[asterisk-users] How do you convert your prompts to an asterisk-friendly format?
Hi,
I've used the shells-script at the end of this email to generate 8khz
mono wave-files for asterisk from a 144 khz recording.
The script does two things: resample & normalize the audio volume.
Anyone like to share their recommendations / scripts for doing this
conversion? I've just converted to 8khz wave, should I convert to
something else?
For the googler in the future this is my current script (which I hope to
improve):
BASEDIR=`dirname $0`
PROMPTDIRS="dir1 dir2"
for dir in ${PROMPTDIRS}
do
src=${BASEDIR}/recordings/prompts/${dir}
dst=${BASEDIR}/generated/prompts/8khz/${dir}
for i in ${src}/*.wav; do sox "$i" -V -r 8000 -c 1 -q -s \
"${dst}/$(basename "$i" .wav).wav" vol 0.8; done
normalize-audio -a -20dBFS "${dst}"/*
done

This isn't required, but you will notice a big quality difference if you run
the normalized files through Audacity and set the volume to -3
(Recommendation from the Asterisk PDF). There's most likely a way to do
this with SOX, I just haven't tried hard enough to find it. If/when you do,
please post that.
