    public class AVAudioInputNode
    extends AVAudioIONode
    implements AVAudioMixing
    AVAudioInputNode A node that performs audio input in the engine. When the engine is rendering to/from an audio device, this node connects to the system's audio input. When the engine is operating in manual rendering mode, this node can be used to supply the input data to the engine. This node has one element. The format of the input scope reflects: - the audio hardware sample rate and channel count, when connected to the hardware - the format of the PCM audio data that the node will supply to the engine, in the manual rendering mode (see `setManualRenderingInputPCMFormat:inputBlock:`) When rendering from an audio device, the input node does not support format conversion. Hence the format of the output scope must be same as that of the input, as well as the formats for all the nodes connected in the input node chain. In the manual rendering mode, the format of the output scope is initially the same as that of the input, but you may set it to a different format, in which case the node will convert.

        Description copied from interface: AVAudioMixing
        Returns the AVAudioMixingDestination object corresponding to specified mixer node and its input bus When a source node is connected to multiple mixers downstream, setting AVAudioMixing properties directly on the source node will apply the change to all the mixers downstream. If you want to set/get properties on a specific mixer, use this method to get the corresponding AVAudioMixingDestination and set/get properties on it. Note: - Properties set on individual AVAudioMixingDestination instances will not reflect at the source node level. - AVAudioMixingDestination reference returned by this method could become invalid when there is any disconnection between the source and the mixer node. Hence this reference should not be retained and should be fetched every time you want to set/get properties on a specific mixer. If the source node is not connected to the specified mixer/input bus, this method returns nil. Calling this on an AVAudioMixingDestination instance returns self if the specified mixer/input bus matches its connection point, otherwise, it returns nil.

        format - The format of the PCM audio data the block will supply to the engine
        block - The block the engine will call on the input node to get the audio to send to the output, when operating in the manual rendering mode. See `AVAudioIONodeInputBlock` for more details

        YES for success
