From the Wikipedia article:
Audio CDs
Audio CDs do not use WAV as their sound format, using instead Red Book audio. The commonality is that both audio CDs and WAV files have the audio data encoded in PCM. WAV is a data file format for a computer to use that cannot be understood by CD players directly. To record WAV files to an Audio CD the file headers must be stripped and the remaining PCM data written directly to the disc as individual tracks with zero-padding added to match the CD's sector size. In order for a WAV file to be able to be burned to a CD with most burners it should be in the 44100 Hz, 16-bit stereo format.
So there are no WAV files on your CD, but whether that warrants a 1-in-4 difference in size I do not know.

Perhaps there are more appropriate forums to ask this question, which does not really has much Perl content?

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
