The Hafler circuit is a passive electronics circuit with the aim of getting derived surround sound or ambiophony from regular stereo recordings without using costly electronics. Such circuits are generally known as matrix decoders. The Dynaquad system works using similar principles. [1]
3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener.
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener (surround channels). Its first application was in movie theaters .
A four channel quadraphonic diagram showing the usual placement of speakers around the listener. Quadraphonic (or quadrophonic, also called quadrasonic or by the neologism quadio [1] [formed by analogy with "stereo"]) sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space.
10.2 is the surround sound format developed by THX creator Tomlinson Holman of TMH Labs and the University of Southern California (schools of Cinematic Arts and Engineering). ). Developed along with Chris Kyriakakis of the USC Viterbi School of Engineering, 10.2 refers to the format's slogan: "Twice as good as 5
Darts is a competitive sport in which two or more players bare-handedly throw small sharp-pointed projectiles known as darts at a round target known as a dartboard. [2]Points can be scored by hitting specific marked areas of the board, though unlike in sports such as archery, these areas are distributed all across the board and do not follow a principle of points increasing toward the board's ...
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 Digital, Dolby Pro Logic II, DTS, SDDS, and THX are all common 5.1 systems. 5.1 is also the ...
A virtual surround system must provide a means for 2-dimensional imaging of sound, using some properties of the human auditory system. The way that the auditory system localises a sound source is a topic that is studied in the field of psychoacoustics. Thus, virtual surround systems use knowledge of psychoacoustics to "trick" the listener ...
