Recording audio on Mac

I am developing an application which access my audio input device and record audio from my microphone. Here when i am pressing START button it have to record audio from microphone and have to stop recording when pr开发者_JAVA技巧essing STOP button.

My device is Lynx-AES16 and i got driver from there site.

In windows i am accessing the machine(Lynx) by using direct-show SDK(Graph edit).  Is there any similar tool  like direct-show is available. I checked with AUAudio and IOkit but didnt understood that much.

Can anyone provide some sample or some useful links. Apple link is not good for a starter

Look at the CoreAudio sample code at developer.apple.com. There is plenty of useful code there.

In particular look at the RecordAudioToFile example.
