A graphic equalizer also implements second-order filter functions in a more user-friendly manner but with somewhat less flexibility. This equipment is based on a bank of filters covering the audio spectrum in up to 31 frequency bands. Each second-order filter has a fixed center frequency and Q factor, but an adjustable level.
An idealized and extreme smiley face curve shown using a 29-band graphic equalizer. A smiley face curve or mid scoop [1] in audio signal processing is a target frequency response curve characterized by boosted low and high frequencies coupled with reduced midrange frequency power.

Graphic equalizers are fixed frequency equalizers; The center frequency of each band can not be adjusted. The bandwidth or Q of each band can either be 1/3, 2/3 or one octave, giving a 31-band, 15-band, or 10-band for a graphic equalizer that covers the audio frequency range. The narrower the band the more precisely the feedback frequency can ...
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
