" MP3 vs. WAV "
One is 320kbps tops, the other 1400-4000kbps. The difference is night and day to an untrained ear. I have been teaching a friend how to hear nuances in music for a couple of years now. He usually can't hear small artifacts in music that I can, especially forward, reserved, sound staging etc.
Even he can INSTANTLY tell the difference between WAV and MP3 files, you'd have to be tone deaf and under 25 not to hear a difference. That's been my point for years though, dumbed down ears. I have had week long arguments with artists regarding production and engineering costs. they say, hell if people can't hear the difference why bother with another 40 hours in the studio engineering it? My answer is always, because "I KNOW". I don't put out crap.
So may do though, low quality CD's for pennies a piece, low quality engineering, poor compression leaving all kinds of crap in the mix etc. But kids buy it, rip it to an inaudible format and listen to it on thier iToys. The masses have be dimbed down so much they don't even know the difference when they hear it.
No difference between WAV and MP3? You may as well be completely deaf, you're most of the way there already. ANY sound engineer, speaker designer of audio buff can INSTANTLY tell such an obvious difference.
