Geoff - If you use the -s switch in mpg123 to direct output to stdout, won't that make a "raw" file instead of a "wav" file? I wonder if the absence of the wav header is what is giving Brent's files fits in Windows? I have not tried the -s switch yet, so I really do not know what it will do. The trouble is, if you make a raw file that way, you no longer have information about its sampling rate and sample size etc - except from the mpg123 runtime display. Chuck. My web site is http://www.mhonline.net/~chuckh Winter will ask us what we did all summer.
