Hi, 
I'm writing an MacOSX app that is able to capture audio from speaker and save the audio file to disk in wav or whatever format for further replay.
I googled a lot and found out that Jack might help me to do this kind of thing.
Is there any tutorials for this? Should I download JackOSX? I have cloned jack2 source code and successfully build example-clients/capture_client.c .
Could you give me some guide?
Thank you very much
