How to compress an mp3 so that it takes up less space on the hard drive?
An mp3 occupies one eleventh of the original on average.
Sometimes people don’t realize that literally compressing an mp3 means making the data take up a lot less space on the hard drive.
A WAV usually takes up a lot of space, especially because it saves as much information as possible.
A long time ago it was determined that the human ear was not very precise and therefore there were many sounds that could not be heard.
Based on an analysis of all this information about the peculiarities of human perception with respect to sound, an algorithm could be achieved to remove all this information, which was contained in the original WAVs, but since it could be removed without major impact, achieved that the compression was not only of the zip type, but also auditory.
The result was surprising, since an mp3 managed to occupy an average of one eleventh of the size of the original audio with hardly any differences being perceived.
Over time this has improved even more and it has been achieved, according to many tests carried out by many different researchers, to determine that an mp3 with a bitrate of 192 or more and a samplerate of 410 or more is almost impossible to distinguish from some audio without lost for 99.99% of people.
Especially if we consider the quality of equipment and headphones available today.
