Yes: mpg123 -s $i | sox -t raw -r 44100 -s -w -c 1 - \ -t wav -r 8000 -w -c 1 "`echo $i | sed -e 's/mp3$/wav/'`" Some thoughts: Quote all occurences of $i if youre not absolutely sure that the filenames dont contain any special characters like whitespace etc. The sox command will only work correctly if the MP3 file has a sample rate of 44100 Hertz. If this is not the case for all the files you will need some way to determine the sample rate before the conversion and give sox the actual input sample rate on the command line. Another possibility is to decode the MP3 to a temporary WAVE file and use that as the input to sox so it can determine the sample rate automatically.
