Hi everybody, I'm trying to use the multi input of an usb device using the AVAudioEngine.
My aim is to connect different inputNode channels to 2 or more different audionode (f.e. mixer).
I'm able to get a spefic input channel from the engine inputNode with
OSStatus err = AudioUnitSetProperty(avEngine.inputNode.audioUnit, kAudioOutputUnitProperty_ChannelMap, kAudioUnitScope_Output, 1, outputChannelMap, propSize);
but this will change the routing to all the input node and to all the destination mixer nodes.
How to send channel 1 of inputNode to a mixerNode1 and channel 2 to another mixerNode2?
