Re: Not sure if its lossy...

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]
ATRAC1- DSP Type-S (2002) - [292 kbit/s]
ATRAC3plus (2003) - [256/64/48 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.

That's kinda like saying "I would say flacs are slightly better than mp3s"


(actually it's more like saying "I would say flac is slightly better than adpcm", but what the heck)
