Problem with fake positives

[Huyyou]

Hello!
I'm having a problem with detecting fake fakes. A lot of FLAC files are detected as fake in the last few seconds, maybe because of fading effect. Is it possible to skip those last few second or something?
From 20k FLACs around 500 get fake detected.

Thanks :) !

Hey :-)

Only few seconds should not make a file to me reported as fake...
There must be a "bigger" issue!

Could you post a spectrum of one of those files?

As you can see, there is a kind of cutoff and some "lousy" noise above ~20500 Hz.

A 100% "real" flac would not show this kind of cutoff; see also http://forum.fakinthefunk.net/Why-is-one-fake-but-the-other-isn-t-td391.html

Nevertheless, it is "high quality".
You can go to the settings dialog (the gearbox icon) and activate the option "allow cutoffs above 20000 Hz" if you feel that these kind of songs are good enough for you

I have quite some users that insist that a real flac must not have a cutoff, therefore this option is available.
