I saw Jay-Z's music service launched last night and I found one of their mini-games online asking you to spot the difference between "high quality" music and "high fidelity" music as that's its unique selling point.
Terms are defined here:
How good is the sound quality on TIDAL?
Normal quality: 96 kbps (AAC+)
High quality: 320 kbps (AAC)
HiFi: Flac 1411 kbps - Lossless (16/44.1 khz)
How do I change the quality? Go to ‘Settings’ to select sound quality.
Personally, I couldn't hear a difference (but scored 2 out of 5 from pure guess work) so it's tough for me as a user to want to sign-up - especially when Spotify is half the price.
So my question is: what's the physical difference between high quality and high fidelity? Is it a higher bitrate or something more?
