MiniDisc (Atrac) Spectral and Frequency analyses.
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.

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.

Need opinions if these are LPCM mode mini disc recordings. I believe them to be LPCM and not ATRAC.

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.
