Allows user to accentuate or de-emphasize selected frequencies within an audio sample. An example is the different 'tuning' for heart and lung sounds in electronic stethoscopes.
A multi-band variable equalizer using slide controls as the amplitude adjustable elements. Named for the positions of the sliders "graphically" illustrating the resulting frequency response of the equalizer. Only found on active (amplified) designs. Center frequency and bandwidth are fixed for each band.
A device with a group of volume faders, each assigned to adjust a portion of the audio frequency spectrum.
An active electronic device which allows the adjustment of narrow 'bands' of audio frequencies to correct for recording and listening room deficiencies. Graphic equalizers generally have sliding levers, known as faders, representing the different ranges of frequencies between 20 and 20,000 Hz.
An audio device with multiple frequency band boost and cut controls used to adjust the tonality of a audio signal.
a multi-frequency bandpass/reject filter that functions as a standalone unit, usually used to equalize specific loudspeaker systems
an electronic component with a bunch of level controls for limited frequency ranges
a piece of high-fidelity stereo equipment that controls (and sometimes displays) the nature of music's harmonic content
a powerful tool that characterizes and enhances audio
a system that is designed to allow you to control the amplitude of different audio-frequency ranges
Display that allows you to fine-tune your audio by increasing or decreasing the volume within specific frequency ranges.
Divides the sound input into smaller ranges of tones. This lets you adjust each range of sound to fit your preferences rather than just the high or low frequencies, as typical treble and bass buttons do.
A special type of equalizer that increases or decreases certain frequency ranges in response to the position of slider controls on its front panel. This type of equalizer creates a pattern representing a graph of the frequency-response changes.
A tone-control device whose amplification can be varied by octave, using slider controls whose positions provide an approximate visual graph of the frequency response.
is a device or computer algorithm that boost or cuts the volume of specific bands of frequencies in an audio signal.
Originally developed by Bell Laboratories, an equalizer is a device with which several narrow segments of the audio spectrum can be cut or boosted by individual faders. The device is so named because the fader positions provide a graphic reference of the EQ curve. These are commonly found on home-stereo equipment, due to their comparatively low cost.
a device which controls the tone of a signal by splitting it into a spectrum of frequency-bands, allowing each band to be boosted or cut separately. The word “graphic” refers to the fact that it is possible to see at a glance what particular “shape” is being used. E.g. a V-shape boosts the top end, while the opposite response adds mid-range warmth. Only tonal emphasis can be changed, it is not possible to improve the basic quality of the tone.
The graphic equalizer allows for custom-tailored sound reproduction.
A type of equalizer with sliding controls that create a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies; lowering sliders cuts (attenuates) the affected frequencies.
An device with several slides controlling the gain of audio signal present which is within one of several evenly spaced frequency bands (spaced according to octaves).
Sliding controls on a Graphic Equalizer create a pattern representing a graph of the frequency-response changes.
A series of adjustable frequency filters designed to
Expanded tone control, often 3, 5 or 7 sections. Gives you more control over the sound than a conventional bass/treble control.
a frequency-shaping device having multiple filter bands, each operating at a fixed frequency and bandwidth.
a device type that applies a series of bandpass filters to a sound, each of which works on a certain range of the spectrum. The frequencies that fall within the range, typically one-third octave, can be boosted or cut.
Form of equalizer (device used to adjust or change a signal's frequency response typically by changing its amplitude) using multiple previously set, fixed frequency bands to adjust the amplitude of the waveform at those specific frequencies.
A type of Equalizer (EQ) that provides control over a fixed set of frequencies. Each filter provides linear cut/boost control over a fixed frequency. The number of filters on graphic equalizers range from three (low, mid, high) to well over eleven. While graphic equalizers generally have more filters than Parametric Equalizer, they are less flexible, in that the individual filter frequencies are not adjustable.
Equalizer using small linear faders which permit manual control over a wide range of selectable frequencies.
An equalizer with control bands that are fixed in frequency but variable in level; the slider controls for the various bands provide a rough graphic representation of the selected frequency-response curve.
A circuit or system designed to allow you to control the amplitudes of different audio frequency ranges.
