Converting Sound Files With Asterisk

This shell script will convert file formats using Asterisk. As an example, it converts the Enswitch sound files from g722 to gsm:

cd /opt/enswitch/current/sounds/en/
for oldfile in `find . -name "*.g722"` do

newfile=`echo $oldfile | sed 's/g722/gsm/'`

asterisk -rx "file convert $oldfile $newfile"

done
