You need to use GrAudioSource.  There will be 2 outputs, one for the left
channel, one for the right, both in char, short, or int format.  You'll need
to convert to a complex number if that is what you want.  I think I have
some example code at home, and will try to send it out tonight.

You should also use GrAudioSink for the corresponding output.  It will
actually take a VrComplex input.
