[gentoo-user] Joiniong of mp3-files without decoding them (comletely) ???

[meino.cramer]

Hi,

 is there a tool available via Gentoo portage/emerge, whith which
 I can concatenate/join mp3-files without decoding them completely
 before or by only decoding the miliseconds before and after the
 joining point ?

 Thank you very much for any help in advance!
 Kind regards,
  Meino Cramer

You can simply cat them together:

   cat 1.mp3 2.mp3 > joined.mp3

This will result in joined.mp3 being a bit-perfect concatenation of 
1.mp3 and 2.mp3.

You can also do this with *.ogg (Ogg Vorbis audio) files.  The file 
format of mp3 and ogg and designed to make this possible.

I forgot to mention that you should strip the id3 tags from the files 
first (or else there might be some noise at the spot where the id3 tag 
of the previous file resides in players that can not handle tags in the 
middle of the stream; iPods for example.)

Hi Nikos !

 ...thanks a lot for you help ! :)
 This was my first attempt also...but what happens to the
 ID3tags? Doesn't the resulting file looks like this afterwards

 <id3tag><mp3data><id3tag><mp3data>

 ?
