[opensuse] mp3 layer 3 -> mp3 layer 2
I have 89 files that are MP3 layer 3 that I want to convert to MP3 layer 2 because this dumb player in my car won't recognize layer 3. Any suggestions on the best way to do this with a Linux tool that can be driven by the command line?

Well there is sox , but its not clear it will convert from 3 to 2, as it does not address layer at all, at least not under that term. Isn't the primary difference a fixed bitrate in mp2? -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

did you try lame? the man page is a mess, but the product is aimed at any mp3 job? jdd -- http://www.dodin.net Votez pour nous, merci - vote for us, thanks :-) http://musique.sfrjeunestalents.fr/artiste/Magic-Alliance/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

mencoder or transcode. You can wrote a simple Bash script with a FOR loop to automate it. However, as the say goes: "lossy to lossy, it will sound like ass (arse)." Charles -- DPRINTK("doing direct send\n"); /* @@@ well, this doesn't work anyway */ linux-2.6.6/drivers/atm/eni.c

You are confusing "mp3". mp3 == MPEG 1 Layer 3 (or, at your option, also MPEG 2 L3 or MPEG 2.5 L3) mp2 == MPEG 1 Layer 2 Decode using lame, mplayer, mpg123 or whatever, encode using twolame. -`J' -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

No, Layer 3 has improvements like a bit reservoir, huffman coding for the samples, different sized subband emulation, a 36 point idct on top of the subbands. It's pretty much a mess, they threw every algorithm in they could find. That's what makes mp3 much more vulnerable to bad encoder settings.
