This blog post will teach you how to correctly manipulate an EQ on an audio device so that you may achieve the sound you want without losing the original acoustic image and fidelity.
First of all, what IS an equalizer?
An equalizer is an electronic circuit that allows you to selectively amplify an audio signal based on various frequency bands. This is typically accomplished using independent volume controls for each frequenmcy band. The simplest equalizer (or EQ, as it is also known) would be a "bass" and "treble" knob on a basic stereo system. Turning up the Bass will make the lower frequencies louder, while turning up the treble will make the higher ones louder.
