[Asterisk-Users] Voicemail volume adjustment

[William Piper]

Here is a bash script that will increase volume of all wav files in a
directory:
-----------------------
#!/bin/bash
for i in *.wav; do
val=${i%.wav}
echo converting $val.wav
sox $i -v 2 $I $val.wav
done
------------------------
-v 2 will increase the volume 2 times.

Here is a patch that someone else wrote, I haven't tested it or used it.

Enjoy,
