Dolby Labs was founded by Ray Dolby (1933–2013) in London, England, in 1965. [5] In the same year, he invented the Dolby Noise Reduction system, a form of audio signal processing for reducing the background hissing sound on cassette tape recordings. [6]
Callan (1974) was the first film with a Dolby-encoded optical soundtrack. The first true LCRS (Left-Center-Right-Surround) soundtrack was encoded on the movie A Star Is Born in 1976. In fewer than ten years, 6,000 cinemas worldwide were equipped to use Dolby Stereo sound. Dolby then developed a digital surround sound compression scheme for the ...
A Dolby noise-reduction system, or Dolby NR, is one of a series of noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. [1] The first was Dolby A, a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market ...
The sound bar utilizes analysis of a room's reflective characteristics to enable a single-unit 5.1.4 setup. [47] On May 17, 2021, Apple Music announced the addition of spatial audio with support for Dolby Atmos and lossless audio. [48] The feature was introduced to Apple Music users on Apple devices starting from June 7, 2021. [49]
The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full-bandwidth channels and one low-frequency effects channel (the "point one"). [2]
Dolby Stereo is a sound format made by Dolby Laboratories.It is a unified brand for two completely different basic systems: the Dolby SVA (stereo variable-area) 1976 system used with optical sound tracks on 35mm film, [1] and Dolby Stereo 70mm noise reduction on 6-channel magnetic soundtracks on 70mm prints.
A competing system, dbx, invented by David Blackmer, [36] also found success in professional audio. [37] A simpler variant of Dolby's noise reduction system, known as Dolby B, greatly improved the sound of cassette tape recordings by reducing the especially high level of hiss that resulted from the cassette's miniaturized tape format.
The first and simplest method is using a surround sound recording technique—capturing two distinct stereo images, one for the front and one for the back or by using a dedicated setup, e.g., an augmented Decca tree [20] —or mixing-in surround sound for playback on an audio system using speakers encircling the listener to play audio from ...
