The Equalizer (EQ) effect is an audio processing tool used to alter the balance of frequencies within a sound signal. It functions essentially as a frequency-specific volume knob, allowing you to make certain pitches louder or quieter without affecting the rest of the sound.

Every sound—whether it is a human voice, a guitar, or a car engine—is made up of a unique mix of frequencies ranging from low bass to high treble. Human hearing typically covers a spectrum from 20 Hz to 20,000 Hz (20 kHz).
An equalizer breaks this spectrum down into target areas so you can manipulate them independently:
Boost: Increasing the volume (gain) of a specific frequency range to make it more prominent.
Cut (Attenuate): Decreasing the volume of a frequency range to quiet down or eliminate unwanted sounds. Common Applications
