>>127290516>An A/B test isn't particularly fair unless the participant is well acquainted with the song at minimumNot for everyone. I can hear lossy encoders working regardless of source material (I'm sure there are cases where I can't, but like the immediately visible lossy visual compression artifacts in JPEG the audio artifacts have been obvious within seconds in every case I've bothered to try).
An anecdote: I once purchased a CD re-release of an album by a famous (RRHoF, hundreds of credits) drummer. Excited to finally hear it at 44.1/16 instead of vinyl, within seconds of pressing play I was appalled at how horrible it sounded.
I contacted the drummer, and asked his assistant what the hell happened - and I said specifically "It sounds like you pressed an mp3?!?"
And the assistant sheepishly admitted that the drummer had lost the original 2-track masters when he moved to a new house, so in fact they *had* pressed a *320kpbs mp3-encoded copy* because that was the best they could find (they also couldn't find any clean copies of the original vinyl).
To the drummer's credit he sincerely apologized to me (not that I had any doubts about his integrity, simply completing the story).
If any of you don't hear a meaningful difference between lossy and lossless formats then I suppose you're lucky economically (though unlucky aurally). You don't have to worry much about how things sound to you.
But people with ears hear the difference, we hear it immediately, and I'd posit the widespread adoption of lossless formats suggests the number of us who can easily hear the difference is very large.
