Equalization (or EQ) refers to the adjustment of audio frequencies produced by vocals, which can either be cut or boosted to reduce or increase the presence of a specific frequency or frequency band. This is usually done to improve the audio aesthetics of vocal sounds.

EQ may also be used to eliminate or reduce unwanted sounds and transients, and altering EQ is a good way to adjust the timbre of the vocals by modifying the substance of its frequencies. This can furthermore assist in fitting the vocal tracks within the sonic spectrum and overall context of the mix.


Depending on the objective of the project, different EQ units will deliver different tones and character to vocals tracks.
