Deezer is a music streaming platform, which offers (amongst others) a package called Deezer HiFi. What's so different about it?
Listen to FLAC music in High Fidelity sound as if you were right in the recording studio.
And although a lot (or most of) the advertised HiFi catalog is actually loseless quality (FLAC), there are of course and some exceptions: in this case the album Schizo Deluxe (2005) from Annihilator.
First from Deezer, using spek utility we can display the spectogram and we can notice some cut right below 20 kHz and a lot of noise filling in the rest of the frequency range.
The second snapshot is from a CD rip for the same track:
Now it's not that clear if the first snapshot is actually a pumped up mp3 at 320 kbps done intentionally by the service, or just some low quality input. But if you look around, you will find quite some similar examples.
