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.
