Who invented mp3?

MP3 file is the abbreviation of MPEG Audio Layer3, which is a standard for audio sampling and compression. MP3 technology originated from the doctoral thesis of a German young man (Karlheinz Brandenburg). On July 14, 1995 (European time), the Fraunhofer Institute in Germany decided to use mp3 as the suffix for music format files using the MPEG standard Audio Layer3 specification. MPEG Audio Layer 3 encoding officially became a standard in 1992.

Fraunhofer Institute research scholar Juergen Zeller officially named mp3 ten years ago today, and today, this letter is retained by the institute.

☆Karlheinz Brandenburg, the father of MP3

The contribution of 46-year-old Karlheinz Brandenburg is of epoch-making significance. This technology has made digital music truly popular and has also contributed to online music services. With the emergence of MP3, it can be said that without MP3, there would be no portable MP3 player that is lighter and has a huge capacity, and there would be no Napster for which countless people are crazy...

As early as 1980, Brandenburg was still working in the Electronic Engineering Department While studying in the department, he began to study digital music compression technology. At that time, it took computers 10 hours to decode a digital music file that was about 1 minute long. However, with the rapid improvement of computer computing 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 group pointed out that providing MP3 player software for free download will allow this new standard to gain a place on the Internet as soon as possible, and this will also give birth to online music exchange activities. According to a survey by Searchterms.com, MP3 was once the hottest search keyword on the Internet.
