Dolby Atmos is a surround sound technology developed by Dolby Laboratories.It expands on existing surround sound systems by adding height channels, interpreted as three-dimensional objects with neither horizontal nor vertical limitations.
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
A soundbar, sound bar or media bar is a type of loudspeaker that projects audio from a wide enclosure. It is much wider than it is tall, partly for acoustic reasons, and partly so it can be mounted above or below a display device (e.g. above a computer monitor or under a home theater or television screen).
5–10 0-7 EAN-13 code (possibly in binary-coded decimal) 11 0-3 4–7 Undefined; padding on 13-digit EAN code 12–13 0-7 Undefined 14 0–3 4-7 ISRC (encoding unclear; ISRC is 2 alphabetic, 3 alphanumeric and 7 numeric, which is 26 2 × 36 3 × 10 7 ≈ 2 48.164 and so obviously fits into 7.5 bytes, but a naive 5 ASCII + 7 BCD would be 8.5 bytes)
10.2 is the surround sound format developed by THX creator Tomlinson Holman of TMH Labs and University of Southern California (schools of Cinema/Television and Engineering). Developed along with Chris Kyriakakis of the USC Viterbi School of Engineering , 10.2 refers to the format's promotional slogan: "Twice as good as 5.1".
A prototype for five-channel surround sound, then dubbed "quintaphonic sound", was used in the 1975 film Tommy. [6]5.1 dates back to 1976, [7] when Dolby Labs modified the track usage of the six analogue magnetic soundtracks on Todd-AO 70 mm film prints.
Dolby Pro Logic is a surround sound processing technology developed by Dolby Laboratories, designed to decode soundtracks encoded with Dolby Surround.The terms Dolby Stereo and LtRt (Left Total, Right Total) are also used to describe soundtracks that are encoded using this technique.
HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.
