is It possible to set Room size for audio playback in iOS? (For example kReverbRoomType_MediumHall, kReverbRoomType_LargeChamber, kReverbRoomType_LargeHall2 )

I tried kAudioUnitSubType_SpatialMixer and setting kAudioUnitProperty_ReverbRoomType property. But it is not working.

AudioUnitSetProperty(myPlayer.mxUnit, kAudioUnitProperty_ReverbRoomType,
kAudioUnitScope_Global, 0, &theValue, sizeof(theValue)

//I tried setting all the three scopes

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
