I don't mean to criticize any of the conversion suggestions, and I'm not an
audio expert, but I recall reading some time ago that such conversions might
produce less than satisfactory results.

I believe that WMA files are compressed from the .wav (44.1Khz stereo digital
audio) files produced from ripping the CD tracks. In this process, some
(generally inaudible) information is removed such that when uncompressed back
to .wav format the sound is still pretty good, but the overall quality is
somewhat less. Most people wouldn't care about this loss.

The problem arises when the second generation audio tracks, WMA files when
uncompressed, are then re-compressed using a different method such as with
ogg-vorbis. It also removes some information, but in a different way, so an
already degraded sound track can be degraded still further. I have read that
some people can hear the quality difference from the first, to second, then
third generation audio.

Given this, my approach would be to get the codec libraries required to play
the WMA files as you have them.
