The Complete Lesson on Getting Started With EQ

Definitions/Explanations:
Equalization is the increase or decrease of signal strength for a portion of (a band of) audio frequencies.  The audio we record (the sound made by instruments or voices) is complex.  By this we mean that it is composed of energy at different audio frequencies.  If we take a bass control (a simple equalizer) and turn the knob clockwise, we will get an increase in strength of the signal (or the signal component) that has lower frequencies (usually any component below about 500 Hz).  Thus equalization effects the tone because it changes the level relationship of the fundamental and harmonic frequencies.
