| I agree with you, there is a big difference between compression and
| compression, you can compress air, and you can compress digital data. When

| are talking digitally, we are talking bitstreams, datagrams and all that.
CD-DA is a means of compressing *ANALOG* data, not digital data.

| ATRAC is a bitwise reduction as you are stating yourself, when there's a
| way to get the original data back with a negligable or no data loss the
| it is a compression by definition.
This is my point: CD-DA sampling makes the data smaller, and you can get
the data back with negligible loss (at least that is what most people
think). By your own definition, CD-DA is a form of compression.
| ZIP is merely a bitwise reduction, it takes note of all data and try's to
| remove all redundancy, ie merely a bitwise reduction...
Well, no. ZIP transforms redundant data into a code. This is traditional
data compression. ATRAC and MP3 remove what they perceive to be
insignificant data. This is bitwise reduction.
