well with mine and rangers too im sure,they were already converted from mp3 to wav and also reformatted to ah2
22hz 8 bit mono,so unless you started from a new mp3 recording theres no need to covert to wav,its already been done
maybe when you conerted it with audacity it may have changed the speed or corrupted the file,im not sure there,ranger would
probly know more about that than me.
