Hi Alessandro

On a related note. Do you know how to split the left and right channel? I want to be able to control the vol. on each channel separately. I guess I could implement this using a render callback how ever it seems like this is fairly common functionality. I assume there is an easier way

Thanks

Andy

Subject: kAudioUnitSubType_Merger on iOS

Is it aloud to use kAudioUnitSubType_Merger in iOS? 

in the headers there is : 

@constant kAudioUnitSubType_Splitter

- desktop only

An audio unit that provides 2 output buses and 1 input bus. The audio unit 

splits (duplicates) the input signal to the two output buses

@constant kAudioUnitSubType_Merger

- desktop only

An audio unit that provides 2 input buses and 2 output bus. The audio unit 

merges the two inputs to the single output


but going down there is : 

enum {

kAudioUnitSubType_AUConverter = 'conv',

kAudioUnitSubType_Varispeed = 'vari',

kAudioUnitSubType_DeferredRenderer = 'defr',

kAudioUnitSubType_Splitter = 'splt',

kAudioUnitSubType_Merger = 'merg',

kAudioUnitSubType_NewTimePitch = 'nutp',

#if !TARGET_OS_IPHONE

kAudioUnitSubType_TimePitch = 'tmpt',

kAudioUnitSubType_RoundTripAAC = 'raac'

#else

kAudioUnitSubType_AUiPodTime = 'iptm',

kAudioUnitSubType_AUiPodTimeOther = 'ipto'

#endif


and I also found this on stackOverflow: http://stackoverflow.com/questions/9383866/is-there-a-replacement-for-ausplitter-in-ios/14843261#14843261


talking about the ability to use the splitter in iOS environment.
