[Asterisk-Users] Asterisk 1.2.7/9.1 mp3 volume is good, wav file of same volume are too loud!
Ok, Here's another bizarre one (no strange curve balls to throw this time :P). I have several mp3 files of some easy listening music that I pulled off some CDs we have. They sounds fine and are at a nice volume level. When I run this script I wrote: (I run it by doing ./script < filename) mpg123 -s --rate 44100 --mono $1.mp3 > $1.raw sox -r 44100 -w -s -c 1 $1.raw -r 8000 -c 1 $1.wav rm $1.raw The wav files comes out with the same volume (I checked using a program called goldwave)... and infact if I play it on my laptop it sounds the same and the VU meters show the same volume characteristics....however, when I place someone on hold, the music becomes deafening.. ok maybe not that bad, but it's very much louder to the point of almost being too loud. Is there something volume wise different about the internal mp3 and wav players?
