Advice on splitting up an mp3 album

I was looking for some advice on how to extract the individual tracks for some albums that have been ripped and encoded as one complete mp3 file?

The problem is of course that these files no longer have a cue sheet indicating the track lenghts.

So I was wondering what people's experience and/or advise on how to go about splitting to get the most  accurate (within reason) timing and integrity of the individual tracks.

The best I have come up with so far is, if I'm lucky, to find the cue sheet through a program such as CueMaster and then split the one mp3 file with musiCutter based on that cue sheet.

The problem with this is that if the mp3 has not been properly ripped (which seems most of the time) then there is usually some extra silence, or lack of, at the start of the mp3 and hence all the tracks are cut with that extra offset. Any ideas without manually setting each track or cutting/adding silence to the start of the mp3?

Thanks

heh yeah, full album mp3 is really annoying.
seek through the file in your favorite player and note the playtimes of the track gaps.
then use mp3trim to cut off the respective beginning and end for every track (mp3trim has nice cut feature with preview). I did that once, works ok (no re-encoding) but I will never DL such a gargantuan mp3 again

Bad thing is you need mp3trim PRO for such large files, there might be other software that can do the same (cut mp3s lossless) but I havent used any other.

edit: hmm maybe you did someting similar already? I cant think of a more "accurate way" without the orignal cue from the rip, just trust your feeling there. I have seen CDs that were horrible cut (Black Sabbath - Sabotage, between track 2&3 for example, and some of the nnewer Type O Negative), so you problably wont do it much worse than the enginieer....

WBIAS will extract timestamps from winamp and generate a commandline for BeSplit.


EDIT :
vbr is obviously supported, and vbrtag headers are being reconstructed correctly.

Thought I'd heard that mp3trim didn't always get the file formats right, not a good tool for this in any case

mp3 direct cut

You can see and listen, should be easy enough to get the splits plenty close

Great - Thanks

Does anyone know if mp3directcut or mp3trim work with vbr mp3s?
and any after-effects? (ie timing screwed up, etc)

mp3 direct cut works with VBR (but keep the original until you check out the timing to be sure).

It also has a silence detection feature, I think, which can help when you've lost the CUE file. It also works with CUE files and can save CUE files.

The VBR header will be screwed, so use MP3/Tag Studio to fix it.

If you didn't create the file yourself, it's possible that the file is an AlbumWrap file. Go here to download the free extractor.

In my experience, it messes up the timing (--ape MP3s). I'd advise against mp3 direct cut for VBR. WBIAS (as recommended by DSPguru) may work better; I took the long route with Cue->musiCutter->Fix VBR.

Sometimes Album Wrap can't extract albums even if they are wrapped, in those cases you can try Alba Extractor (http://alba.sourceforge.net).
