording()
