I have been in the process of developing the WavePro shield; a WAV playing shield for the Arduino / ChipKit boards based around the dsPIC33FJ128GP802 chip.
It allows you to play WAV files at up to 48000Hz, 16 bit stereo, and to record at up to 16000Hz 16 bit stereo.
The dsPIC access the SD card onboard directly, so the host microcontroller doesn't need to spend time reading the WAV data, decoding it, and sending it to the DAC - all that is handled for you.
Now, I have reached a point where I am looking for someone (who doesn't know the internals of the board) to try one out (for free) and help me break it.
The library I am developing to run with it is intended to work on both the Arduino and the ChipKit without changes, so someone who knows a little about ChipKit libraries would be a help (but not essential).
Having some knowledge of the SPI and DSPI libraries, however, would be a real benefit.
Oh, and you'll need some way of uploading new versions of the firmware to the dsPIC. That means you'll need a pickit2 or pickit3 or similar hardware programmer at your disposal.
If you're interested, drop me a line (in a PM) and let me know why you think you should have a free WavePro shield.
