Keith Devin, executive director of the Centre for the Study of Language and Information at Stanford University (California), states that Mp3 downloading involves streams of numbers, computed using a calculus-based technique developed by French mathematician Joseph Fourier in the19th century. MP3 (MPEG-1 Audio Layer-3) is a standard technology and format for compression a sound sequence into a very small file (about one-twelfth the size of the original file) while preserving the original level of sound quality when it is played. Mp3 format was invented and standardised in 1991 by a team of engineers working in the framework of the ISO/IEC MPEG audio committee under the chairmanship of Professor Hans Musmann (University of Hannover - Germany).
