Simple MAC OS X Application to Capture Sound From Microphone

I need an OS X application based on OS X core audio that captures sound from microphone into raw PCM audio buffers. This application is for tutorial purposes only.

It has to illustrate the usage of OS X core audio api, the callback function and buffers.

It has to do the following:

- Enumerates all input devices (microphones) attached to the computer in a drop-down list.

- The user selects an input device and presses a button "Rec".

- The application starts capturing from the microphone. The raw PCM samples must be received in a callback function then saved to a wav file (optionally) or discarded.

- The user must be able to specify the buffer length in milliseconds (not in bytes).

Must be compatible with MAC OS 10.6 and above. Latest Xcode 6 has to be used.
