Convert WAV file to Asterisk playable format

Linux

Install SOX:

yum install sox or apt-get install sox

If file1.wav is any WAV file, then executing this command:

/usr/bin/sox file1.wav -r 8000 -c 1 -s -w file2.wav resample -ql

you will get Asterisk playable WAV file: file2.wav

Use following script if you need to convert multiple files:

#!/bin/bash

ls >/tmp/a
for i in `cat /tmp/a`; do
   /root/folder_with_Voices/convert_mp3wav2astwav.sh $i /root/folder_with_Voices/rdy/$i
done
