| Hi,
Has anyone had success getting individual meter levels for the inputs of the AUMultichannel mixer in an AUGraph? I can get the output meter levels with:
OSStatus result = AudioUnitGetParameter(mixerUnit, kMultiChannelMixerParam_PostAveragePower, kAudioUnitScope_Output, 0, &valueL);
using kMultiChannelMixerParam_PostAveragePower + 1 to get the R channel values.
I am trying to get the input levels, however a similar approach and setting the scope to Input just seems to echo the output levels. I can’t find any reference to specifying the different input channels in AudioUnitParameters.h. If I have an 8 X 2 mixer, I need to be able to show 8 input meters and the stereo output levels.
Any suggestions would be greatly appreciated.
