In 1968 Dolby B was developed and quickly found its use in the Philips Compact Cassette, which had become the new consumer medium for music. In 1981 Dolby C was an improvement designed for the consumer market, but it also was used in professional video equipment. In 1986 Dolby SR was introduced for professional sound recording. It is a common feature that the equipment has to be in a good state of calibration in order to obtain the advantages of these compander systems.[br]Principal Honours and DistinctionsOBE 1986.GB-N
