Dolby Laboratories, Inc. (NYSE: DLB), often shortened to Dolby Labs, is an American company specializing in audio noise reduction and audio encoding/compression. Dolby licenses its technologies to consumer electronics manufacturers.

Dolby Labs was founded by American Ray Dolby in Great Britain in 1965. He moved the company to the United States (San Francisco, California) in 1976. The first product he made was Type A Dolby Noise Reduction, a simple compander. One of the features that set Dolby's compander apart was that it treated only the quiet sounds that would be masked by tape noise. Dolby marketed the product to record companies.

Dolby was persuaded by Henry Kloss of KLH to manufacture a consumer version of his noise reduction. Dolby worked more on companding systems and introduced Type B in 1968.

Dolby also sought to improve film sound. As the corporation's history explains:^{[citation needed]}

The first film with Dolby sound was A Clockwork Orange (1971), which used Dolby noise reduction on all pre-mixes and masters, but a conventional optical sound track on release prints. Callan (1974) was the first film with a Dolby-encoded optical soundtrack. In 1975 Dolby released Dolby Stereo, which included a noise reduction system in addition to more audio channels (Dolby Stereo could actually contain additional center and surround channels matrixed from the left and right). The first film with a Dolby-encoded stereo optical soundtrack was Lisztomania (1975), although this only used an LCR (Left-Center-Right) encoding technique. The first true LCRS (Left-Center-Right-Surround) soundtrack was encoded on the movie A Star Is Born in 1976. In less than ten years, 6,000 cinemas worldwide were equipped to use Dolby Stereo sound. Dolby reworked the system slightly for home use and introduced Dolby Surround, which only extracted a surround channel, and the more impressive Dolby Pro Logic, which was the domestic equivalent of the theatrical Dolby Stereo.

Theatre (in American English usually theater) is a collaborative form of fine art that uses live performers to present the experience of a real or imagined event before a live audience in a specific place. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music or dance. Elements of design and stagecraft are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek θέατρον (théatron, “a place for viewing”) and θεάομαι (theáomai, “to see", "to watch", "to observe”).

Modern Western theatre derives in large measure from ancient Greek drama, from which it borrows technical terminology, classification into genres, and many of its themes, stock characters, and plot elements. Theatre scholar Patrice Pavis defines theatricality, theatrical language, stage writing, and the specificity of theatre as synonymous expressions that differentiate theatre from the other performing arts, literature, and the arts in general.

Andrea Bocelli, OMRI, OMDSM (Italian pronunciation: [anˈdrɛːa boˈtʃɛlli]; born 22 September 1958) is an Italian tenor, multi-instrumentalist and classical crossover artist. Born with poor eyesight, he became blind at the age of twelve following a football accident.

Since winning the Newcomers section of the Sanremo Music Festival in 1994, Bocelli has recorded thirteen solo studio albums, of both pop and classical music, two greatest hits albums, and eight complete operas, selling over 75 million records worldwide. Thus, he is the biggest-selling solo artist in the history of classical music and has caused core classical repertoire to "cross over" to the top of international pop charts and into previously uncharted territory in popular culture.

In 1998, he was named one of People Magazine's 50 Most Beautiful People. In 1999, his nomination for Best New Artist at the Grammy Awards marked the first, and so far only time a classical artist had been nominated in the category, since Leontyne Price, in 1961.The Prayer, his duet with Celine Dion for the animated film The Quest for Camelot, won the Golden Globe for Best Original Song and was nominated for an Academy Award in the same category. With the release of his classical album, Sacred Arias, Bocelli captured a listing in the Guinness Book of World Records, as he simultaneously held the top 3 positions on the US classical albums charts. Six of his albums have since reached the Top 10 on the Billboard 200, and a record-setting 8, have topped the classical albums charts in the United States.
