Title: Re: channel mapping a Varispeed audio unit
The varispeed’s channel capabilities don’t do this.
However, you can have the varispeed processing mono buffers, then set the channel map on the output unit to duplicate the mono channel into the stereo output of the device. If you want to do any mixing, you could also easily add a stereo mixer unit between the varispeed and the output unit (and then pan the mono input to your heart’s content)

Hello.
I have set up an AUGraph whose data path looks like this:
ring buffer --> varispeed --> output unit
How do I map mono input in the varispeed to stereo output?
I have tried kAudioOutputUnitProperty_ChannelMap but I get kAudioUnitErr_InvalidProperty.
I used kAudioConverterChannelMap to accomplish the same thing in an AudioConverter.
I was hoping that I could just use the varispeed to accomplish this.
