Application
Equalizers can correct problems posed by a room's acoustics, as an auditorium will generally have
an uneven frequency response especially due to standing waves and acoustic dampening. The
frequency response of a room may be analyzed using a spectrum analyzer and a pink noise
generator for instance. Then a graphic equalizer can be easily adjusted to compensate for the
room's acoustics. Such compensation can also be applied to tweak the sound quality of a recording
studio in addition to its use in live sound reinforcement systems.
