Becoming more aware of the impacts and differences of EQ and IQ often makes us believe that EQ is sufficiently more important than ones general intelligence because being true to oneself is the easiest way of living life to the fullest.

Graphic Equalizers
Graphic Equalizers

A graphic equalizer is a high-fidelity audio control that allows the user to see graphically and control individually a number of different frequency bands in a stereophonic system. A typical graphic equalizer consists of several audio filter/amplifiers, each centered at a specific frequency in the audio range.

Parametric EQ:
Parametric EQ:

Parametric EQ. The parametric EQ is a mainstay of recording and live sound because it offers continuous control over every parameter. A parametric equalizer offers continuous control over the audio signal’s frequency content, which is divided into several bands of frequencies (most commonly three to seven bands).

Semiparametric Equalizer:
Semiparametric Equalizer:

Sometimes called pseudo or quasi-parametric EQ, a semi-paramteric EQ is a parametric equalizer that has one or more features missing.This term is sometimes used to describe a single band of equalization, where it generally means a parametric EQ that does not have a Q control (the Q is fixed).

Shelving EQ
Shelving EQ

In a shelving EQ, a band of frequencies is boosted or cut either in the high frequency end of the spectrum as shown, or in the low frequency end. 'Shelving' is not a term that is ever applied to a mid-range boost or cut. So in a shelving EQ, all frequencies above or below a certain frequency are boosted or cut by the same amount.
