I think this poster may be confused by the '.wav' label applied to the
ripped music file. To answer that question, the data on a red book
cd is a .wav format already, with no compression pre-applied to what
is basicly a 16 bit definition digital audio data stream, and applied
with relatively little regard for the niceties of a real filesystem.
Burning the .wav files that result from ripping with cdparanoia
should normally make a disk that will play in your "ancient" player.

The mp3 format is a patented, commercially available compression
method that can shrink a 40 megabyte song down to 4 or 5 megs of
data. And it sounds pretty close to the original sonicly, with what
I'd describe as a bit of blurring on transient sounds.

Because mp3 is patented, and not free, licenses going for $15K-$25 to
use it, the free "ogg" encoder was developed, and which uses none of
the patented methods that the mp3 format uses. The compression
achieved is quite comparable to that achieved by the mp3 encoders.

But those of us with what we like to call "golden ears", will pick the
ogg version as the better sounding version of a piece of music a
surprisingly large percentage of the time. I've tried both, and its
the ogg format thats better here, pretty close to 100% of the time.

Note that since either method is a lossy method in that some
information the ear doesn't use all that much of is thrown away, but
because the two methods differ in what they throw away, re-encoding
an mp3 to an ogg, or vice-versa, will result in some pretty obvious
distortions, so one must start with the original material to make
either format of file. Those files won't play on the regular audio
cd player of course as it hasn't the required brains to uncompress
the data back to an approximation of the original.

I hope this clarifies things a bit for the original poster.
