A good example of time-controlled noise gating is the well-known "gated reverb" effect heard on the drums on the Phil Collins hit single "In the Air Tonight", created by engineer-producer Hugh Padgham, in which the powerful reverberation added to the drums is cut off by the noise gate after a few milliseconds, rather than being allowed to decay ...
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.
Definition. One definition of signal-to-noise ratio is the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): where P is average power. Both signal and noise power must be measured at the same or equivalent points in a system, and within the same system bandwidth.
For example, in live sound reinforcement, a noise gate is often employed to mute or attenuate the microphone signal when the sound level falls below a certain threshold. This helps minimize the pickup of ambient noise and unwanted signals. 3. Radar systems: Signal gating plays a crucial role in radar systems, particularly in pulse-Doppler radar ...
Gated reverb on a snare drum, produced by a plugin. Gated reverb or gated ambience is an audio processing technique that combines strong reverb and a noise gate that cuts the tail of the reverb. The effect is typically applied to recordings of drums (or live sound reinforcement of drums in a PA system) to make the hits sound powerful and ...
Gaussian noise. In signal processing theory, Gaussian noise, named after Carl Friedrich Gauss, is a kind of signal noise that has a probability density function (pdf) equal to that of the normal distribution (which is also known as the Gaussian distribution). [1][2] In other words, the values that the noise can take are Gaussian-distributed.
In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.
Noise (signal processing) In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications that a signal may suffer during capture, storage, transmission, processing, or conversion. [1] Sometimes the word is also used to mean signals that are random (unpredictable) and carry no useful information; even if they ...
