what kind of compression do you want?
you can do any of the compression that you currently would do with
audio queue with Extended Audio File - (which uses the audio
converter, which you can use as well)

Hello
(iPhone platform)
I need to do some audio analysis on the incoming audio stream, and
then save it to a file. I am doing this now successfully using
AudioQueues.
I would like to be able to compress the audio so that the saved
files will not be so large. To my understanding, if I set up a
compressed format, then the incoming audio in the handler is already
compressed, so I can't analyze it. I have tried this.
Is anyone aware of either 1) a way to use the SDK to do the
compression, or 2) an existing library or some code that I could
link in, to compress the PCM manually.
many thanks
Andrew Smith
