MP3 file is the abbreviation of MPEG Audio Layer3, which is the standard of audio sampling and compression. MP3 technology originated from the doctoral thesis of a German youth (Karlheinz Brandenburg). 1July, 995 14 (European time), the Fraunhofer Association of Germany decided to use mp3 as the suffix of the music format file using MPEG standard audio layer 3. The third layer coding of MPEG audio has become the standard in 1992. Juergen Zeller, a researcher at Hof College in Flawn, was officially named mp3 ten years ago today. Today, this letter is kept by the college. ☆ Karlheinz Brandenburg ☆ The contribution of Karl Heinz Brandenburg, the father of MP3, at the age of 46, is of epoch-making significance. This technology has made digital music really popular, and also contributed to the emergence of online music services. Without MP3, there would be no portable MP3 with huge capacity, and there would be no countless Napster ... crazy about it ... As early as 1980, Brandenburg began to study the compression technology of digital music when he was still studying in the Department of Electronic Engineering. At that time, it took 1 0 hour for a computer to decode a digital music file with a length of about1minute. However, with the rapid improvement of computer operation speed, the research team led by Brandenburg finally formulated the MP3 standard in 1995, which can realize real-time compression of digital music. The MP3 research team pointed out that the free download of MP3 player software can make this new standard occupy a place on the Internet as soon as possible, which also gave birth to online music exchange activities.
