    Minimum track length for Accuraterip

    I'd like to try this again, this time in this forum.

    To start, I'm not using Accuraterip v2... just the one that's always come with EAC 0.99 pb5. Now, here's what I'm wondering about: On some very short tracks I get "0/0 No matches" even when all the other tracks give me something like "Accurately ripped 03/03". I want to know how short the song has to be before Accuraterip just decides not to accept it.

    The last time I asked this, back at Hydrogenaudio in January, I got a few guesses: if it's 50 frames, if it's 450 frames, if the track is silent, and if it's a bad rip. None of these apply to me. I've ripped a CD that gives me all results as "Accurately ripped 03/03" except for the last 4 tracks, which give me "0/0 No matches". These tracks are 30, 14, 5, and 7 seconds long. So, three of them are greater than either of the frame amounts guessed (6 seconds), none of them are silent, and there's just no way all 3 people who ripped this CD got got the same thing on every track except the those tracks by some magical coincidence, where we all happened to get completely different results. I do test and copy, and both CRCs match up for the tracks every time and the CD is spotless. Sure, I considered that sometimes 2 people will get different results and so it will sure up as "0/0 No matches", but there's a third person. That this third person did not get any of the same CRCs on any of those tracks as either of the other two people... no. And, there is only one pressing of this CD ever.

    Now... does anyone know the cutoff point for when a track does not show up in the database? It disturbs me quite a bit. For your use, if it helps you: 0040d0aa-0513949b-8b0df41c. It's the Disc ID for the Accuraterip results.

    Off the top of my head it is 450 frames.

      If it's 450 frames, then something else has to be happening. I've checked over 30 CDs now, and I have yet to see a single track that's 8 seconds or less show up in the Accuraterip database. 450 frames is only 6 seconds. And I'm not even saying 8 seconds is a firm cutoff point for my experiences - just the most common length I've seen that hasn't yet shown up. Sure I've had some over 10 seconds, but it becomes hard to know if there really aren't conflicting results at that point.

      I just find it too coincidental that allllllllll the tracks that are 8 seconds or less in my library happen to be the tracks on which people got conflicting results. There just has to be something more to this.

        I ripped "Queen - Made in Heaven" recently on my RipNAS. Track 12 titled "Yeah" is 4 seconds long, and it ripped accurately though I did note that the confidence figure is a lot lower than the other tracks. It had a Confidence of 84 whereas all the other tracks on the CD are between 195 and 200. I ripped the disc again it seemed so odd, but I got the same result and then I reaslied that it was the very short track that had a low Confidence figure. I assumed that being such a short track a lot of people had trouble ripping it so a lot less people had got the correct result (or at least the same result as I did).

          Why would a shorter track be harder to rip?
