node type change results in no output with multichannel


  • Subject: node type change results in no output with multichannel
  • From: Michael Hanna <email@hidden>

made an AUGraph as such:  output -- varispeed -- fileplayer

and simply changed
	// varispeed AU node
	AUNode timepitchNode;
	cd.componentType = kAudioUnitType_FormatConverter;
	cd.componentSubType = kAudioUnitSubType_Varispeed;

to:

	// varispeed AU node
	AUNode timepitchNode;
	cd.componentType = kAudioUnitType_FormatConverter;
	cd.componentSubType = kAudioUnitSubType_TimePitch;

(and renamed the corresponding variables)

and it seems that multichannel audio does not give output anymore (mono and stereo work fine).

the entire code section can be found at:
