I ran across this nice board.. http://www.ghielectronics.com/details.php?id=1&sid=2
It is the fat protocol on a chip allowing 4 open files to write to 1t once, there is a bored for writing to SD cards.
has anyone seen or worked with this? It looks easy to use. Also how do i go about using the I2C protocol on the arduino?
I am currently building an amplifier using tripath chipsets that I am going to control with the adruino and if i can I want to open audio files for playback and what not.
Also, while I am at it. Has anyone done IR remote controll? i think the sony protocol would be nice to use, that way i can use a universal remote to control it. 
also, is it possible to sample the audio stream then using the PWM and a capacitor to ground recreate the signal so i can control mixing of channels and volume in the arduino?
Yay first post! I remember when i built yabb once, ah the memories
