In the docs and header the maximum value of kMultiChannelMixerParam_Volume is 1.0 (unity gain)
However, i've noticed that passing values above 1 seems to increase the volume a little extra. Values above 2 seem to negate this effect.
AudioUnitSetParameter(self.micmodule.submixerUnit,kMultiChannelMixerParam_Volume,kAudioUnitScope_Input, 0, 2.0 ,0);
I would like to make use of this boost in my soundboard app - is there an actual amplification of the signal happening here? |
