In addition to controllling bass and treble, it has the ability to raise and lower the level of a given frequency. A parametric equalizer is useful in pulling certain frequencies above the noise in a tape.
An equalizer with one or more "bands"; each having a control for frequency, bandwidth, and level. With such an equalizer, one can zero in on a specific frequency or range of frequencies and then cut or boost as desired. Some parametric equalizers on mixers and some outboard gear only provides control over the frequency and level, but not the bandwidth. These are called semi-parametric equalizers. see graphic equalizer
A type of audio equalizer having several "parameters" for control of various filters that can be applied to audio signals. Parametric equalizers are most widely used in situations where very fine control over the audio signal is desired, and provide control over gain, Q (Quality factor, a measure of a resonant system), and frequency.
a tone control where equalizer digital the level of boost or cut,
An equalizer consisting of several filters each of which can be adjusted in each of three parameters: frequency, bandwidth or Q, and amplitude, allowing it to closely match the properties of resonances which are to be attenuated. See:Resonance, Graphic Equalizer.
Sony's latest ATRAC3/MP3 CD Walkman features a Parametric Equalizer with three Presets and a Custom mode that lets you design your own sound. In Custom mode, three frequency ranges can be adjusted to your audio preferences. For instance, you could boost the bass (low), soften the vocals (mid) and enhance the violin sounds (high). It's music the way you like it. The Parametric Equalizer lets you design your own sound with 3 Presets (Soft, Active, Heavy) and 1 Custom mode. Choose how you want your music to sound: Soft for vocals, Active for lively sounds, and Heavy for powerful sounds. In Custom mode, adjust the 3 frequency ranges (Low, Mid and High) to your liking
a circuit designed for frequency-selective attenuation or boosting of a signal's amplitude, with independent controls for gain, center frequency and bandwidth (including continuously adjustable Q). A quasi-parametric EQ may provide full frequency and gain adjustment, but only two or three Q settings. Sweepable EQs have an adjustable (sweepable) center frequency, but operate on a fixed bandwidth.
A type of Equalizer (EQ) that provides control over each filter's frequency and the amount of cut or boost of each filter. Typically, parametric equalizer's provide three to four filters that work in parallel, each one filtering a different frequency of the spectrum (i.e. low, mid, high). While parametric equalizers generally have fewer filters than a Graphic Equalizer, they are more flexible and provide finer control, due to the adjustability of the filtered frequencies.
An equalizer with separate controls for frequency, bandwidth and cut/boost.
