Full Version: Gapless MP3 to CD for Live Albums

When burning mp3's of a live (or Dark Side of the Moon style) recording to CD there is usually an audible disturbance between the tracks. Most of what I have seen on this topic requires the use of an audio editor to fix this.

I noticed that Foobar has the option on conversions to output to a single file. However, I was looking for an easy way to cut this file up.

There is a freeware cue sheet editor Cuemaster which will produce a cue sheet if you drop the individual mp3 tracks on it. Rather than producing a correct cue sheet for the individual mp3's it creates a cuesheet that will divide the full album wav file that Foobar2000 can produce. The cuesheet will need a bit of fixing. Change the file extension from .mp3 to .wav and the file designator from MP3 to WAVE. Also, delete the pregap line at the start of the cue sheet as some programs will choke when they see a 0 second pregap.

Cuemaster does not do a perfect job. There is a gradual drift that adds up to indexes being about 2 seconds late by the last track. When burning a live album with applause between the music, you might not notice the difference. The cue sheet can be tested by using it to play the wav file in Foobar2000. If it seems off, it can be fixed using the EAC audio editor.

When you are done, burn the cue/wav in EAC or Burrrn. You may need to to additional editing for other programs.

If any of you have other efficient ways to do this, I would like to hear about it.

Burn directly with foobar. It'll produce a perfectly gapless cd.

Just burn from foobar? Has anyone else tried this, cause it sounds too good to be true.

If the files were gapless in foobar2000 before being burnt to disc, then yes, burning with foobar2000 will give you nice results. (If the files weren't gapless, then you'd have to try getting help from gapkilling plugins and the like.)

You need to have the "foo_burninator" Audio CD Writer plugin installed, which requires that you have Nero installed.

The recommended method for getting gapless MP3s is to simply use a recent version of LAME to encode your files. The --nogap option will be unnecessary.

All I do to create a gapless cd from mp3s is simply convert the mp3 files to WAV with foobar's diskwriter. The individual wav files are gapless just like the originals, so I don't see why there would be a reason to squish them all to one file. Drag the wav files into Nero, and change the pause to 0 seconds on all but track 1.

I am aware that the newer versions of Lame solve the problem. However, Lame is not the only encoder in use, even if it is the best. Some of us may have used something else in the past which causes the problem.
alkabrecka
Sorry, I thought that using lame was just implied in the original question. My method only works with lame. I don't think there's any sure fire way to get a perfect gapless file from other mp3 encoders besides converting to wav and using an audio editor to manually cut the silence from the beginning and end of each file.
kjoonlee
If your files aren't gapless to start with, try using a gapkilling plugin in your audio program. foo_dsp_nogaps and foo_dsp_continuator for foobar2000 come to mind.

If you can get them to play gaplessly using the DSP plugins, then you can use them to convert to gapless wav files (by selecting "Use DSP" in the Diskwriter settings), or if you use foo_burninator, to gapless CDs. (Choose "Use DSP" in the Audio CD writer settings for this.)

In order to burn gapless wav files properly using Nero, you need to select all the tracks except track 1, right-click, choose Properties, and make sure Pause is set to 0, not 2.

properly?
Nero will kill the last samples of every track to round the last sector. A little part of your work deleting the silences will be killed by Nero.

There are programs like Feurio, Wavelab, Samplitude that can burn those tracks "really" properly.
alkabrecka
if you use cooledit pro, you have the option of editing the wav by the 75fps audio cd standard. Just right-click the big time display at the bottom and a menu will pop up. This way nero won't alter the finished edit. I'm sure other audio editors have this ability too.

I tried to do some track end fixing in Feurio and was not successful. Using the method outlined as the start of the thread I had a perfect result on the first try in about 5 minutes with a 32 track CD that mixed no gap tracks with gap tracks. How long would it take to adjust the ends of 32 tracks?

The drift problem that I had notice did not manifest itself on this project. It may be that retagging using Foobar2000 did the trick. Feurio reports some MP3's as having an extra 227 bytes at the end which may have been confusing Cuemaster. Foobar2000 strips that out.

Anyway, this works like a charm, uses free software, is fast, and takes almost no talent. If you have to do something to tweak the layout, changing the cue sheet using EAC is a lot easier than trying to edit the track itself.

Maybe because you didn't decompress the tracks.
The Track Editor viewer in last versions was modified and it's not "accurate" with MP3 tracks.

Once decompressed it's easy and I've done it a lot of times.
Just select "Do not insert pauses between tracks - round track markers" Setting for the project (this is not the default setting when installed). This is the setting that most burning programs lack and needed to correctly burn MP3 tracks without silences.
Then use "Set start position" and "Set end position" with the help of the zoom in Feurio Track Editor.
The burner disc will contain exactly what you hear in Track Editor or Wave Player.

using the program mp3trim, "auto cut digital silence"
burning with nero using the wizard, select all -to-be burned-tracks (except the 1st) and properties, and change silence between tracks from 2 (default) to 0 seconds.

should do it

@ minix & sigmund

Actually, the tracks that have been giving me a problem do not have any intended silence in them. That is why decompressing them to a single wav file for the album works. I guess what you are removing in the editor is the difference between where the music ends and the nearest 588 sample mark.

I have no doubt that there is a way to edit out the disturbance Feurio, athought just setting the round track markers does not do it by itself.. I just think that I found an easier way to get a good result. There are lots of ways to get the same end result. YOu might want to try this and see if it works.

Minix, I know from your posts that you really like Feurio a lot. While it has a very good combination of features, it kind of drives me nuts with all the warning dialogs. Many can be disabled, but not all. At any rate it really could drive a first time user to distraction. Also, the program does not formally support my drive, so some function is lost and I get even more warning dialogs. Even so, I keep Feurio around because sometimes it can be handy. I don't have to love every tool in my box. At least it is not as buggy as a bed in a cheap hotel.

Its kind of like my love/hate relationship with Widoze XP.
