This is NOT lossless. This has been transcoded into flac from some lossy format, most probably from mp3 320 cbr. Here is the spectrum of first track, if anyone has the lowest understanding of how spectrum and frequency cut-offs work in flacs and mp3s, will get it. I regret downloading this 1.1GB just to find this out. I am giving one screenshot, but all tracks are like this. https://i.imgur.com/D0gQXKb.png

I don't undrestand how it can be, because file size's on mora and these one - similar. And I was listening to lossy versions of this songs, they are completely different in sound, it's not a placebo feeling.

It doesn't depend on the size, if you transcode mp3 into flac, the file size will increase and it will become a flac format file, but it wouldn't become "lossless". The only way to confirm this is to do a spectral analysis. For true lossless flacs, the frequencies are supposed to cross 22k hertz, and they never get any "cut-off", see the image, how smoothly they got cut off above. MP3 (320kbps) formats get a frequency cut off at 20.5 hertz while they get encoded, so later when you trancode that mp3 into flac format, the frequency still stays same, only the compression decreases. Did you directly rip this from mora? If so, then mora is doing some annoying work there, feeding people with re-transcoded stuffs. What lossy version you listened to ago? What kbps?

Not directly, it's pointless work to do transcode, I think. This rip was done by umbrellafactor, I'm now listening to a lot of their rips, if it Hi-Res, it sound so. If it really how that you said - it's sad, because there are two ways:1) bad original source(it's their first album) or umfactor really did something with songs... And I was listening to oddloop album in AAC 273 kbps.

I searched in some other private tracker and found a 16bit flac version of this album, this one is true lossless, see the frequency for that same song. https://i.imgur.com/wypOLtR.jpg Actually, the difference in audible quality doesn't always hit you immediately. 320kbps mp3 get a frequency cut of at 20.5 khz, but human can hear only upto 20 khz, not to say practically a person hardly goes over 18 khz, so trying to find immediate hearing difference is somewhat pointless. The difference might hit hard when you have been listening to lossless audio through some good dac-amp and some costly headphones for a long time.

I checked all tracks in spec prog, there are all stucks on 20,5, yep. But I also check the file from another one release of this album from here ( it's no seed, no one can't download it, stucks on 25%) and I found the same spectrum on song from their, very intresting thing. https://imgur.com/a/dvSVkqw
