Peter Scheiber
Nationality American
Occupation Founder of Scheiber quadraphonic system

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.[1][2]

He is also the inventor of the 360-degree Spatial decoder.[3]

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.[4]

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.[5]

Peter Scheiber would eventually take legal action against Dolby Laboratories, Inc., and Dolby Laboratories Licensing Corp for infringement of his patents.[6]
