Excellent stuff! Never heard these tracks in better quality.

Thanks for the unploading but these files are not real FLAC quality.. chack with Speq for vinyl rips and you will see there is a cut betweet 15 Khz and 20 Khz.
Waiting for the real (almost 320) quality files.

I don't know if I should correct you or agree with you XD

Whether or not there is a cut of at 15 (it's actually 17) or 20khz has nothing to do if it's "FLAC-quality" or not, but the source's quality or the recording hardware. I can see on my vinyl rips that between 2009 and 2012, all my vinyl rips have that soft cut-off at 17khz, but 9 out of 10 of my rips barely go above 20khz.

Also, the 17khz has nothing to do with MP3 @320kbps either. That is all depending on if LOW-PASS filter is turned on (default) or not.

But in any case, if you compare this FLAC to a MP3 at 320kbps with low-pass turned off, you'll still see that my "FLAC" is still superior.

By that logic, MP3s are lossless as they can get up to 22khz as well.

Also, that version has a soft cut-off at 12khz. It's softer than my cut-off at 17khz, but still a cut-off. So, are we going to argue which ones' better?

my versions are true lossless what the f you talking about 22ghz think you need to learn the difference, mines better fact

I'll leave that to others to judge...

I'm not saying that my rip is anything near perfect, but to claim its not "true" lossless is not, in fact, correct.

Ian being unnecessarily combative as per usual. Q91 is right, frequency is not the one determining factor of lossless vs lossy. Check out this MP3:
If I had converted it to FLAC, it could pass as lossless just based on the frequency alone. But it wouldn't be since the source was a lossy MP3 file.

Thanks to all for you uploads, but this is what I see when I rip my vinyls, no cuts and easy over 20 Khz.
I don't know about filters, but in my opinion the "rips" are "rips", as they sound, after that everyone chooses to add or not any filter on eq.
I talked with DJ Ninu, who is a producer, about frequency in master tracks he did. He, as lot of other producers, cut the frequency to improve the sound, I did not understand it at all but it's beacause of that I said to check with speq the vinyl rips, not the digital tracks, because I am not sure to confirm the quality of sound with speq.
Excuse my english, and hope somebody could confirm how to check real quality of files.
Thank you;;

This one sounds the best. Every other upload sounds muted, like a tape-to-tape recording.

I'm just posting these to show various ways of detecting fake or good files. All these examples are taken from SPEK and Foobar with the Spectrogram viz.

Low-pass filters are usually used to force the encoder (ie LAME.DLL) to save more Bitrate for frequencies below 17 or 19khz. Hence why some mp3s might see a cut-off around these frequencies or not. Some MP3 (as in Example 2) might not see a cut-off, but frequencies above 20 usually tend to see worse than WAV/FLAC. In most cases the encoder can detect what the track needs.

What I call artifacts are compression happening to the sound. You have seen the squares on a low quality video on YouTube, right? This works similar on lossy codecs like MP3.

Example 1. Vinyl rip, saved to MP3 (CBR 320kbps with no custom settings)
This has clear signs of a low-pass (in this example, the low-pass got set to 19khz) and compression artifacts at the higher frequencies.

Example 2: Digitally sold MP3 from a defunct mp3 store (320kbps)
This is what a really good encoded MP3 should look like. I'm not certain if low-pass filter was turned off or not, but it might look like this because the track isn't over-mastered.

Example 3: Digitally WAV from very recent. (FLAC)
Same song as in Example 2, but from a different place. Barely any difference from the mp3, other than more sound above 20khz on the intro.

Example 4: Vinyl rip, saved to FLAC
This is mostly to show that I can make good vinyl rips. It just happened that my rip of PL008 happen during a time I had different settings.

The artifacts you mention is one of the attributes of lossy compresion or lossy samples used in a track. But the spectrograms you provided doesn't allow quickly discover the artifacts.
Look at the zoomed 2-seconds spectrograms (created with SoX) and you'll see them clearly:

creating zoomed specs with SoX: sox input.flac -n remix 1 spectrogram -X 500 -y 1025 -z 120 -w Kaiser -S 1:00 -d 0:02 -o output.png

FYI, Spek doesn't show actual lossy spectrograms, it transcodes to wav to show mp3's upscaled version of it. Can't really dig into nuances with those defualt-sized (tiny) screenshots except obvious details like low-pass filter or general density/richess drop in >16 kHz range. Use some proper stuff like Adobe Audition.
Does your ripping equpment is really so poor that best it can rip is with CDDA (44 kHz/16 bit) quality? Or maybe it's actually ripped with much better (like 192 kHz/24 bit) quality, gets bit of editing/normalizing/remastering and _then_ it's up to you (to resample/bit reduce it to this conventional/casual standard that can be done in quite a bit of ways/options? There's a thing called lowpass filter transition band/bandwidth that can be tuned to smoothly start killing frequences beyond the filter's set limit, not like almost instantly kill 'em as in mp3s. This thing alone can produce very different-looking spectrums and still they all'll be lossless. Anyway it's vinyl we're dealing with here, so there's mostly noise in ~18 kHz up to "oh look my spectrum is cool, it reaches the chosen sample rate's limit (i.e. 22,05 kHz for 44,1 kHz)" range

I can't remember what settings/hardware I had at the time between 2009 and 2012, because before and after that my rips can easily go up to 20khz without cut-offs (unless the vinyl was pressed that way).

As for spek, I only used it in my examples to show the overall songs quality. And it can almost show mp3 artifacts, especially on tracks from Remix Reloaded or early 24/7 Hardcore labels like Warped and Undeground Recordings (if you fullscreen it). The spectrogram from foobar2k was meant to show it in more detail in an application most probably have more readily available.
