For so many years I was thinking that Mp3 sounds inferior because it was missing frequencies above certain level. This view seems to be wrong in light of what Grant Bridgeman said in his article that, I quote, " A good mp3 achieves a compression ratio of about 10:1 compared to an original 44.1kHz/16-bit audio file, and although some of the information has been lost, the audio quality is still acceptable to most people. This is because the algorithms are written specifically to take how we hear into account, removing audio data that our ears do not perceive as being of importance.
However, we can still hear the difference, as mp3s can sound hollow, thin and lacking sparkle. This is because that ‘un-perceivable’ information has been removed and our brains can no longer filter the sound in the same way as we would with the original recording."
So is Mr. Bridgeman suggesting even though we do not perceive the sound but it is still important?
