Super Audio CD (SACD) is a read-only optical disc for audio storage, introduced in 1999. It was developed jointly by Sony and Philips Electronics, and intended to be the successor to their Compact Disc (CD) format. While the SACD format can offer more channels (e.g. surround sound), and a longer playing time than CD, research published in 2007 found no significant difference in audio quality between SACD and standard CD at ordinary volume levels.[1]

Having made little impact in the consumer audio market, by 2007, SACD was deemed to be a failure by the press.[2] A small market for SACD has remained, serving the audiophile community.[3]


The Super Audio CD format was introduced in 1999.[2] Royal Philips and Crest Digital partnered in May 2002 to develop and install the first SACD hybrid disc production line in the United States, with a production capacity of three million discs per year.[4] SACD did not achieve the same level of growth that compact discs enjoyed in the 1980s,[5] and was not accepted by the mainstream market.[6][7][8]

The first broadcast of a SACD Disc on BBC Radio was in March 2000. The programme was an interview between Eric Kingdon (Sony), Colin Mackenzie (Hi-Fi Corner) and Kit Frazer (BBC Radio Scotland). The disc played was Mariah Carey 'Mariah'.[9][not in citation given]
