Block to receive audio data from AVAudioSinkNode
Parameter timestamp: The time at which the input data will be rendered.
Parameter frameCount: The number of sample frames of input provided.
Parameter inputData: The input audio data.
The engine will supply valid buffers in inputData’s mBuffers’ mData and mDataByteSize. mDataByteSize will be consistent with frameCount.
