Mac OS sound/data development

We are looking for assistance in the development of our Mac OS client SW. We need someone to develop the code in Cocoa/C++ to do the following:

1. Get sound from microphone on a Mac (OSX or Intel-based) which defaults to 44100 hz and convert it to RAW in various formats (8000hz,11000hz,22050hz,etc.)

2. Convert RAW packets of various formats (if necessary) and send to the speaker for playback.

Currently we have been unable to convert the 44100hz RAW of Mac into other formats (#1 above). We have also been unable to send these packets in any format to the speaker of the Mac computer for playback.

We have already attempted to convert to WAV and play them, but since this is "streamed" data, the sound gets a clicking (probably due to the header of the WAV created).

Taidot: C-ohjelmointi, Cocoa
