It all starts in the 70s, in Germany, when a German teacher and his students think of a way to encode music. Dieter Seitzer’s team at the University of Nuremberg manages to develop the first processor capable of compressing audio.
In the 1980s, an agreement was signed between the German university and the Fraunhofer Institute. With more people, the group begins to try to improve the audio encoding algorithms. At the end of the decade, the student Karlheinz Brandenburg presented the OCF algorithm (“Optimal coding in the frequency domain”) in his doctoral thesis.
In 1991, the OCF algorithm was refined and adopted by the MPEG group. MP3 was born, but still without the name we know today.
Only in 1995 was the name MP3 suggested, voted and unanimously approved. Files encoded in MPEG-1 Layer 3 must have the extension “.mp3”. Until now, the codec was only handled by its developers.
At the time, no one knew how successful the format would be, as everyone was excited about the LP, K7, and CD compilation.
But MP3 began to spread like a tsunami through MP3 players, sharing recordable CDs with Internet users and later with recordable DVDs, flash drives, smartphones, and external hard drives.
With the increase in Internet speed and the size of the storage capacity of devices, millions of people can download complete albums in seconds and save them in different places.
Advantages and disadvantages of MP3
ADVANTAGES :
The listener can equalize, increase / decrease the volume, pause / stop and fast forward / rewind the MP3 as if they were listening to a CD.
It requires little RAM to function.
Due to its small size, it can be transported, shared, stored and run in different ways and on different devices.
You can download thousands of songs on the Internet, both free and paid.
It has superior quality to an old radio or K7 transmission.
On the Internet, obtaining it is immediate, unlike physical means, which can wait days to arrive.
It is possible to make a playlist with hundreds of songs and play them without having to change the media / media.
Harms less the environment.
Improvements are possible through audio editing software.
It has metadata with information about artist, album, genre, etc.
DISADVANTAGES:
Conversion may result in low quality, depending on the quality chosen.
An MP3 downloaded from the Internet may have some effects, voices and other changes made to the original audio.
Facilitates piracy, both virtual and physical, damaging copyright.
It has a loss of quality, although minimal, in relation to the CD.
It is intangible, it cannot be touched or smelled.
There is no sense of nostalgia.
Some MP3s have incorrect or missing metadata about the song.
