I have a CD ripping application based on StarBurn that has been out in the field for several years now with *millions* of discs ripped. First, I'd like to say that overall StarBurn has performed very well, thank you!

Unfortunately it seems that there is a problem with GetTOCInformation() and gapless audio discs. I'm not sure if this is true for *all* gapless audio discs, as I don't have that many to test with. The problem is very simple, it seems that even though your "slow ToC read" claims to scan the pre and post gaps of the tracks, it doesn't seem to work and is incorrectly reporting gaps between the tracks of these gapless audio discs. I have several examples, but I have included data from one of them here to illustrate the problem... So, is this a bug in StarBurn, or am I missing something?

(use fixed font for clarity)

13 94992 99695
14 99754 105757
15 105870 107325

As you can see, the parsed ToC entries show the standard 2 second gap between tracks. However, upon examining the PQ subchannels of the disc it is immediately obvious that these gaps do not exist.

Is there any way to have ripped and zipped this particular CD image with Alcohol? Put it somewhere on the ftp (we can provide you with an account if you don't have any spare) so we could burn and run StarBurn against it. Thanks!

Have you tried using:

StarBurn_SetFastReadTOC(TRUE);

If not then try it. This will probably fix your problem.

For example, if you rip a disc using the slow mode and then burn the wav files produced and then compare the new disc tracks with the original in Nero(disc information in Nero) your track lengths will most likely not match. I've seen anywhere from spot on to several seconds difference. If however you use fast TOC reading you will get a one for one copy of each track(eg track length will match). Fast mode seems to simple read the TOC information and assumes it is correct without trying to guess at it.

Exactly! However accurate TOC read should work as well...

Okay, I'm working on setting up an image that you can download right now. I'll let you know when it's ready. In the mean time...

Correct me if I'm wrong, but when FastReadTOC is set to TRUE, won't you just report the length of each track as being the start of the next track minus the start of the current track? Therefore, the vast majority of tracks will be incorrectly reported as being 2 seconds longer then they actually are, and all my rips will have 2 seconds of silence at the end of them?

You're correct. It works like you said.

Any preliminary thoughts on this yet? At this point I don't have any time left for waiting so I will code my own ToC generating function based on the subchannel data, but it would be nice to know if my code will be permanent or just a stand in until StarBurn is fixed...

We'll take a look and fix the code of course. The problem is we're quite busy with the V10 SDK release and really have no time right now :(

P.S. Or will not release anything ever :)
