This post focuses on the basics of equalization.
Equalization is something that most people are probably pretty familiar with on a basic level, having some EQ capacity in their car stereos and portable players. Essentially, EQ is cutting or boosting of frequencies or frequency ranges.
There are fundamentally two kinds of equalization: graphic and parametric. Graphic EQ usually has set frequency points with sliders to boost or cut at those points. Parametric usually has a set of moveable frequency ‘centers’ with a width control, combined with a cut and boost knob.
