for relativity...A Wave file is the native, uncompressed format. I had
some trouble with the DVD drive ripping a Yes CD of mine and so I did it
on Linux. This is the comparative sizes...

$ file ive_seen_all_good_people.*
ive_seen_all_good_people.aac: MPEG ADTS, AAC, v2 LC, 44.1 kHz, stereo
ive_seen_all_good_people.mp3: Ogg data, Vorbis audio, stereo, 44100 Hz,
~128000 bps, created by: Xiph.Org libVorbis I
ive_seen_all_good_people.wav: RIFF (little-endian) data, WAVE audio,
Microsoft PCM, 16 bit, stereo 44100 Hz

Generally, an aac or mp3 is about 10% of the size of the wav file ripped
from a CD but of course, they are both lossy
