I'm wondering how to listen into the audio stream produced by an app (say iTunes for example) in my application. I am working for a client who needs this functionality in the app I'm working on (it's an audio analysis tool). Preferably this would not involve using any kind of kernel extension to accomplish this.
I am not interested in hearing about "Audio HiJack" or any closed source solutions which do this. Please remember I am trying to do this within a program I am writing.
Thanks in advance for any help you can provide.
