Hi Alcohol Soft

Here is the System Info report you requested to be added in support posts. My post follows afterwards.




I don’t know if this is the right place to post this, as it’s more of a bug report, but I thought I'd bring your attention to a problem that has been in Alcohol 120% since 2005 involving the .BIN/.CUE image format. Basically, when dumping a CD that contains data on the first track and audio on the following tracks (an old computer game is a good example), Alcohol will throw the audio tracks exactly 2-seconds out-of-sync. This causes the first 2-seconds of a track to be played at the end of the track preceding it. By this, I mean that a song will start 2-seconds in, play through, get to the end (where a short silence is usually heard) and then instead of going to the next track like it normally should, the first 2 seconds of the next track play as if they are part of the song. Then the next track will start seamlessly, except 2 seconds in, and this process continues throughout the whole CD.

To correct this, you have to edit the .CUE file created by Alcohol with Notepad and shave off 2 seconds from the middle set of digits of every track numbered #3 and onwards (track 1 is data, track 2 is audio but is always in sync). By doing this, the audio is set back into its original position and play's perfectly. The only reason I know how to do this is because I stumbled upon a person who had commented on this on a website, otherwise I would have had no idea why the tracks were all mixed up. Very few people seem to be aware of this problem, and even fewer would know how to fix it.

I know that BIN/CUE is a foreign format to Alcohol, as is CCD, but the benefit of BIN/CUE is its portability and support. Almost every single burning program supports BIN/CUE, while only a few support MDF/MDS or CCD. In its current state, the BIN/CUE support in Alcohol is useless for audio CD's if the person making the image is unaware of the de-synching problem, and even if they were, they’d still have to know how to edit the .CUE file. Given that Alcohol 120%’s is regarded as the best disc-imaging program out there, I don’t think it’s much to ask for it to properly support the most basic of image formats.

I’ve chosen 3 games to use as part of my experiment to show you the problem, each one ripped to BIN/CUE once with Alcohol and then again with CDRWin I’m using CDRWin as a comparison because I had heard that data+audio CD’s ripped with it have their audio in normal sync and, lo-and-behold, as the following experiment shows, they do!. Up until a few weeks ago I thought it was a problem with the BIN/CUE format itself. Anywho, let’s begin:

Monkey Island 1 (1992) - Plain data track and lots of audio tracks.
Quake (1996) - CD-XA data track and a number of audio tracks.
Starsiege (1999) - Predominantly plain data (500mb) with 4 audio tracks.

Here are snippets of the .CUE files for each game, one for Alcohol and one for CDRWin. Note the discrepancies in bold and similarities in underlined italics:

Whew!. As you can see, the games ripped with Alcohol have their audio tracks 2-seconds forward out of place, while the CDRWin ripped games are perfectly normal. The only way to correct the Alcohol created Cuesheet files is by editing them and removing 2 seconds from the middle set of digits of each audio track, thus restoring the tracks original position so that it is identical to the CDRWin Cuesheet. It seems that maybe Alcohol isn’t compensating for the pre-gap or something, I have no idea.

Would you be able to fix this problem?. I don't really know what else to say, but I've tried to provide as much information about the issue as possible, so I hope you can help.

This is a known problem of Alcohol regarding the cue/bin format, it just doesn't use the postgap/pregap information. I believe that the development team will look into it.

I reported this a long time ago (can't even locate my thread anymore on this forum) with some sega saturn games as an example.
Seems like a mayor issue, and still not fixed....

Check out my join date, that is when a reported the problem!

These were my original findings on Tue Jul 26, 2005 (I posted the following on another forum):
QUOTE
Notes:
DO NOT use alcohol 120% to do a bin/cue rip.
Alcohol uses RAW read mode, without subcode analysis, so you will loose gap data.

Also alcohol has a strange way of making/parsing cue files.
A mixed mode disc has a PREGAP between track 1 (the data track) and track 2 (audio track). This PREGAP seems to move every audio track following it, up by 2 seconds.
CDRWIN takes this into account, and will shift every track in the CUE down by 2 seconds (so when burning they will get shifted back up by 2 seconds due to the 2 second PREGAP).
Alcohol doesn’t do this. So all your tracks are actually shifted up by 2 seconds after burning. So they are no longer on their original place.
More info: http://forum.alcohol...amp;#entry99671

I don't have the details anymore, and the link to my bugreport (and technical details) have since been removed.
I don't care anymore, since I've moved on to Linux +1y ago, but it might help others with bin/cue images.

Pandor, this is the trial user forum. Since you are a member you should get access to the members only section. As for your post, we have redone the forum since you were last here. Much of the forum has been cleaned up and so I am sure your post was cleared because of inactivity. If you still need any help with Alcohol please use the Customer Only forum. You can gain access by asking the Admins for access....

As i said, i really don't care about the bug as i'm no longer a win32 user.
I was just surprised that this bug is still not solved, after 2 years...
That reminds me why i switched over to open-source software tongue.gif

If you aren't a Win32 user anymore then why the need to visit the forum for a Win32 program....

Sorry for bumping this, but I was wondering if anyone came up with a solution to this as I am experiencing it too. Alcohol is great and I'd definitely purchase it if such a glaring problem were resolved!

The issue is still being looked into, however if you use Alcohol's native MDS format, then this problem does not occur.

Hello,

i know this thread is very old, but this bug is still not fixed.

Creating images in BIN/CUE format will made audiotracks 2 seconds out of sync.

I found some images on a archive website, that are also having this issue.

So this is a major issue.

Please can the support team fix this finally?

 

Thanks.

This has to do with the reading of the subchannel data. The problem is that some audio copy protections use these subchannel data and it seems that it is a bit difficult for Alcohol to tell when the subchannel data are used for the postgap/pregap purpose or they are used for copy protection. In order to read the subchannel data you must use the Audio CD+ datatype but then you can't create a CUE/BIN image. I don't know if there can be a solution for this problem, only the Development Team can try to find one. However I don't think that this issue is so important.

When i use MDF/MDS or CloneCD format then it's not happen, also if dump the disc withtout subchannel data.

BIN/CUE images with audiotracks are broken and for archiving discs it's important to have a proper dump.

Can you inform the issue to the development team?

Thanks.

The issue is known, I don't know if the Development Team will find a solution.
