'''Peter Scheiber''' is a classically trained [[musician]] and [[audio engineer]]. He is considered to be the originator of multichannel ''matrix'' audio formats, a mathematical formula used to convert four audio channels into two and back again.
Scheiber is also the inventor of the 360-degree spatial decoder.<ref>''[[Indianapolis Monthly]]'', May 2007 - Page 103 - [https://books.google.com/books?id=Nh0DAAAAMBAJ
In matrix [[Quadraphonic sound|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 stereo]] transmission medium - in most cases a vinyl record - these are decoded back to four channels and reproduced via four loudspeakers.<ref>{{cite journal

In 1967 Scheiber, then a 32-year-old [[bassoon]]ist, came up with the idea of encoding four channels of sound in two channels and decoding them back to four. He sold a [[patent license]] to CBS.<ref>Business Highbeam [https://web.archive.org/web/20160309021432/https://business.highbeam.com/392705/article-1G1-9151572/quad-sound-reincarnated Quad sound, reincarnated.

==Legal battle==
As of October 2003, the 68-year-old Sheiber had more or less become a recluse for eight years due to his legal battle with Dolby Laboratories. This was over Dolby's development of a surround sound system for motion picture industry which was based on his invention. After some difficulties, he was able to secure some royalty payments from Dolby and Harman International which lasted from 1983 to late 1994. He received over a million. The companies eventually stopped paying Sheiber as they claimed that the patents had expired and wasn't due any more money. In June 2002, Seventh Circuit Appeals Judge Richard Posner ruled against him which was his biggest defeat.
