Hi Brent: I see that you've already been given the command to write a WAV file from MPG123. I might just point out that (A) Not all programs will pipe to standard output without being asked, and (B) there's vertually no need to ever pipe to arecord, as you could redirect outjput to a file. For example: mpg123 -s filename.mp3 |arecord -m filename.wav would have done what you wanted, since the -s tells it to write to standard output (stdout). But it's far more efficient to do this: mpg123 -s filename.mp3 >filename.wav This uses the shell to redirect standard output to a file. You could use 2 greaterthans to append rather than to rewrite. Of course, this is a bad example since MPG123 will do it itself with -w which I recommend above both of the above. Geoff. -- Geoff Shang <gshang10 at scu.edu.au> ICQ number 43634701
