Please help me......
How can i extract audio tracks from a live-cd without gaps among one and the other? And expecially, how can i burn them with a result just like the original........?
I extract the tracks to encrease them audio quality, but don't know how to burn a good resilt cd.
Thanks you all.............

..............? WHAT DO YOU MEAN.....?

He's being flippant. He means why do you type in upper case (capitals)?

Your CD burning program should enable you to burn the tracks without the standard 2 second gap. Nero and Easy CD Creator certainly have this ability.

What CD burning program are you using?

Try EAC

You seem to be asking two separate questions. At least, ripping and burning are separate processes. With ripping (extracting the .wav file from cd to your hard drive) I don't know of any process or program that adds two-second "gaps" of silence at the end of tracks. This only happens when burning. Make sure you don't use "track-at-once" mode when burning, use the "disc-at-once" mode. In fact, do this whether or not you're burning a live cd... it's just better, unless you want to make the product cd longer than the original from which it was copied. The two-second gap thing is largely a holdover from the early days of cd audio, when players didn't have the precision to start at an *exact* beginning of a track.

From the mention of live CD are you trying to split one continuous track into several smaller ones and then burn the CD so it will play exactly like the original, but with the capability of jumping from point to point within the track ?

Feurio handles this very easily, the basic process is to copy the CD to a project, open the wave editor and use split track(linked) to chop it up into the sections you wish. Go back to the project and edit the track names to suit and then burn.

Haven't used EAC in a while, but I beleive you can split the track and then use an option to set the markers to frame boundaries. This seems to be the same thing as linking in Feurio.

i can set EasyCD to all 0 secs gap ... but Nero tells me that the first gap, after the 1st song, must be of 2 secs! any idea of why?

The first gap is before first track not after.

no, i get a 2 secs pause when the first song finishes

Are you sure, that the gap is added by Nero? It can be original gap added by ripper. Eac by default and AFAIK cdex always adds gaps to the and of the file.
For me the gaps I choose in Nero are always before the track.
If you want you can select tracks 2-last, and select to crossfade with previous track at length 0 seconds.

I've noticed that when you rip a live cd, there are a little bit of silence at the end and the start of each track (you can see it using an audio editor like Cool Edit or Sound Forge).
So, when the cd is ripped to wav I must manually delete this silence and then burn with Nero, setting 0 sec. of pause.
>... but Nero tells me that the first gap, after the 1st song, must be of 2 secs! any idea of why?
Never mind about the first 2 sec gap added by Nero. I'm sure this is before the first track and not between 1st and 2nd.

Mp3 will also add unwanted gaps to live cds...even after you decode back to wav. (Correct me if I'm wrong)

The best way to get it done is to rip the CD as one single wav with a CUE sheet holding the track information. Easiest (and surest) the rip can be done with EAC, writing can be done with most burning software that supports CUE sheets (Nero, Feurio, EAC, winCDR etc.)

Thank you GeSomeone. Do you know if it's possible to use EAC for extracting one single wav + CUE sheet and then encode into several mp3s starting from this single wav, in automated mode using this CUE sheet file?

There shouldn't be any silence in the ripped tracks (from CD) if the original has no gaps.
If there is silence, then the ripper is flawed.

Why don't people use Feurio?
You don't have to care if the WAV is cut on sector boundaries or not.
Of course, if the length of the WAV is not multiple of 588 samples, Nero will add silences between tracks.

With Feurio you only have to choose "Do not insert pauses between tracks - round track markers" in the Settings of the project.
You can hear the result before burning... You can also extract the whole disc to one only WAV, so it's absolutely impossible to insert silences if they aren't in the original disc...
It's simply better than Nero in everything...

I use EAC and done some tests with original live cds and got the same problem. I think the problem is not in the cds (if originals) or software extractor.
Maybe the problem is in the cd-rom that split the tracks on the fly durin ripping process.

So, I think the best way to rip without any gaps, is using some cda extractor that extracts a single wav, than split the files using a sort of CUE sheets.

Can someone tell me if there is a software that does this?

Of course, if the reader is defective maybe it can rip uncorrectly...
But with modern drives I'd blame the software before the hardware.
I've never had that problem: "live" CDs are ripped perfectly with my drives (no silence like the originals) and burned exactly with Feurio.



Feurio reads to a single WAV and you don't have to split tracks afterwards. (Open the "Copy" dialog completely by pressing "More Details" and select "Read tracks linked" -disable "kill digital silence"-)

I think that EAC also does this, but for me Feurio is easier and faster...

Thank you minix for reply:
I try to be more clear:
I must rip into single wav, then split into several tracks (maybe using CUE sheet), then encode to mp3s; I don't need to burn again

If you encode to MP3 is when you lose the linked tracks.
Converting to MP3 introduces silence if the end of the track doesn't coincide with the end of frame (which is almost always).

You can split the big WAV perfectly in several WAVs in the sector boundaries (588 samples) in order to be burned OK... but if you encode to MP3 you'll have silences between tracks. (Maybe there are options in the encoder to avoid this).
You better encode to a big MP3 and I think there is some Winamp plug in to have tracks and titles from a cue-sheet. Do it with EAC.

Firstly, if your ripper is capable of ripping WAVs without gaps (either directly or by splitting from a cuesheet) then a format that is instrinsically gapless - MPC or OggVorbis - will also have no gaps (though WinAmp and certain other players need special plugins to support gapless playback if you use WaveOut or Microsoft Sound Mapper because they close and reopen the output channel to your soundcard, adding an extra delay between tracks! I'm told DirectSound works OK)

If you must use MP3 for some reason (like hardware player compatibility, though Ogg will soon have more hardware player support ) you have two options:

1. rip as a single MP3 of the whole album and use CUE sheets (this isn't well integrated in most players, though, especially if you like to shuffle-play your whole collection but try foobar2000's cue support )

2. rip as separate MP3 files for each track and overcome the gap problem in MP3 files in one of two ways:

2a. Encode using the --nogap option in LAME, e.g.
lame --nogap --alt-preset standard
This is supposed to add extra information to allow the decoder (or lame's own decoder at the very least) to correctly shorten the last frame which should only be a partial frame to the same length as in the original WAV. I don't think it has any adverse effects, but it's not well documented AFAIK - do you need the whole album in the same commandline or will --nogap work on individual files, ripped and encoded one at a time?

2b. Play back the files using the MP3splice plugin for Winamp 2.x (see end of my sig for a link). MP3splice works amazingly well with all kinds of mp3 files made by different encoders and will preserve gaps that are supposed to be there, so I use it nearly all the time I use WinAmp (unless I need to us a SSRC or diskwriter output plugin instead). It also works perfectly when you play MPC, Ogg, WMA, Monkey's or anything else you throw at it! If only there were an MP3splice gapkiller plugin for Foobar2000 my dreams would be fulfilled, and a hardware player with mp3splice too would be fantastic!

There should be no harm done if you use both solution 2a and 2b at the same time, either.

Ok... how? Maybe using EAC?

AFAIK, EAC editor doesn't do it.
But you don't have to do it if you extract to a WAV per track instead of one big WAV.
Those WAVs shouldn't have any silence if the original CD doesn't have it. (all tracks in original and WAVs will be multiple of 588 samples).

CDWave will cut in sector boundaries.

I'm thinking better...
I think that if you split the big MP3 with "lossless editors" like MPEG Audio Scissors, MP3DirectCut, MP3Trim... the MP3 tracks may sound without gaps...
At least they cut in the frame boundaries...

I remember having this problem of gaps too. Was created by the mp3-format, all others don't have such problems. (Though I only tested this with vorbis, mpc and wav)
If you want to stick with mp3, I remember that with Lame you can have a switch to prevent this gaps. Something like -nogap, don't know exactly. Look into the documentation for that. The player has to support this though, I think Winamp would do this.
Easiest way is not using mp3 anymore......

Someone says these are two separate questions. True, but it seems goal is to make a perfect CD copy... There are a lot of ways to do so (and a lot to fail too...).
Here are a few good ones

* Easiest, safest way: copy image & create cue sheet (EAC, secure mode). You'll get one huge WAV file (the entire album) + a cue sheet. Then burn with EAC, using the cue sheet.
* copy selected tracks (without gap detection) (EAC again, secure mode again). Then burn them with a program of your choice, but note that programs like Nero insert extra gaps without telling you (can be disabled, but you gotta know it...)

Note: copy with leftout gaps (= EAC command, after doing a gap detection), and let Nero insert gaps is indeed possible (what the thread starter seems to be after). But it will not give you an EXACT copy (modified gaps!). But it is still better than a standard EAC rip (gaps included), with new (extra) gaps appended by Nero, that most people get without even knowing

Hopes this helps



great!

Thank you all for reply.
Yesterday I've done some tests.
Using EAC I can extract tracks without any gaps at the end or the starting of each tracks.
I've done some test ripping each track in a wav file, or ripping the whole cd into a wav and cue sheet file: then EAC can split the big wav using CUE sheet information: tools\Split WAV by CUE Sheet.
Both the tests were ok, the wav files were without gap and checked them with Sound Forge.

Now the only problem seems to be the gaps introduced by the mp3 encoder.
I use Lame 3.92 and never heard about --nogap option.
There is someone that use this without any problems? Can you tell me if hardware players can support this?
However I'll do some tests with my Kenwood Car player

Aren't the frame boundary gaps on the order of 1/100 second? That (or a similar length truncation
to avoid the gap) is a lot less noticeable than the 2 second track gaps originally asked about.

588 samples.
1/75 seconds.

That's a maximum pause (or cut in Nero) of 13,3 thousands of a second, if the length of the WAV is not a multiple of that.

This was mentioned before in this thread

It is not really documented as it was never finished. It had problems too, when I tried it. The VBR headers were missing on all but the last file (fix with VBRfix )

A working -nogap option was something good that Blade had, but as we know the sound quality sucked.
