Everyone knows the term MP3, but few know the technical details behind it or its history. We approach a more detailed presentation of the respective files, in the following section, exemplifying the difference from other types of audio formats, in order to help the readers to know better what they are listening to on their own players.
Why is MP3 so popular? Why did it name an entire product sector, digital audio players being sold under this format name? When did it appear? Who invented it? Does it also have disadvantages? If so, what are the best alternatives, as audio files? We will try to answer all these questions, in the few paragraphs below, taking each one in turn and providing useful information to our readers, but also interesting for those who want to know more than the average person. Let's start with the presentation of the MP3 and a short history of it:
What does the name MP3 actually mean
MP3 is, in fact, the third-party MPEG-2 standard, launched by the Moving Picture Experts Group in 1993, a group of authorities that sets standards for video compression. The peculiarity of these files is the audio compression, they being recorded by reducing (or approximating) the accuracy of certain sound components, considered at the limit of human hearing.
That is, if some sounds are barely perceptible on a high-fidelity recording (such as an audio CD), they will be removed in an MP3, or altered to take up less space on a magnetic disk. Thus, the same song will occupy about 9% compared to its version on compact disc, at a compression rate of 128 kilobits per second.
