How can I convert my old .g711a files to the new format?
================================================================================
I got the best results with:
cat /some/path/dwhello.g711a | alaw2ulaw | g711conv -u > /tmp/newhello.al

I have lots of old .g711a files to convert what can I do?
================================================================================

Create a shell script (/tmp/csnd.sh) with this contents:
#!/bin/sh

OLDFILES=`ls *.g711a`
#echo $OLDFILES

for THEFILE in $OLDFILES
do
(
        echo -n "converting $THEFILE..."
        BASENAME=`basename $THEFILE .g711a`

        /bin/cat $THEFILE | alaw2ulaw | g711conv -u > $BASENAME.al
        echo "done"
)

done
###### END

then type "chmod a+x /tmp/csnd.sh" in you shell.
cd /usr/local/lib/isdn (or where your old sounds live)
/tmp/csnd.sh
Optional:
rm *.g711a (you should know what you do here :-)


How can I convert the .al files to Sun/NeXT .au/.snd/.vox files?
================================================================================

/bin/cat /some/path/old.al | sox -t raw -A -b -r 8000 - -t .au /some/path/new.snd
