Hola...i have made some audiotext files, but i dont know wich programs can i use to burn the mp3 files to a mp3 CD. I want the audiobook to play back continuously in my CD-DVD player, without gaps.....in mp3 format...i tried to use foobar200 with nero, and had no success....are there other solutions?? maybe free software??..

i also tried cdexppro, but had no success......
maybe there is a complete tutorial for making this type of CDs...i am using winLame....with gapless mp3 as the output.

Thank you..

Itunes (I'm running version 8) has a gap length choice which can be set to none. I haven't tried it on spoken audio though...

ETA: Ah never mind... the option goes away when you select mp3 cd.

Do you mean you want to leave the files in mp3 format, or are you recording audio CD's from mp3?

Nero will let you remove the gaps between tracks for an audio CD. If the CD is a data cd with mp3's, there is no defined gap on the cd, it is simply the time the player takes to change to the next file.

Guillermoa, we need more details on exactly what you're attempting.

In addition to Boomcoach's pertinent question to clarify what type of
disk you're making, what is the source material you're starting with?
Is it MP3 files, such as those from LibriVox? If so, have you split
those files into smaller pieces? See the LibriVox how-to guide on
splitting with MP3Splt. Using the recommended options, it will place
the split points in existing silent gaps (i.e., pauses between words or
phrases), thereby avoiding having the splits occur in the middle of
words (splitting words does produce a hiccup on playback).





For those interested in a more technical discussion:

First, each track on standard audio CDs has a pregap section. On most
commercial music CDs, pregaps contain two seconds of silence, as a
sound buffer between songs. On albums of live recordings, the pregaps
usually have sound from the recording so that you get continuous
playback from start to finish, without any silent gaps.

All audio CD buring software I've used lets one select whether or not
to include a silent pregap, such as gypsygirl reports for iTunes. The
better burner programs allow one to individually set the length of the
pregap for each track.

Second, MP3 disks -- as distinct from standard audio CDs -- are
nothing more than CD-ROMs which contain only MP3 files. You can look
at what's on an MP3 disk -- see the content listed by filename -- with
what ever passes for the file manager program on your OS (e.g., My
Computer -- aka, Windows Explorer -- under MS Windows), just like you
can with any CD-ROM.

Therefore, because they are not audio CDs, there's no such thing as
turning on or off track pregaps, since they don't exist on CD-ROMs.

I've burned dozens of MP3 disks for use on several different CD players.
I quickly discovered that it worked better to avoid selecting "MP3 Disc"
in the burner program. Therefore, I always choose to make a plain CD-ROM
(which might be called something like "Data Disk" in the burner program)
when I'm creating an MP3 disk.


My research into your problem revealed the facts that most encoders
introduce silence at both the beginning and the end of an MP3 file.
And that decoders introduce additional silence at the beginning.
According to the LAME Technical FAQ, preventing these introduced gaps
is "very difficult but not impossible". Nevertheless, the latest
versions of LAME do have a "nogap" encoding option. But that doesn't
necessarily mean that the decoder in your player won't introduce a gap
due to the decoding process. "Even when the audio file itself does
not contain undesirable gaps, software/firmware/hardware design often
adds gaps during playback" (from HydrogenAudio).

Si...The starting point are three long WAVE files, each one of 2 Hours of time lenght. I made a big MP3 file of each one using Lame encoder (winLame)...wich has an option of making gapless MP3. Then, i cut each of the three long MP3 files into smaller Tracks of 1:45 minutes of time lenght, using mp3directcut. I ended with approximately 60 Mp3 audio Tracks for each one of the 2 hours MP3 long files.
Now...i want to burn a gaplessMP3 CD, wich means continuous playback, so that no silence imterruption would be heard when listening the CD......the 180 MP3 CD, in my CD-DVD stand alone player.
This MP3 CD can hold much more than 180 MP3 Tracks.

The starting point were three long WAVE audio files, made with an Olympus VN-4100PC digital voice recorder, of some live classroom lessons, wich i want to playback in my CD-DVD player in the form of a MP3 CD, AND NOT A WAVE AUDIO CD.

i will try the iTunes version 7, because the NEW version 8 has had problems when burning a MP3 CD...because it does NOT cut out the silences between the tracks, when being playback on a stand alone CD-DVD player.....so i have version 7 of iTunes...

Finally....i want to know other alternative software for making the MP3 CD burning with out the silence between the Tracks....

I will use the CDROM suggestion, and the iTunes software SOLUTIONS....and give you my results.....in this forum....



I want to know other software, free or commertial$$$, that can make this kind of gapless MP3 CD.....and, finally, i could not use the foobar2000 with Nero option....

Please, let me know of options that work, especially the ones that make the proces in an automated way, not a manual way.....because, for example, i could not be cutting each track manually to remove the silence on each track with an MP3 audio Editor.......wich will take me forever....since there is a very extensive quantity of WAVE audio files i will work on....including the digitizing of several complete class books...i am student in Philosophy at UABC-Tijuana, Mexico....

Theank you for the suggestions...

Guillermoa, thanks for the clarification. However, you have yet to say
exactly what the problem is you have when you listen to your MP3 disks.
Are there silent gaps between your split files? How long do the gaps last?
Is the problem something else?

As explained by both Boomcoach and me, if the problem you're experiencing
with playback is silent gaps between files, it is not due to the burner
program you're using (because there are no track pregaps on MP3 disks),
so switching burner software won't solve the problem. The problem lies
somewhere else.

Have you tried listening to your MP3 disks with more than one player?
Perhaps the CD/DVD player you mention is creating the gaps or whatever
the problem is that you hear. Trying listening with several different
players to see if you hear the same problem or not. That will indicate
whether the problem is with your player or the files on the disk.

Again, I've made dozens of MP3 disks with files split by MP3Splt and
have played them on several different CD players without problem.
It splits automatically, not manually. Give it a try; it's free.

The "gap" may also be hardware-dependent. For instance, I have a Sony Discman portable CD player that will play MP3 CDs. The bad part of it is, it runs the laser head back to the directory listing after each file has been played, even if the next on is right in line behind the one just finished, then back to the beginning of the next file. For a looooooong book, that can take 3-5 seconds each way. Frustrating, but there's no way around it.
