The graphic EQ, as a whole, is made up of a bank of faders. The number of bands, of course, depends on the EQ in question.Įach band has a defined centre frequency and Q value with controllable gain via a fader. Graphic EQ does so with a set number of fixed frequency bands across the audible frequency spectrum. Now that we know what EQ is, let’s talk more specifically about graphic EQ.Īs the name would suggest, graphic EQ gives users a pretty descriptive visual representation of how it affects the audio. Whether graphic or otherwise, EQ is one of the most important tools for working with audio.įor more information on EQ in general, check out my article The Complete Guide To Audio Equalization & EQ Hardware/Software. Graphic EQs, as we’ll find out, have fixed bands (and often plenty of them)! The range in which an EQ filter will act up is typically referred to as a band. In the context of EQ, a filter (such as a “bell” or “peak” filter) can also be used to produce the previously mentioned boosting/cutting without affecting all frequencies beyond a certain point. It is used extensively in mixing, tone shaping, crossovers, feedback control and more.īoosting and cutting refer to the increasing and decreasing of the relative amplitude of defined frequency bands, respectively.Įlectronic filters are often described as processes that eliminate frequency content below, above or between two set frequency points.

EQ uses filters to either increase or decrease the amplitude of some frequency bands compared to other frequency bands.

In this article, we’ll discuss graphic EQ in great detail, focusing on how it works to apply equalization and the situations/applications it is best suited to serve. The name comes from the fact that the EQ settings of a graphic EQ unit typically look very obvious and “graphic”. What is graphic audio equalization? Graphic equalization is a style of EQ where predetermined bands centred around set frequencies with set Q factors that can be either boosted (amplified) or cut (attenuated).
