Recording from the microphone

Before I start, I really have been reading the documentation and it's just confusing. I'm a linux C developer just starting out with OS X programming.

I want to write an application that takes in sound (say from a microphone), and then process it with a DSP algorithm. Something along the lines of push a button, record, and then automatically or with another button push, stop recording.

I got the CoreAudio SDK and checked out the examples. Looks like "SampleAUs" does that - but it's a "component", not an application. I don't understand the AudioUnits and HALs and AudioCodecs and how they fit together. It would seem that there should be an API for this, but I can't find it.

Thanks
Andrea
