alt Hacker NewsPretty great demo! It'd be great to see a 128/192 comparison.
I had Tidal many years back, and from the Lossless v Regular I only ever noticed a difference when it came to breathy sounds/etc. I did see that Tidal would burn through like 50GB of data monthly though.
Also - you may want to test some more modern recordings, the microphone/mastering quality of things nowadays is far better than what it was 2 decades ago (despite what some audiophiles may claim)
I’ve done a bunch of testing over the years including a similar test of ‘can people hear mp3 compression’ as well as comparison of mp3 variable bit rate qualities.
In practice, on average playback equipment (by which I mean decent hifi) in an average listening environment most people can’t tell the difference.
But… I’ve also done blind testing with a top mastering engineer on studio speakers and he was able to identifying 48 vs 192 reliably.
Mastering quality was ruined by the battle for perceived loudness. So masters with decent degrees of dynamic range is definitely helpful.
