If you wanted to hijack the audio from a Chrome window, what API would you use. I want it to be only the sound for a specific app like (Chrome). What I want to do is to modify the sound level and optionally record it based on a schedule. I just learning OSX programming and using the NBR Advanced Mac OSX guide, but haven't found anything that covers this yet. Google searches haven't yielded any results like a tutorial, but it looks like OSX offers some of the same APIs as iOS does. Thanks for any insight.
