Manufacturer of various patented systems for processing sound. Originally (pre-digital) concerned with reducing tape hiss, they now concentrate on stereo and surround sound.
Trademarked noise reduction systems and technology by Dolby Laboratories to improve the performance and fidelity of audio recording, playback, and transmission.
Dolby Laboratories trademark on a type of noise reduction. Dolby A and C are used on professional equipment; Dolby B is used on consumer equipment. If a tape is recorded and played back using Dolby, there will be less background tape hiss.
See Dolby® Digital; Dolby® Pro Logic®; Dolby ProLogic® II; Dolby® Stereo; Dolby® Surround; Dolby® B, C and S
Surround - Dolby laboratories developed surround sound which distributes audio signals to speakers placed around the room to create an effect of directional and ambient sound. There are several Dolby products the most well known of which are ProLogic and Dolby Digital. For more information, see our article on surround sound.
United States electrical engineer who devised the Dolby system used to reduce background noise in tape recording
Patented noise/hiss reduction systems developed by Ray Dolby to improve audio recording quality. Dolby A is commonly used in television; Dolby B was developed for use in consumer electronics.
a noise reduction system that was developed by Dolby Laboratories to reduce tape hiss on cassette decks. 'Dolby B' is less advanced than 'Dolby C', which is less advanced than 'Dolby S'.
Dolby Laboratories: the company that developed Dolby Noise Reduction for magnetic audio media.
Trade name for a series of noise reduction systems that have become standard on many tape playback machines. Many film soundtracks are produced using this process. Different varieties are found from Dolby B on most personal cassette players, to Dolby SR and Digital, the current state of the art for cinema.
an audio noise reduction system which reduces tape hiss.
The manufacturer (and trademark) of audio noise reduction systems and other systems that improve the performance and fidelity of audio recording, transmission, and playback.
The first, and still the most widely used, tape noise and reduction system, invented by Or Ray Dolby. During recording, this device raises the high frequencies (where most background hiss is present) above normal. On playback these are reduced to normal perspective once more and the hiss is greatly reduced.
A Method of noise reduction for audio signals created by Ray Dolby.
Dolby A, B, C and Dolby SR are electronic processing that are used to increase the signal-to-noise ratio and reduce unwanted frequencies. This process specifically targets the frequency range of the tape hiss that is inherent in the recording of analog signals.
