Here is some kind of version history of the Atrac codec used in MiniDisc devices.
(Which ATRAC chips are in which MD units? minidisk.org faq, version table) ATRAC-Version (release year) - [bitrate] - {frequency response} 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] - {20kHz} ATRAC1- DSP Type-S (2002) - [292 kbit/s] ATRAC3plus (2003) - [256/64/48 kbit/s] - {20kHz/?/?} Atrac3 (MD-LP) I found the codec at minidisc.org. Samples also taken from there. Quote:

Re: MiniDisc (Atrac) Spectral and Frequency analyses.
If you send me one wav file via a free file sharing site I'll take a look at the spectral and give you my thoughts. Shit, i'll even post it up on the forum for mods to chime in.

Re: MiniDisc (Atrac) Spectral and Frequency analyses.
It's a shame this continues to keep me from uploading ANY Hi-MD Minidisc Master recordings here.
But i constantly see "officially" released material shared here and NOT Banned !!! No members have liked this post.
