Try lossless compression: (eg using zip) 
$ ls -l crazy.wav 
50685644 2009-09-18 17:18 crazy.wav
$ zip crazy.zip crazy.wav 
  adding: crazy.wav (deflated 8%)
ls -l crazy.zip 
46434455 2009-09-30 11:34 crazy.zip

  • Need a compression system suitable for audio.

  • (Could use a lossy compression that tricks the ear).
    $ BladeEnc  crazy.wav  crazy.mp3
Encoding:  crazy.wav
Input:     44.1 kHz, 16 bit, stereo.
Output:    128 kBit, stereo.
Completed. Encoding time: 00:00:18 (15.96X)
$ ls -l crazy.mp3

    How does it work ?
