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 the charter is kept by the Institute. ☆Karlheinz Brandenburg, the father of MP3 The contribution of Karlheinz Brandenburg, 46, is momentous. This technology has made digital music really popular and has also contributed to the rise of online music services.

It took a computer 10 hours to decode a digital music file about 1 minute long, but with computing speed increasing rapidly, a Brandenburg-led research group finally formulated the MP3 standard in 1995, which can perform time compression. real. of digital music. . The MP3 research group notes that free MP3 player software downloads could give the new standard an early place on the Internet, which has also led to online music sharing.
