Peter Scheiber is considered to be the originator of the matrix format, a basic mathematical formula used to convert four channels into two which is what most matrix four channel systems are based on. He is also a musician and audio engineer.
|Occupation||Founder of Scheiber quadraphonic system|
In matrix quadraphonic systems four channels are converted (encoded) down to two channels. These two matrixed channels are recorded onto 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 loudspeakers.
Scheiber is also the inventor of the 360-degree spatial decoder.
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 Music Center and played with the Civic Orchestra of Chicago. Later, as a professional, he was a member of orchestras in Ottawa and Texas.
In 1967 Scheiber, then a 32-year-old bassoonist, came up with the idea of encoding four channels of sound in two channels and decoding them back to four. He sold a patent licence to CBS.
