Peter Scheiber is considered to be the originator of the ''matrix'' format, a basic mathematical formulae used to matrix four channels into two which is what most matrix four channel systems are based on. He is also a musician. Matrix quadraphonic systems are where four channels are converted (encoded) down to two channels. These two matrixed channels are recorded on to tape or vinyl record. Reproduction occurs Via a two-channel transmission medium in most cases a vinyl record, these are decoded back to four channels and reproduced via four loud speakers. He is also the inventor of the 360-degree Spatial decoder.〔Indianapolis Monthly May 2007 Page 103 (Sound Effects by Amy Wimmer Schwarb ) (See caption "Got them surrrounded")〕 ==History== Peter Scheiber was born in Croton-on-Hudson in New York in 1935. He grew up in Peekskill. From an early age, passionate about music and technology, he had a workbench in his bedroom for experimenting with his gadgets. He later earned a scholarship at Tanglewood and played with the Civic Orchestra of Chicago. Later, as a professional, he was a member of orchestras in Ottawa and Texas.〔Indianapolis Monthly May 2007 Page 102, 103 (Sound Effects by Amy Wimmer Schwarb )〕 In 1967, Scheiber, then a 32-year-old bassoonist, came up with an idea of encoding four channels of sound down to two and decoding it back to four. He sold a patent licence to CBS.〔Business Highbeam (Quad sound, reincarnated. (American inventors making money from Japanese televisions and stereos) )〕 Peter Scheiber would eventually take legal action against Dolby Laboratories, Inc., and Dolby Laboratories Licensing Corp for infringement of his patents.〔law.justia.com (293 F.3d 1014: Peter Scheiber, Plaintiff-appellant, v.
