If the file is a "wav," it should look something like this:

 	-t2::sedwards:~$ file example.wav
 	example.wav: RIFF (little-endian) data, WAVE audio, Microsoft\
 		PCM, 16 bit, mono 8000 Hz

Also, just in case you trip over this, you pass a file name to Asterisk, 
not a file type -- the bit after the period. Asterisk chooses the "best" 
type from files of the same name based on the codecs available to the 
channel.
