MP3's? can someone please explain how taking 90% of a recording away and leaving only that last 10% of the original information doesn't change the quality of the reproduction?
I'm sorry but 128bps mp3s suck very badly to someone who listens to music many hours a day.
Depends on the encoding. Some 128kbps mp3s are so harsh I can't listen to them through, others don't assault my ears. OTOH if you listen to an mp3 player through cheap earbuds, you may not notice a difference.
I can't explain how. I do know that most people can't distinguish a VBR MP3 at -V0 (~245 kbps) or -V1 (~225 kbps) from the original in ABX blind tests. Again,
most people, not everyone.
