.7 Abstract This report details the impact MP3 technology has on present day sound systems. It takes a brief look at the history of the system that was developed for something other than hi-fi, but almost by accident became the future of compression in sound and hi-fi systems. It outlines as simple as possible in general terms how the system works and the different types of compression formats associated with MP3 technology. The report also gives a brief insight into the complicated legal issues surrounding the system and the companies involved with it. Does the technology of MP3 have an impact on the systems in the shops today? There are some suggestions in this report that might answer that question. Finally the report concludes with some possible propositions that the companies which are trying to put down the uses of MP3 could use it to their advantage. Introduction This is part one of a two part assignment on Sound and Hi-Fi systems which was chosen as an elective module for a university degree course. This part of the assignment is a report on the introduction of MP3 technology and looks at such aspects as how it works and the affect it has on living today and the impact it has on sound based systems which are been offered for sale through various outlets to the public on a daily basis. MP3 TECHNOLOGY History Work first began on developing a high quality, low bit-rate audio format at the Fraunhofer Institute in Germany in 1987 for use in motion pictures [2]. MP3, which is short for Moving Picture Experts Group, Audio Layer III was developed in the early 1990s by the same institute, but this application was not a very successful [1]. Tomislav Uzelac, a developer at the Advanced Multimedia Products and who proved to be a real genius in understanding and optimizing codecs [3], created the AMP MP3 Playback Engine In 1997. This was regarded as the first prime-time MP3 player [2]. The AMP engine had not long been introduced to the Net when Justin Frankel and Dmitry Boldyrev, a couple of university students, took the engine and added a Windows interface and called it "Winamp" (they also more recently created Mac AMP). This was offered up as a free music player on the Internet in 1998 [2] and so the MP3 craze began and changed the way music was collected, distributed and listened to. What is MP3? In simple terms MP3 Technology is a way of taking very large digital data files and making them smaller in size.
