Play WAV files on a micro SD card using Atmega8 (2/2)

This is a tiny SD card module. It has micro SD card slot, FT232RL and Atmega8. I ported a FAT file system module. It's "Petit FAT File System Module" from http://elm-chan.org/fsw/ff/00index_p.html This is great. And then I tried to create a sound with WAV file on the micro SD card. The board (and the firmware) can play 8KHz(8bits/16bits) sampling formats now. The song is a demo song for KORG SV-1. It's from http://www.korg.co.jp/Product/Synthesizer/SV-1/ The keyboard is the best sounds ever seen.
