The sound qualit of the resulting files is excellent, and it will work in batch. -- Dotan Cohen http://bido.com http://what-is-what.com Please CC me if you want to be sure that I read your message.

That could be > another thing you can test. Yes! Installing the debian-multimedia versions of ffmpeg and mplayer did the trick. I didn't fully grok what Ron wrote (thanks!), but now I see how to `apt-cache policy ffmpeg` & `apt-cache policy mplayer` to find out what the debian-multimedia versions are and install them: aptitude install ffmpeg=5:0.5.1+svn20100411-0.0 aptitude install mplayer=1:1.0.rc2svn20100407-0.0 Now the 3gp audio files play fine. They do seem to take up a bit more CPU than mp3 or flac, but maybe that's just inherent to how they are compressed.
