asterisk users - Jan 2007 - MusicOnHold Files

I was just wondering what you all are doing for music on hold files
for best quality.  I am not much of an expert on sound rates, bits,
stereo, mono, tracks, and all that jazz.  Currently I am taking music
from a CD (our campus jazz band has recorded a CD), converting to WAV,
using Audacity to convert the stereo tracks into mono, drop the gain
to -15db, then I use sox to convert to GSM and 8 bit (by typing #>
/usr/bin/sox file1.wav -r 8000 -c1 file2.gsm resample -ql )

The audio while on hold is OK.  I wonder if there is a way to get
better audio.  I noticed that asteriskguru.com has a audio conversion
on their website.

Thanks for any help.

Since telephones are so lo-fi, is there any reason to invest a lot of energy 
in hi-fi hold music? .wav is uncompressed and lossless, so it should sound 
better than .gsm which is a lossy format. But I doubt anyone can really tell 
the difference on a telephone. anyway, how long are you leaving your callers 
on hold? :)
