write small sound files to MMC card

I use a 18f8720 at 6Mhz and the latest compiler from version 3 (3.249?)
Sofar I have a LCD and I can write and read blocks(512byte) to and from MMC card(32MB). Serial to pc(38400baud) is also set up.

I need to write small soundfiles few seconds each (mp3,wav) on the MMC card, through serial pc connection.

Do I need fat16/32?
I assume wav will be easier later on when sending data to the Futurlec.com mini mp3 from ETT?

Any links or ideas to proceed?

You do not need to use FAT16 or FAT32 unless you want to be able to remove the card and have it read by a PC. You will however have to manage your own file structures.

You might find it quicker and easier to use a FAT rather than reinvent the wheel. If you are interested check out the file systems on my site.
