You just need to set those properties on the input scope of the desired channel(element).

float pan = 0;  //  -1  -> 1
AudioUnitSetParameter (MixerUnit, kMultiChannelMixerParam_Pan, kAudioUnitScope_Input, channel, pan, 0);

I created an AUGraph to play music from iTunes library. I added mixer unit and effect unit to the AUGraph in the following order

FilePlayerUnit->MixerUnit->EffectUnit->OutputUnit

Now I am trying to change the volume balance between left and right channel. 

How can I increase, decrease or mute volume in a single channel. Is it possible to do this with FilePlayer Unit that plays music files from local storage?


Regards
Clement
