The standard Asterisk prompts are already available in a wide variety of 
encodings.

Try "googling" for "asterisk convert mp3 to wav"

Some will suggest to use Asterisk. Besides appearing to use a sledgehammer 
for a fly-swatter, I don't like using a mission critical resource when 
there are better alternatives like sox -- especially for scripting.

g729 will be a bit of a bitch, however.

I cobbled up a script to use mpg123 (to convert from MP3 to WAV), sox, 
and normalize.
