Brandenburg finishes his doctoral thesis on the OCF algorithm Optimum Coding in the Frequency Domain , a codec exhibiting a number of characteristics of the eventual mp3 technology, like a high frequency resolution filter bank, non-uniform quantization, Huffman coding, and its side information structure.

That way, transmission of music in real-time over telephone lines could be achieved. MPEG in total received 14 proposals for audio coding. In this way, transmitting speech and music reliably via ISDN between broadcasting studios becomes the first real application of the Fraunhofer IIS audio coding algorithms.

In its audio section, a generic family of three codec formats Layer 1, 2, 3 is specified. Being the most efficient of the three codecs, Layer 3 soon becomes a popular way to store music on the relatively small hard disk drives of PCs and to transfer music files over the Internet through The first generation of one-chip mp3 decoders by Micronas are introduced in a Solid State Player.

Shortly after, Fraunhofer IIS develops the prototype of an mp3 player. This first portable music player without moveable parts saves about a minute of an mp3 track and proves the suitability for daily use. The Fraunhofer-Gesellschaft and Thomson establish a joint license program.

Already in , directly after the standardization, the first companies license mp3. In an internal poll, Fraunhofer researchers unanimously vote for. In the same year, Fraunhofer provides a first PC based Layer 3 codec as shareware. Customize Select the topics that interest you:. Love and Sex. Healthy Living. Pop Culture. Book Swipe Shop.
