An object that monitors average and peak power levels for an audio channel in a capture connection.
Mac Catalyst 13.0+
You do not create AVCaptureAudioChannel instance directly. Instead, an AVCaptureConnection object that connects an input producing audio to an output receiving audio exposes an array of AVCaptureAudioChannel objects, one for each channel of audio available. You can poll for audio levels by iterating through these audio channel objects.
