Maths Is Music To Our Ears!

Maths Is Music To Our Ears! Mathematician Keith Devlin has recently pointed out that the Mp3 industry is built upon Maths.

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).
