Below is output of your command:

Indeed. Note the '--enable-libmp3lame' below:

I give up.
Thanks anyway!

which package in etch can convert high-quality mp3 to low quality mp3?

Thanks! You can also convert them to WAV an then back to MP3. I would use LAME. This document might be overkill for what you need but the information you need is there (you need to find the correct LAME options). http://wiki.freaks-unidos.net/mp3-encode I wonder if your player supports variable bit rate...

I would recommend lame; it's in the multimedia repository (http://www.debian-multimedia.org/). As the default bitrate is 128k, the command line would be: lame --mp3input in.mp3 out.mp3 You might also consider CBR (constant bitrate), as some players cannot handle VBR (variable bitrate) properly. In that case the command line would be: lame --cbr --mp3input in.mp3 out.mp3 However, when transcoding, there's a caveat: all mp3 tags (ie: album, song title, artist, etc.) are lost in the process. So maybe you could write a script that first extracts all tags (mpgtx can read id3v1 id3v2 tags) and then uses them in the transcoding process. lame --mp3input --add-id3v2 --tt title --ta artist --tl album --ty year in.mp3 out.mp3 Manon. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
