Properties
const void *	data
	The audio data containing raw audio samples.
int	bitsPerSample
	The number of bits per audio sample.
int	sampleRate
	The sample rate of the audio data, which is either 48kHz or 44.1kHz.
size_t	channelNumber
	The number of audio channels defining whether the audio is mono, stereo, or has more complex channel configurations.
size_t	frameNumber
	The number of frames in the data array. The number of frames is dependent on the sample rate and chunk time.

Detailed Description

Audio frame that contains audio data. Used with MCCustomAudioSource/onAudioFrame: to feed custom audio frames into source used by a MCPublisher.

var frame: MCAudioFrame = MCAudioFrame()
var source: MCCustomAudioSourceBuilder().build()
frame.bitsPerSample = 32; // We are using Float32 as an example
frame.channelNumber = numChannels
frame.sampleRate = Int32(sampleRate)
frame.frameNumber = Int(sampleRate * chunkTime / 1000);
// Imagine audioData is a pointer to some data
frame.data = UnsafeRawPointer(audioData)
source.onAudioFrame(frame)
