Hello,

I've read somewhere that Audiochecker is fair enough but not 100% reliable. I've just checked some of my flac files and Audiochecker tells me sometimes that a file is 95% MPEG (while the rest of the album is 100% CDDA).

How can it be that sure (95%) while it is completely wrong since I ripped it myself from a CD? (or maybe my brand new CD was created from MPEG files  )

Thank you in advance.

...And if Audiochecker is reliable then all the flac files I bought online are transcoded from MPEG files...



(You'll say that if I didn't realise that listening to them, then it doesn't matter. Still, it's a CON!)

Have you tried asking the developer for your money back?

?

When I say a con, I mean from the online store, not from Audiochecker developer!

Ok, though my reply ought to convey that, personally, I don't have much faith in the accuracy of that program.  If it doesn't, then hopefully this reply does.

It is true that there are CDs that can be purchased from legitimate places that are sourced from lossy, however.

I recommend searching the forum as this topic comes up quite a bit.

It's just a known limitation of the software. Audiochecker is relying on the Aucdtect software (separately maintained, and not updated in a long time) to do the analysis and generate those percentages, which are an estimation of how likely it is not a lossy transcode.

As you can see in the first graph at the Aucdtect testing results page there's about a 7% margin of error.

It's well-known that tracks without a lot of high-frequency content can produce a 'bad' result.

Thank you both!

That's what I did but I made the mistake to search for "Audiochecker" in the CD Hardware/Software setcion (which gave me one closed thread)!

Sorry for the thread revival, but just wanted to note for future google searches that I did a test with Audiochecker 2.0 beta.  I converted some songs that I downloaded from iTunes (256kbps AAC) to FLAC.  I then used Audiochecker to analyze the files and it showed that all but one were CDDA with 100% probability.  This is proof enough to me that Audiochecker is not completely reliable if you weren't already skeptical.

Agree, I did few test myself in the past (http://www.hydrogenaudio.org/forums/index....st&p=808771) and I had the same results. The software is not 100% reliable.
