How to get audio data from a Macbook microphone?

Question

I want to write a little audio processing program, and I need a way to get audio input from a microphone on a Macbook.

Polling a buffer? Notifications? What class / structure should I know about?

Answer 1

One of the easiest ways is to queue the audio. its rather abstract, with an honest dock and examples, easier than delving into the audio devices and the depths of the main sound.
