Digital Music – Maximum Sound In Minimal Space 0
Time was that you had to visit a record store to get the music you wanted. Later, a membership to Columbia House meant you could easily order music from the comfort of your own home, but you had to wait. Technology advanced and media got smaller, delivery faster. Vinyl records were replaced with magnetic tape, cassettes and 8-tracks, then compact discs and even smaller compact discs. Silly me, I thought other than making the disc smaller what could possibly replace CD’s? Well, as usual, technology has kept the pace and left me flailing in it’s dusty wake. Digital music has revolutionized the way we acquire and listen to music. Now when you want an album or even a single song, it’s as easy as pointing and clicking, waiting a few seconds for the download and you’re rockin’ and rollin’. Or groovin’ to the tunes. Or gettin’ down with the beat, etc., etc.

Roots In The Fatherland
MP3, or MPEG Audio Layer III, got its start in Germany in 1987 when the Fraunhofer Institut began doing research on the subject and started the EUREKA project EU147. Karlheinz Brandenburg, sometimes called The Father of MP3, explains how MP3 almost never got off the ground. The code, for some reason just would not work. Luckily, just before they were to submit the project to the Moving Picture Experts Group (MPEG) subcommittee, the group that oversees standards for the industry, they found the compilation error that was causing the problems.
A company called Fraunhofer-Gesellschaft now owns the patents and licenses the rights to its use.
The Technology – In Simple Terms
The amount of data or information in just one second of CD quality music is about 1.4 megabits or almost 1 and a half million pieces of information per second. MP3 technology compresses the file, shrinking its
