Smiley Face Curve (Paperback)

High Quality Content by WIKIPEDIA articles! A smiley face curve in audio signal processing, is a target frequency response curve characterized by boosted low and high frequencies coupled with reduced midrange frequency power. This curve is often attained by users employing a graphic equalizer which shows a graphic representation of a "smile" using its frequency band faders to describe a curve that sweeps upward at the left and right sides. Smiley face curves have had a popular appeal with some car audio enthusiasts, disc jockeys, electric bass guitar players, home stereo owners and live sound reinforcement system operators. Though the graphic equalizer was intended to tailor a system's response to match existing venue and performance conditions, the smiley face curve is often applied before the user has heard the system's frequency response.
