Accuraterip ... AR but maybe damaged, A question for Spoon/Gregory/Greynol Options

[sauvage78]

Hi, I just searched for doublons/clones in my flac collection with cuetools & CloneSpy (a clone finder software) & I happened to find something strange: a clone with an overall different checksum (so technically CloneSpy doesn't detect it as a clone) [Edit: My collection is only made CDImage.flac] but with all matching checksums against the accuraterip database & with a very high confidence for all tracks. So the data is obviously the same ... but there is a problem: the CRC for track 1 with or without silence at the end of the log doesn't match, hence the overall checksum difference & the non detection as an exact clone by CloneSpy. So my question is: am I right to interpret this situation as a non-detected scratch (or truncated audio) in one of the 2 rips ? I mean a scratch (or truncated audio) located in the 5 first frames of the rip which accuraterip might ignore ? (I know AR ignore the last 2940 samples but does it also ignore the first 2940 samples which might be the problematic part in my case). Is my interpretation of the problem right ? or is there another explanation ?

Here is a copy/paste zoom in the problematic part of the logs:
Log1: All tracks accurate

--    [BB8A18D4]    [C665239A]

Log2: All tracks accurate same checksums for individual tracks in the beginning except at the end:

Note:
The album is Pantera - 1992 - Vulgar Display Of Power original pressing
& I know that:

CODE

Track    [ CRC32  ]    [W/O NULL]    
--    [BB8A18D4]    [C665239A]    
01    [52E2E723]    [303E0CCB]

is the good checksum if one of the 2 is bad. (I compared my own rip with several 3rd party rips as I own the CD ... it's one of the best heavy metal album of all time)

So the question is not which one is the good rip but rather what is happening technically & why a rip which, at first look, is perfectly accurate rip is in fact maybe damaged.

I am worried because it was one of the very first doublon I found ... so it might not be such an exception ... I am scarred to search further now ...

Edit: By the way, we need an april update of the database Spoon

Again, thks for trying to help.

Sorry for the delay, but I was struggling with various softwares in order to try to achieve the same result as yours which actually I didn't succeed (yet). I have installed Audition 3.0 but I didn't have any luck with it. I founded it increadibly huge & bloated compared to my rememberance of Cool Audio Edit. So I get back to Cool Audio Edit Pro V2.1 which is much more suited for my needs (I like fast & small, efficient software ... & if possible free) ... basically the interface is the same than Audition but I don't know why I finally found a non-flat curve with Cool Audio Edit Pro after much zooming. I think my problem might come from the fact that I don't zoom enougth due to the unusual shortness of the files. I don't like using non-supported software, so even if great & even I had a begining of success, I don't see myself using Cool Audio Edit nowaday, it would be like going back 10 years ago (& I hate Adobe & what it has done to it to be honest ) ... so I tried the lastest Wavelav too ... which lasted 5 min on my drive as I don't like the interface ... I was wondering if I should try Sound Forge but I gave up the idea when I saw that it has some support for video ... which is definitely not something I want in an audio editor ...

I finally get bored of all these huge & slow audio editors, specially as trying all these expensive softwares forced me to install Antivir which slow down my poor Sempron 3000+ (Barton) even more ... so in the end, I have uninstalled & deleted everything !!!

I'll try again with Audacity later, right now I am playing with Wavosaur to see if I can split without automatic dithering which is also an Audacity non-starter for me.

Your advice doesn't seem that hard with the right tool, unfortunately I don't want to use Cool Edit. I don't now why I was so unsuccessfull. I must have done something wrong to begin with or I have became completely dumb. Anyway I'll try again later as actually I am bored
