ABSTRACT
Spectral balance refers to an audio signal’s frequency content and the relative power of each frequency or frequency band across the audible range of frequencies, from 20 to 20,000 Hz. An audio signal with a fl at spectral balance would represent all frequencies at the same relative amplitude. Often audio engineers describe the spectral balance of sound through equalization parameters, as the equalizer is the primary tool for altering the spectral balance of sound. An engineer can boost or cut specifi c frequencies or ranges of frequencies with an equalizer to bring out lowlevel details or to compensate for unwanted resonances.
