Dynamic range compression. This article is about a process that intentionally reduces the dynamic range of audio signals. For similar reductions caused by circuit imperfections, see Gain compression. For processes that reduce the size of digital audio files, see Audio compression (data). A rack of audio compressors in a recording studio.
Red (Brownian) Purple. Grey. v. t. e. In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process ). Different colors of noise have significantly different properties. For example, as audio signals they will ...
Mel-frequency cepstrum. In sound processing, the mel-frequency cepstrum ( MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients ( MFCCs) are coefficients that collectively make up an MFC. [ 1]
GuitarFreaks (ギターフリークス, Gitāfurīkusu) is a music video game series produced by Konami. It is a rhythm game where the player uses a controller to simulate the playing of an electric guitar. The game consists of music predominantly from the rock music, rock and roll and J-pop genres. It is considered one of the most influential ...
Shepard tone. A spectrum view of ascending Shepard tones on a linear frequency scale. A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale.
The sawtooth wave is the form of the vertical and horizontal deflection signals used to generate a raster on CRT -based television or monitor screens. Oscilloscopes also use a sawtooth wave for their horizontal deflection, though they typically use electrostatic deflection. On the wave's "ramp", the magnetic field produced by the deflection ...
HP’s latest gaming mic is the Las Vegas casino of microphones. If you’ve ever browsed Razer’s selection of gaming peripherals and thought, “You guys need to step up your RGB game,” HP ...
The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing. The theorem states that the sample rate must be at least twice the bandwidth of the signal to avoid aliasing.
