script for concatenating audio tracks?

[Gentree]

Hi,

Anyone have an automatic way of packing audio tracks ?

Many albums, especially live recordings get stupidly split up with aritificial breaks when remastered for CD release . I hate this, it often ruins the music and the enjoyment of listening to it.

Can anyone suggest a script to pack a series of individual tracks as mp3 into one continuous file.

I imagine uncompressing with mpg123 , stringing the files to gether and recompressing with mp3 or ogg.

I dont care if there is a slight loss of quality as long as I dont have 2s gaps in the cheering between tracks.

Thanks for any tips.

TIA, Gentree.

Have you tried `cat'? I know it works with some movie files, but I haven't tried it on mp3s. You could try something like:

Is there a reason you can't use an audio player with gapless playback? (Maybe this is for a portable mp3 player that doesn't have that option?).

According to this mailing-list posting, xmms can play ogg files without gaps in-between. The posting also says that the windows program foobar2000 can play mp3 files gaplessly. I had no problem installing foobar2000 under wine and it seems to work well (though I've never used the gapless playback feature).

It not that anything has changed , you just got lucky this time. I suggest you tarball the whole ~/.wine installation because next time you touch it the chances are it will be broken. Also do a quickpkg wine.

That way at least you should be able to recreate what you have now.

Wine is impressive when it works but it rarely lasts long. There were some important regreassions again in 0.9.4.

Stick with what you've got and back it all up well.

there is also xmms-crossfade. if i am not mistaken it offers an intelligent gap-removal routine on the fly (read: while playing). it basically reads the first few bytes of the next song while the current is still playing. and it then tries to concatenate the sound ouput.. that basically means.. eliminating the gap. just get sure to disable the actual crossfade functionality.

you can then use the file writer to create a master for cd. but for mastering audio cds (i havnt done that under linux) but any decent burn program should be able to give an option to set the track gap. but then again.. im not sure if mastering audio cds was your main goal.

recording to a CD without 2 second gaps requires DAO mode. Although you could do it with 1 big track as well, I don't think you would be able to skip tracks easily. cdrdao is one way to record this way, but you probably want some type of front end for it, lots of people use k3b

[Gentree]

That's the whole bloody problem , there are no tracks , this is one continuous recording that has been artificially chopped up into "tracks" for CD release.

As I posted above I have solved that to the best extent I can without getting into sound editting to repair the damage done by the publisher to the original recorded work.

I never even mentioned recording to CD

my bad ... I saw the "2 seconds" part and immediately thought about the 2 sec pre-gap on most CD's

sox utility appears to be able to do this via the "silence" option, although the man page is slightly confusing.

try something like
sox <infile> <outfile> silence 0 -1 0:59 2%
to remove the first silence gap it finds in the first 59 minutes. change -1 to -2 for second gap, if I read it correctly. This looks like it would be useful in making sure mp3 files don't have any silence in them before burning a live cd, will check this out myself when I get a chance.

thx , Ill make a note. Let us know how you get on.

I noticed in portage there is a program called mp3wrap. Have you tried that?
