abstract Unit	`registerAudioRecordingCallback(executor: Executor, cb: AudioManager.AudioRecordingCallback)` Register a callback to be notified of audio capture changes via a `AudioManager.AudioRecordingCallback`.
abstract Unit	`unregisterAudioRecordingCallback(cb: AudioManager.AudioRecordingCallback)` Unregister an audio recording callback previously registered with `registerAudioRecordingCallback(java.util.concurrent.Executor,android.media.AudioManager.AudioRecordingCallback)`.

registerAudioRecordingCallback

Added in API level 29

abstract fun registerAudioRecordingCallback(
    executor: Executor, 
    cb: AudioManager.AudioRecordingCallback
): Unit

Register a callback to be notified of audio capture changes via a AudioManager.AudioRecordingCallback. A callback is received when the capture path configuration changes (pre-processing, format, sampling rate...) or capture is silenced/unsilenced by the system.

Parameters
`executor`	Executor: `Executor` to handle the callbacks. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`cb`	AudioManager.AudioRecordingCallback: non-null callback to register

unregisterAudioRecordingCallback

Added in API level 29

abstract fun unregisterAudioRecordingCallback(cb: AudioManager.AudioRecordingCallback): Unit

Unregister an audio recording callback previously registered with registerAudioRecordingCallback(java.util.concurrent.Executor,android.media.AudioManager.AudioRecordingCallback).

Parameters
`cb`	AudioManager.AudioRecordingCallback: non-null callback to unregister
