Try adding -r 44100 -stereo to the mpg123 command. I haven't played
with it, but it is supposed to fix the output rate.
-r rate, --rate rate
Set sample rate (default: automatic). You may want
to change this if you need a constant bitrate inde
pended of the mpeg stream rate. mpg123 automagi
cally converts the rate. You should then combine
this with --stereo or --mono.
If you realy want to get fancy, you can add a test to see if the
conversion worked, and then delete the source file. Or if you want to
make things real easy, you could have the script play the mp3, ask you
if you want to convert, do the conversion, and delete the source file if
sox exited with error level 0.
Here is one that will put the file in your .wav directory, and delete
the mp3 file.
------ CUT HERE ------
#!/bin/bash
# mp32wav
#
WAVDIR=<your .wav directory>
if (echo $1 | grep .mp3 > /dev/null) ; then
mpg123 -b 10000 -s "$1" | \
sox -t raw -r 44100 -s -w -c2 - $WAVDIR/"$(basename $1 mp3)wav" \
&& rm -f $1
else
echo Bad mp3 file name.
fi
