[Asterisk-Users] Digium TheVoice recordings' sound terrible

Benjamin,

Don't know if this helps you or not, but this is taken right from
Jtodd's wiki page.

**my disclaimer** Might want to backup your sounds before doing this though.

#!/bin/sh 
 tmpfile=/tmp/rescale$$.wav 
 for i in *.wav; do  
   scale=$(sox $i /tmp/foo.wav stat -v 2>&1) 
   if [ $scale != "1.000" ]; then 
     echo -n "Rescale $i..." 
     cp $i $tmpfile 
     sox $tmpfile -v $scale $i 
     echo 
   fi 
 done

Hope this helps,
