How to capture native OSX audio data?

Question

I'm using XCode/Objective-C to create a hardware LED music visualizer that lights up according to system audio.

Right now I am using SoundFlower to reroute the system sound card input into AVRecorder, but I am unable to capture individual buffer channels, and other users will have to install SoundFlower.

Is there another way (a framework, preferably) to accomplish this without using SoundFlower?

Answer 1

I would suggest using the Jack framework instead. Here is a tutorial on installing and routing the jack driver.
