Is the iPod app playing at full volume? I'm guessing not. Is your app's audio queue playing at volume=1.0, the default? I'm guessing yes. You should be able to eliminate the clipping by reducing it.

I'm playing foreground sounds by RemoteIO over a background sound by
AudioQueue.  On occasion I hear what appears to be clipping -- very
short sections of light static.   Inspecting the waveform, the peaks
at those points are flattened.

If I play the same foreground sounds over a background by the iPod
player, I don't ever hear this clipping. Even if the volume of the
background from the iPod player is greater than the volume of the
background from the AudioQueue, I still don't ever hear this clipping.


Is the iPod player doing something the AudioQueue isn't?

Thanks for any info.
