AVAudioSinkNode
An object that receives audio data.
Declaration
class AVAudioSinkNodeOverview
You use an AVAudioSinkNode to receive audio data through AVAudioSinkNodeReceiverBlock. You only use it in the input chain.
An audio sink node doesn’t support format conversion. When connecting, use the output format of the input for the format for the connection. The format should match the hardware input sample rate.
The voice processing I/O unit is an exception to the above because it supports sample rate conversion. The input scope format (hardware format) and output scope format (client format) of the input node can differ in that case.
An audio sink node doesn’t support manual rendering mode, and doesn’t have an output bus, so you can’t install a tap on it.
