An equaliser is a processor which is designed to deliberately alter the tonal quality of audio passing through it. It does this by using a number of filter circuits, which are capable of applying gain to audio signals within specific frequency ranges — both positive gain, referred to a 'boost', and negative gain, referred to as 'cut'.
Sep 28, 2023 · The width of a boost (or subtraction) is determined by Q Value. Higher Q's result in a narrow boost with shorter bandwidths, while lower Q's result in broader boosts with larger bandwidths.
This free downloadable EQ Cheat Sheet will help you understand the basic frequencies and settings for applying EQ to your mix! Feel free to bookmark this page or print your own copy to reference any time you’re working on a song! Below, there are also video examples and more in depth written instructions for using an EQ plugin!
Equalizers, or EQs, are powerful tools used to adjust the frequency response of an audio signal. They are used to fine-tune audio and achieve the desired sound quality. In this section, I will explain the different types of equalizers, the frequency spectrum, and the roles of EQ bands.

- Why Use A Parametric EQ?
A parametric EQ allows you to make a cut or a boost to the frequency spectrum. The frequency response curve created by a parametric EQ is referred to as a ‘bell’ curve, so-called due to its shape. You may also hear it referred to as a ‘peak’ curve. These bell shaped cuts and boosts can be made to your desired gain amount. For example, here you can ...
To achieve these different kinds of equalization, you must control three separate parameters. Those parameters are: gain, centre frequency and bandwidth: Gain: The gain parameter on a parametric equalizerallows you to control the amount of boost or cut that you are applying. Centre Frequency: The centre frequency refers to the frequency which resid...
A parametric EQ which allows you to control all three of these parameters is known as ‘fully-parametric’. But there are some equalizers which create the same kind of bell shaped cut or boost, but offer you less control than that of a fully-parametric EQ. An EQ which allows you to control only the gain and the centre frequency, but not the Q setting...
Parametric equalizers offer an unparalleled level of control over the kind of equalization you create. By allowing you to take control over the equalizer’s gain, centre frequency and bandwidth parameters, you are able to make precise EQ alterations to suit the needs of your track. You are able to make changes to large portions of the frequency spec...
Feb 2, 2024 · Equalizers must be used with a real-time audio analyzer to correct for anomalies in the frequency response of an audio system. Everything from your smartphone and smart speaker on your bedside table to movie theaters and concert venues uses equalizers to improve an audio system’s frequency response.

What is a parametric equalizer?
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).
