The problem with MP3 encoding is that it will often perform 
extraordinarily badly when listening to CW.  You only have to listen to 
the readily downloadable practice morse sessions from W1AW to see what I 
mean.  They will either sound fine or awful depending on the codec that 
you have installed into Windows Media Player.  

You can read more about this at:

Paradoxically, the more recent codecs are a lot worse than slightly older 
ones.  The problem is that some codecs simply cannot handle continuous 
tones of one frequency - the MP3 encoding just falls apart.

I would suggest that in order to hear what the DSP unit sounds like, you 
need something that's as close to the original as possible.  MP3 + CW is a 
combination that will introduce far too many artifacts into the resulting 
output.  The simplest solution is just to use WAV files and ZIP them up 
-- WAV files compress very well.  Surely most people have got a ZIP 
utility these days?
