    I’ve got a problem with the audio cd’s that I burn, and I don’t know if it's a function of:
    - cdrw drive or its installation
    - the drivers associated with that drive
    - the burning program I use
    or other possible causes. Anyway, the problem is this: after the final track, a short burst of sound – much shorter than one second (I don’t remember the typical length) can be heard. It sounds as if this is repeating some *short* clip from earlier in the final song. This clip is after the official end of the track, and as such doesn’t get played when I play the cd on my computer. However, when I listen to the disc on my discman (with the anti-skip feature off), I can hear this burst of sound right after the end of the final track. I can also observe this feature using my computer if I set Cdex to rip the final track using an offset of, say, 25 frames (i.e., 1/3 of a second). Then the “burst” of sound is easily visible. EAC can’t show this because you can’t set it up to read with that amount of offset. I hear it on all the cd’s that I’ve burned in the past using my drive (at least all the ones that I’ve listened to to check out the problem). I have cheap cdrw drive, but I’ve listened to cd’s that other people have burned for me, and I’ve heard the same thing on some of them as well. It could be the program (I use NTI CD-Maker 2000 Plus) but some of the cd’s that other people burned for me, that also have this problem, were burned using EZ CD Creator. I run Windows 2000 Professional, and have tried reinstalling it and messing with the drivers and such, to no avail. I still get that annoying little burst at the end of a disc. I anyone can shed light on this, I’d much appreciate it. Thanks.

    Try Feurio! and report if the problem still exists.

    Is it free? I've tried to get EAC's burning program to work, and have had only a lot of bad discs to show for it. But maybe since I upgrated to Win2k and now have EAC 0.9 b4, which is supposed to have fixed some of the burning issues... I'll try that again. Also going to try to test out a couple of things on my computer.

    The discman shouldn't play it. Does it show up in other CD players ?
    I don't know where it comes from, but as long as you need a huge offset in order to reach it, it shouldn't cause any problem.

    Can you recognize that it is a repeated part of a previous track, or is it just some burst of noise ?

    Yes, the burst of sound _is_ part of the final track, seems like something that was going on maybe 10-15 seconds earlier, though the same "burst" effect is going on even on cd's where the final track is only 5 seconds long (though in this case, it may be pulling still from 10-15 seconds earlier, just from the second-to-last track. I've been meaning to test this by burning something with 20 seconds of silence as the final track (in which case the added "burst" should itself be silence), but I havne't done that yet. Still, I'm reasonably certain that the burst is sound from 10-15 seconds before the official end of the disc.

    So anyway, there's this burst in the lead-out. I can set EAC to read-ahead (positive offset) 20 frames (the maximum you can set it for) and it just shows silence... perhaps it doesn't really read the data on the audio cd, but just sticks with the cd's official ending and adds 20 frames of silence to simulate having read 20 frames into the lead-out. If I use CDex and set it to read 20 frames ahead, it does get the burst of sound after the official end of the disc.

    It may be that this burst actually isn't on the disc, but CDex (and the discman when it isn't set to anti-skip and thus isn't as carefully calibrated) get messed up in the lead-out and bounce back 10-15 seconds in reading the disc, hence the apparent burst of sound. But this only happens on burned CD-R, not on original discs, so if this is true then there's a problem with my burner or burning program closing the disc or writing the lead-out correctly. Or it may be that the burst is added in the lead-out.

    Either way, there's some sort of problem, and I'd appreciate any input from people who have a better understanding of CD-R media, and of the burning process, than I do. Thanks.

    BTW, I've tried Feurio, but can't get it to work - none of its drivers recognize my burner.
