Compressing, Transferring and Storing Audio Data

Good Essays
Today’s most popular solution for compressing, transferring and storing audio data is MP3 technology. There are similar technologies for sampling and compressing audio data but MP3 remains the most popular because it is versatile, high performing and flexible. MP3 as we know it today, is the product of collaborations through the years by many organizations. If we had to narrow down the most important people involved in it’s development, the two most important names would be Dieter Seitzer and Karlheinz Bradenburg. Initially, in the 1970s, Dieter Seitzer, a professor from Erlangen-Nuremberg University was researching the problem of compressing audio data for telephone line transmission. He brought together a group of students as well as other scientists to do research and solve this challenge. One of his students , named Karlheinz Bradenburg, proposed an idea of exploiting the mechanism of human hearing and its limitations. Later on, in his doctoral theses, Karlheinz Bradenburg included algorithms that were later incorporated in todays MP3 technology. Most importantly were his method of scanning and removing sounds that were in audible to humans. In 1988 the ISO convened and called for a standard in audio and video encoding. This call created the Moving Picture Experts Group (MPEG). Contributions to the group came from various corporations, research organizations and individual scientists. This increase of contributions and collaboration from members of the MPEG
