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
