Use the ExtendedAudioFile

Open the ExtAudioFile and set the client format to be the same as the format you are going to get from the offline audio unit.

Then, as you get the results of AudioUnitRender from the offline AU, just take that buffer and call ExtAudioFileWrite and you're done

I'm working on a utility that utilizes one audio unit to analyze the
source, and a second to perform changes to a given file based on the
analysis of the first audio unit.

For the analysis unit, I have it hooked up to a DefaultOutput unit, since
I don't care where that output goes; its just pass through anyway...


The processing that takes place after this will happen offline. I want to
take the result of the process and write it to a new audio file. Is there
an Output unit that writes files? or what sort of arrangement would work
to accomplish this?


Thanks!
