I forgot to mention:
CDs store the information 1:1, so no compression from the viewpoint of
incoming and stored information. Stop, it becomes worse: The CD stores also
a CRC after each chunk of data which is redundant to the information. This
means that there is the contrary of compression stored on the CD, more data
than necessary to listen to music but enough to restore if reading wasn't
successful. How can we write this compression ratio down? 1:0.98 or so
should be fine... :-)
