Masking threshold — The masking threshold is the sound pressure level of a sound needed to make the sound perceptible in the presence of another noice, called a masker . This threshold depends upon the frequency, the kind of masker, and the kind of sound being… … Wikipedia
Auditory masking — occurs when the perception of one sound is affected by the presence of another sound (Gelfand 2004). The term masking is not confined to auditory perception as it can also be used in visual perception tasks.Masking can be simultaneous or non… … Wikipedia
Sound masking — For other uses of masking , see Masking (disambiguation). Sound masking is the addition of natural or artificial sound (such as as white noise or pink noise) into an environment to cover up unwanted sound by using auditory masking. This is in… … Wikipedia
Unsharp masking — is an image manipulation technique now familiar to many users of digital image processing software, but it seems to have been first used in Germany in the 1930s as a way of increasing the acutance, or apparent sharpness, of photographic images.… … Wikipedia
Aperture masking interferometry — is a form of speckle interferometry, allowing diffraction limited imaging from ground based telescopes. This technique allows ground based telescopes to reach the maximum possible resolution, allowing ground based telescopes with large diameters… … Wikipedia
Overshoot (signal) — An illustration of overshoot, followed by ringing and settle time. In signal processing, control theory, electronics, and mathematics, overshoot is when a signal or function exceeds its target. It arises especially in the step response of… … Wikipedia
PEAQ — (Perceptual Evaluation of Audio Quality) is a standardized algorithm for objectively measuring perceived audio quality, developed in 1994 1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union (ITU R) … Wikipedia
Mask (computing) — Signal masking redirects here. For other uses, see Masking (disambiguation). In computer science, a mask is data that is used for bitwise operations. Using a mask, multiple bits in a byte, nibble, word (etc.) can be set either on, off or inverted … Wikipedia
Critical band — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Psychophysiologically, beating and auditory roughness sensations can be linked to the inability… … Wikipedia
Critical bands — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Since Georg von Békésy’s studies (1960), the term also refers literally to the specific area on… … Wikipedia
Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… … Wikipedia
