Well, I think we're calling it normalize cause that name sorta stuck.
We are in fact just changing the volume of it, and using sox, cause as
you say, it supports more formats. Normalize just didn't do what we
wanted it to, and didn't support the format we were using, so sox seemed
like a much better idea for the time being.

It basically sends the voicemail attachment through sox to increase (or
decrease) the volume of the message as need be, and then sends the
normalized file to the user.
You aren't normalizing the audio, you are just adjusting the volume. If
you are going to go to the work of using an external app, why not use
normalize so it truly is normalized and doesn't introduce problems when
audio comes from different sources and therefore needs different audio
adjustments.
Now the trouble with normalize is that it doesn't support very many
formats. I think it supports PCM wav and mp3 only. At least sox does
have better format support.
