Introduction to Equalization

intro-eq iconEQ is an essential tool in a mixers' bag of tricks.   EQ was developed as a way to "equalize" differing sources to sound similar.  It can alter the frequency characteristics of a recorded sound.   It can enhance recordings by boosting, reducing or even removing certain frequencies.   The simplest and most common EQ are what used to be called the "tone control" or the "treble" and "bass" knobs common on car radios or home receivers.  There can also be additional controls such as a "presence" switch or a "bass boost" switch.
