Hi,

got a mix mp3 album and am trying to burn it so that they are no gaps between tracks. I am using Nero and Easy cd creator.

Everytime i try and burn it, i get small gaps in between the tracks..not the 2 sec ones but small 0.5 sec gaps that are there by the way the beat goes off time when a new track starts to play. I know my cd recorder can burn perfect dance mix cd's but that was done by one to one copying of the audio album (not mp3) to cdr.

Can ne1 help me? its really frustratig because as i dj my hearing is intune to the beat of any music and when the beat shifts (i.e. from end of track 1 say to track 2) i can really hear it. boo hoo!

I answered this yesterday when you posted the same question in the CD-RW forum: http://www.cdrom-guide.com/forums/showthread.php?s=&threadid=9989 :nono:

hi,

thought i had deleted that post for some reason. Think it was a different forum..doh!

Well i thanked you for your help in the last post on cdrw.

Sorry bout the double posting.

cheers

mr g =)

No problems, accidents happen. ;) I hope the suggestion solves your problem. You may want to look into burning with Feurio, the fully functional demo is available from www.feurio.com

It contains a Track Editor that will let you audition the beginning or end of MP3s before burning, which will be usefull in your case.

was wondering if there were any other progs like mp3trim? i like it but can't afford to pay for the full prog..is there a shareware prog or freeware prog that does what mp3trim?

cheers

mr g

There are some other trimmers/cutters here: http://www.hitsquad.com/smm/news/998/ (however, unlike MP3Trim they resample the MP3).

cheers

mr g

for editing out silenses from start/end of files or for joining several files together to make a one track cd etc i use cooledit pro.

info on how to do this etc can be got from Here (http://colinsfaq.netfirms.com/main.html)

colin. :clown:

cheers m8.

will try that.

mr g

How can you afford Cool Edit Pro if you can't afford MP3Trim? :confused:

good point Keymaster. Just downloaded it and tried but as you quite rightly said can't afford it.

I thought there was a shareware version that i could use without any limitations but i guess cool edit developers didn't want ppl to fully use it and disabled save! bah! :mad:

Its so annoying though cus mp3trim is perfect except i have a few files that are over 7 mins long and they are part of the mix! Doh!

Haven't found a prog as good as mp3trim.

2 second gap in Nero


Against the often expressed opinion many (but not all) CD recorders are able to burn audio tracks without the 2 seconds gap between the tracks. It's also untrue, that „disc at once" burning means, that a gap of zero seconds is written. The „disc at once" burn method just gives you the freedom to choose a gap length of your choice. Generally it's best to burn audio CDs using the „disc at once" method.
To modify the gap between audio tracks just double click a track in a Nero audio compilation. A dialog will pop up, which allows you to enter a pause length of your choice. If you would like to change gaps of several tracks, then select these tracks and choose the menu command Edit->Properties and enter the desired gap length. Note please, that the gap before the first track must be between 2 and 3 seconds with respect to the rainbow book definitions. It wouldn't make much sense to change this gap anyway, because nobody would be able to hear the difference.

Once you entered the gaps of your choice click on burn and leave the „disc at once" option checked (if your recorder supports DAO). If your recorder doesn't support DAO or variable gaps in TAO, then you will see a warning, telling you, that some of your gap settings couldn't be applied. In this case your recorder is unable to write the CD, that you want. The only thing you can do in this case is to carefully select your next CD recorder and make sure, that it's capable of DAO writing.

Hope this helps

In easy cd creator ensure you have disc at once dao option ticked and if your recorder supports it the 2 second gap will be eliminated automatically cdrwin gives same result

Sorry about the double posting I thought it hadn`t gone added smilies and clicked again

sidneyK, mrgreedy has already said he eliminated the 2 second gap when he started the topic. As for the double post, you can delete it and the apology for it by simply clicking the Edit button and checking the delete box. ;)

cheers neway Sidney.

I've kinda figured it is the actual mp3 album i.e. gaps inherent due to encoding to mp3.

What i've found out that a milisecond (or less) gap is produced sometimes at beginning of mp3 files. This gap is hazardous when trying to burn a dance mix cd where beats are in time going from one track to another, thus, when there is a gap between tracks you can hear it quite clearly.

As for Nero, I updated firmware and ASPI drivers which helped a lot. Just needing to eliminate the gaps manually at the mo.

mr g :blockhd:

As this topic is raised on a daily basis, why has no-one mentioned the 'fix' in Nero (sorry keymaster if it was in your original post reply).

Select tracks 2 to the end, click on properties and select merge with previous track. Set it to 4 frames and this should sort any clicks, blips, gaps etc etc etc in continuous play albums.

As people have said, unless you physically edit each track, join them together, tag the track start points etc, you can never totally eliminate the gaps. However, in my experience, the fix above works 99 % of the time.

Crossfading won't eliminate the gaps of silence that MP3 encoders add to the beginning and ending of each MP3. It will eliminate any glitches that occur as a result of eliminating the gap (probably caused by either the burner and/or the fact that all tracks must start at the beginning of a sector).

The best way to eliminate the silence which actually exists on the MP3 is to either edit the MP3 or convert to wave and edit the wave. If you rip to wave you will not get this silence, but as soon as you convert to MP3 you will get this silence added to the beginning and end of the MP3. MP3Trim is the best software I know to get rid of this silence (it was originally designed for theis). It will trim the MP3 without resampling it, and can normalize it willdoing this.

Whilst I agree with the technicalities of what you're saying Keymaster, I am saying that crossfading does eliminate the gaps / silences as far as the listener is concerned.

4 frames is equal to the length of silence added when audio tracks are 'ripped' to MP3. By crossfading, you are purely overlapping the silence at the end of one track and the start of the next track with the music. To the human ear it is seamless (usually !!!)

green_blade, you do raise an interesting issue. However, crossfading for 4 frames will only get rid of a click not the silence introduced by MP3 encoding at the beginning and end of each track. In fact I recall complaints posted in this forum that even with the crossfade the short silence remained.

There are 7350 frames per second in a stereo track. Even if with 4 frames crossfaded (presumably on each track) that only eliminates less than a millisecond of the audio track. This is not enough to be audibly noticable, which is probably why it's not noticed. :) If the gap is 500 milliseconds or 1/2 second as mrgreedy described, and long enough to throw the beat off crossfading 4 frames would not be any help. Possibly crossfading hundreds or thousands of frames would help. :)

I have seen information on how much silence is automatically added to the beginning and end of some tracks. I will post it if I can find it again. However, some ripped tracks may contain even more silence resulting from the ripping process. For more info problems with gaps on MP3s see Xorys' MP3 FAQ (http://webhome.idirect.com/~nuzhathl/mp3-faq.html#ques117).

Acoustica MP3 (http://www.acoustica.com/download.htm) will convert MP3s to waves and remove this silence at the beginning and end of the converted wave files automatically.

thanks for the plethora of information guys. Really appreciate it. This thing has been bugging me for a while now.

I will try the mp3 conversion prog you posted keymaster and hope that it trims enough silence. If not will then edit it. One thing i have to ask though, the wav editor i use takes ages to load up (well not ages but long enough to be tiresome when doing 10 - 15 tracks), is there a prog anyone knows of that has a faster, more efficient approach to wav editing?

cheers

mr g

Nero has a built in Wave editor. Feurio also has a wave editor and the track editor lets you audiition the first and last few seconds of a track (mp3 or wave before burning) since this is where many files have problems. Download Feurio from www.feurio.com

Keymaster, or should I call you 'Framemaster' !!

I receive loads of albums on MP3 and burn many 'continuous' mix albums for my friends. All I do is use the 4 frame 'crossfade' option in Nero and as I say, 99% of the time, it totally eliminates the gaps giving a seamless mix.

Again, I don't doubt what you are saying but it does work.

right...will try both of these methods tonight and tell you the results. Thank you both for your help and fingers crossed these mix albums i've got will be continuous.

Will post what happens.

mr g

green_blade I agree with what you are saying. In most cases a crossfade is not even necessary, in some cases the crossfade works. But there has been more than one post here that even crossfading didn't work and only editing the MP3 solved the problem. If the silence gap is anywhere near a 1/2 second, I think the edit may be required.

This may be useless info but i use easy creator 4 , what i found that seems to work is i put all the tracks in the ' ready to burn window' , then click the edit button on the top toolbar , click select all, this will highlight all the tracks in the bottom window , right click on the highlighted tracks and u have the option merge tracks .

Merging tracks is not the goal here. This will not allow you to skip to a particular track any longer since all the tracks will now be one track. Furthermore if the track has 1//2 second of silence unless there is an option to remove the silence there will still be a gap of silence in the mergerd tracks (you just won't be able to skip to it).

See what u mean:tup:
