I heard that some CD and flashplayers could play Atrac (3 and 3+ only). But mostly Minidisk players use the atrac codec. There is a big faq at minidisc.org.

ATRAC-Version (release year) - [bitrate] - {frequency respose}

ATRAC1-version 1.0 (1992) - [292 kbit/s] - {15kHz}
ATRAC1-version 2 (1994) - [292 kbit/s] - {18kHz}
ATRAC1-version 3 (1995) - [292 kbit/s] - {18kHz}
ATRAC1-version 3.5 (1996) - [292 kbit/s] - {18kHz}
ATRAC1-version 4 (1996) - [292 kbit/s] - {20kHz}
ATRAC1-version 4.5 (MD-Decks; 1996) - [292 kbit/s] - {20kHz}
ATRAC3-version 1.0 (MDLP) (2000) - [132/105/66 kbit/s]
ATRAC1- DSP Type-R (2001) - [292 kbit/s]

Sure. Would be nice if we could gather samples of all the different versions. Should we keep that at imageshack? the maximum filesize of png files is 100kb here. I would say png are slightly better than gifs.
