Hi,
> The guitarist in my band uses a Yamaha MD8S to record all our stuff. It
compresses 1 CD's worth of audio down to about 150MB (about 5x compression)
by removing details from the signals that we can't hear (so I assume it
works in much the same way as MP3). It records up to 8 tracks at once as
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
"ATrack" codec was made available for personal computer use, & what Yamaha
would want to do to anyone who worked out how to do it...
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.
I don't see why this codec can't be implemented on a PC, but I'm quite
sure Sony has a million and a half patents on it.
