Hi Russ

I ran into this issue a few weeks ago and I ended up just writing a simple PCM mixer
instead of trying to use the graph APIs. See example #4 at this URL for the source
code and an example Xcode project. The download includes a iPhone app and a
command line app for Mac OS X.

I am trying to mix two wav tracks together on the iPhone, on Mac OS X,
I was able to use the fileplayer Generator AUnits.
On the iPhone, what is the way to do this? I was looking into render
callbacks, if I were to use those, what is the input procedure
I would use to play the tracks? Thanks for any help, my setup for
callback units I think would be...

Callback   0 ------  \
                                3DAUMixeriPhone  0   -------- 0
Generic Output  ---->
Callback   1-------  /
