awesome ost, i fucking cried. Thank you very much.

I'm sorry, but it's not a flac. Or very badly encoded

What does it mean "not a flac"? This is the purest flac.
But if you mean, that it's not lossless, you are also wrong.
Why did you even decide, that the album is badly encoded?

The rate of the first music is below 320 kbp/s
And look at the spectrum of sounds with the Spek application you will be surprised by the result.

Are you serious?
The first and last tracks in their content simply do not provide a frequency range higher than 6 kHz per channel. These are quiet melancholy piano compositions, and how can their spectrograms jump to the highest frequency level?

What if we look at:
Track 02 (FLAC vs MP3 320 kbps -q 0 (HQ mode))
Track 03 (FLAC vs MP3 320 kbps -q 0 (HQ mode))
Track 04 (FLAC vs MP3 320 kbps -q 0 (HQ mode))
etc... What do you say now?

it's great, that you discovered quality checker for yourself, but it’s good to understand, what exactly you see on the spectrograms. If you’ve recently become interested in the lossless formats, then get used to the fact, that in lossless albums your checker will often find tracks similar to lossy.

@cakinou

A lot of old soundtracks released by Intrada have tracks under 320kbbs but it's true lossless.

Lossess means lossless that's all, I can rip a lossy source in lossless and it will be a lossless rip of the source.

Audio is a science, learn about please.

With spek I arrived at the same result on the first music despite the fact that the file is in flac or mp3 from where my remark

I will explain more - here is no audio material for high frequencies, so it simply can't have frequencies higher. Even if it will be raw studio material with 32 bit /192kHz, the spectrogram will remain exactly the same. To mislead buyers, the publisher could add white noise to the track - less at a mark below 16 kHz and more above 16 kHz. This noise you will not hear above 16 kHz. but you’ll be satisfied that it’s looks like a lossless quality. Example (made in "Photoshop"). I can do the same in "Adobe Audition", but for what?

For example, download "Luce" soundtrack and see, that there most of the tracks looks like this and "Audiochecker" says - Summary 9,53% CDDA. But listen to those tracks, there are almost only musical spheres. Yes, for such tracks HQ MP3 encoding is quite enough, but everyone can decide himself, to keep the original album in FLAC or convert to MP3. I just provide the best quality and never convert MP3 albums to FLAC. Sometimes I lower the sampling rate of Hi-Res albums, bringing their characteristics to real, because there are a lot of fakes among Hi-Res albums and their file size is impressive.

All, that I wrote about quality of 16 Bit/44.1 kHz version, applies to new 16 Bit/48 kHz version too.
