That´s nice Niels. I know that sox can play with "play" command. I didn't try hard, but do you know how to check sound files in Emacs with dired style, like a normal file manneger that you can playu the files? 2010/7/6 Niels Mayer <nielsmayer@xxxxxxxxx>: > FYI: http://space.twc.de/~stefan/gst123.php is a nice command-line > audio/video file-playing utility that should be part of Fedora or > PlanetCCRMA.
