Depending on the samples and quality, you may find that you need quite a bit of storage (SD card with SDIO interface). The power of the PIC to handle raw samples may be severely short to get a reasonable output. I suggest you look at the VS1003B MP3 chips that you can throw the samples at. This way, you do not need too much processing on the PIC.
another option you can evaluate is available on http://elm-chan.org/works/sd8p/report.html
