It’s been a while since some people say or post that mp3 is dead.<\/p>\n

It is an impulsive and hardly credible assessment.
\nThe mp3 emerged as an urgent need to save space, because the WAV file is very large and there were those who paid attention to the functioning of the human ear and soon discovered some things they could do to save space, in addition to zip compression.<\/p>\n
He first noticed that there was a lot of information about frequencies that we humans can’t hear and that this information took up a lot of space, so removing it would not affect the sound quality and would save space.<\/p>\n
Then I noticed that there is a phenomenon called audio masking which meant that if we hear a sound in a range of frequencies and seconds or milliseconds later we get another sound in nearby frequencies, we won’t hear the second ones… so we can remove them. .. and so, there is a whole series of phenomena typical of human hearing that are used by mp3 in an intelligent way.<\/p>\n
But there are also the compression settings that each one uses, such as the bit rate and that many times DOES affect the sound quality.<\/p>\n
Experiments with professional musicians have shown that even a trained ear cannot distinguish a GOOD mp3 from a lossless file.<\/p>\n
Mp4Gain is capable of generating high quality mp3, mmp4, flac, wav, etc.<\/p>\n","protected":false},"excerpt":{"rendered":"
