What is MP3?
MPEG-1 Audio Layer 3, better known as MP3, also known by its spelling emepetrés is a compressed digital audio format with loss developed by the Moving Picture Experts Group (MPEG) to form part of Release 1 (and later extended in version 2) of the MPEG video format. His name is short for MPEG-1 Audio Layer 3.
History
This format was pioneered by Karlheinz Brandenburg, director of electronic media technologies at the Fraunhofer Institute IIS, part of the Fraunhofer-Gesellschaft - a network of German research centers - which together with Thomson Multimedia controls the bulk of patents related to MP3. The first was recorded in 1986 and several more in 1991. It was not until July 1995 when Brandenburg was first used by the. Mp3 for MP3 files related to that stored in his computer. A year later entered the institute for patents 1.2 million euros. Ten years later this figure has reached 26.1 million.
The MP3 format became the standard for streaming audio and audio compression quality (with loss hi-fi) thanks to the ability to adjust the compression quality, proportional to the size per second (bitrate) and therefore the final file size, which could come to occupy 12 and even 15 times less than the original uncompressed file.
It was the first audio compression format popularized by the internet, as it made possible the exchange of music files. The lawsuits against companies like Napster and AudioGalaxy are the result of the ease with which they share these files.
After the development of autonomous players, laptops or integrated music channels (stereo) MP3 format goes beyond the world of computing.
In early 2002, other compressed audio formats such as Windows Media Audio and Ogg Vorbis are becoming massively included in programs, operating systems and stand-alone players, which led to expectations that the MP3 was gradually falling into disuse, in favor of other formats, such as these, of much better quality. One of the factors influencing the decline of MP3 is that is patented. Technically it means that its quality is inferior or superior, but prevents the community to continue improving and can make you pay for the use of a codec, this is the case with MP3 players. Still, in early 2007, the mp3 format is still the most used and enjoyed more success.
