I am implementing the PortAudio cross-platform API on top of CoreAudio. This
will allow us to port lots of apps very quickly to OS X. I need to support
multiple sample rates but CoreAudio only supports the HW sample rate. So I
would like to use the AudioUnit that does sample rate conversion. I want to
use an SRC AudioUnit to rate convert audio input before passing it to
PortAudio, and then do the opposite conversion for the audio output. But I
only see output AudioInputs.
Question: Is there a HALInput or DefaultInput AudioUnit that I can use with
the SRC unit to convert audio input?
Thanks,
Phil Burk
