Re: Zeddy audio playing now a reality!

Moggy, stereo is indeed possible but at reduced samplerate. I don't remember if shuffling data from the card was a bottleneck or not.

Re: Zeddy Audio Jukebox

There is a program to convert audio to the format needed by this player. Have a look at the description at guthub, it tells most you would need to know.

Re: Zeddy plays guitar.

Moggy, forget about 16-bit audio. But it WOULD be possible to do 8-bit stereo... And possibly logarithmic u-law audio to get better/different sound quality.
