- At its most basic definition, an equalizer manipulates frequencies. The technology first took off as a piece of analog electronics that was initially used in recording studios before making its way into the home. Whether analog or digital, an EQ is used to adjust different elements of sound to achieve an end result that appeals to the listener.

Let's start with one of the most important terms when dealing with EQ settings: Frequency. Frequency represents the number of cycles (or sonic vibrations) per second, and is measured in Hertz (Hz). Thus, a frequency of 1Hz is the equivalent of one vibration per second, and a frequency of 1kHz is equal to one thousand vibrations per second. The rang...
Building on the above, an EQ is a tool to adjust the gain of various frequency ranges in the complete frequency range of a given output device. Before we get to consumer applications of EQ, we must establish a few more technical terms, even if you're less likely to encounter full-scale versions of them. Aparametric EQ is a common studio tool that's...
So, now that you understand how EQ works, what are your plans for it? Go crazy and dial up the bass to 11? Probably not. It's important to remember that, in the recording studio, an EQ is first and foremost a tool for dealing with problematic frequencies that stand out in a recording. Secondly, it is a creative tool—there might not be a problem to ...

An equalizer is a unit that equalizes or compensates for different tonal side effects and places them in synchronization. In this way, the equalizer changes the quality of the audio tone that passes through it.
Mar 25, 2024 · The decibel (dB) is the unit of measurement used to express volume level or loudness. When you move a slider up or down on an EQ, you are increasing or decreasing the loudness of that...
- Graphic EQ. A graphic EQ works by separating individual frequencies into banks of sliders which you can add or remove as needed. The more frequencies contained on a graphic EQ the more accurate the controls are.
- Parametric EQ. A Parametric EQ is the most common type of EQ you will come across when mixing in the box. Your DAW will usually come with an EQ plugin as standard and may also utilize an analyzer which displays the frequencies present in the track.
- Shelving EQ. A shelving EQ is actually quite similar to a HPF/LPF. The term ‘shelf’ comes from the way in which the EQ parameters look. Whereas a HPF/LPF will have a steep curve, with a sudden drop off in frequencies, a shelving EQ will have a wide Q and a smooth curve which slopes to form a shelf-like shape.
- Linear Phase EQ. A Linear Phase EQ works very similarly to your Parametric EQ. When adding or removing frequencies in your Parametric EQ plugins a ‘smearing’ effect is created, where any frequency you are altering comes slightly out of phase with the rest of the frequencies in the signal.
Apr 28, 2021 · An audio equalizer works in the exact same way but is much more precise and versatile. It can boost or reduce any frequency or range of frequencies across the human hearing range, from 20Hz – 20kHz. To see how it works let’s examine a typical digital EQ plug-in that you would find in any DAW.
Feb 18, 2024 · First, we will explore how to use an equalizer to sculpt the sound of individual instruments within a mix. We will provide hands-on exercises to demonstrate how to identify and address frequency clashes and how to use EQ to bring out the best in each instrument.
