I did find the -rawaudio parameter and it worked after I set it up with : mplayer -quiet -rawaudio samplesize=1:channels=1:rate=8000:bitrate=64000 \ -demuxer rawaudio \ rawfile.ub The bitrate=64000 parameter appears to not really be necessary if you specify the 8,000-sample rate. The seek commands using the arrow keys work but the message showing percentage of the file always shows 0%. Again, my thanks to both responders for helping to clear up the confusion.
