compression)

| completely separate entities & is supposed to have no noticeable
degradation
| until the signal's been decompressed/compressed (by bouncing from track
to
| track) about 1000 times, or something to that effect... Imagine if this

Yamaha

| ATRAC is the codec used by Minidisc recorders. According to 'experts' it
is
| not perceptually lossless either. As far as I can remember the bitrate is
| 292kbit/s
| which is above what people are comfortable with transferring over the
| Internet.
|
| Apparently the latest generation ATRAC (seventh I think) is transparent
| to most listeners.
Yamaha MD multitrack recorders uses slightly modified ATRAC. When you use
MD from SONY, they sound much worse than MD recorded on multitrack from
Yamaha. But standard stereo mode sounds same as SONY.
