Can I Mix It?

Streaming Audio
1

Detect fake WAVs/FLACs and low-quality re-encodes before gigs or releases.

Imagine you have a low-resolution photo. What would you get if you amplified it?

or

Think about a blurry picture. If you zoomed in on it, what would you see?

Sorry I don’t understand where you want to go ?

:smiley:

This just shows that often the content does not match the container.

For example, on Qobuz, there is almost never anything above 48 kHz.

Etc.

What do you mean? Can you mix what? It is certainly possible to have some files flac and others wav and for a streamer to play both, but what is your query re fakes? Do you mean upsampled from low res copies? And by gigs do you mean bootleg recordings, perhaps poor, then being sold masquerading as the legitimate file?

I don’t want to mix anything.

This site just lets you:

Drop an audio file. Get a score from 0 to 100 and a full breakdown of every quality issue detected. Know instantly if your WAV is actually a WAV, or a re-encoded MP3 in disguise.

Detected issues:

  • Fake lossless (WAV/FLAC hiding a lossy re-encode)
  • Spectral cutoff — effective frequency bandwidth
  • Spectral wall — hallmark of lossy encoding
  • Upsampling detection
  • Clipping events
  • Dynamic range (TT DR method)
  • True peak (ITU-R BS.1770, 4× oversampling)
  • LUFS loudness (EBU R128)
  • Stereo field — correlation, mono duplicate, suspect stereo
  • Sub-bass phase issues (<120 Hz)
  • Pre-echo artifacts
  • Codec blockiness
  • Noise floor

that’s all :wink:

Sorry for the poor presentation I may have given.

I just selected half a dozen albums at random on Qobuz. Two were 48, three were 96 and one was 192. All were 24 bit.

but when you look inside a 96KHz file (with an app or this site), most of them have nothing above 48KHz. it’s the same for 192KHz files.

for example : Nala Sinephro|Endlessness 24/96
track 7 is upsampled from a 320kbps MP3
track 10 is upsampled from a 160 or 256kbps MP3
