George Y. Massenburg (born Baltimore, Maryland c. 1947) is a Grammy award-winning recording engineer and inventor.Working principally in Baltimore, Los Angeles, Nashville, and Macon, Georgia, Massenburg is widely known for submitting a paper to the Audio Engineering Society in 1972 regarding the parametric equalizer.
The original stand-alone unit was called the ITI ME-230 (Mastering Equalizer 230) and was the first commercially available parametric EQ. [1] [4] Massenburg and Macneal type-set and printed a paper entitled “Parametric Equalization” in 1972 and Massenburg submitted it to the Audio Engineering Society in Los Angeles.
Parametric equalizers are capable of making much more precise adjustments to the sound than other equalizers and are commonly used in sound recording and live sound reinforcement. A variant of the parametric equalizer is the semi-parametric equalizer, a sweepable filter. It allows users to control the gain and frequency but uses a pre-set ...

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 ...
In some applications, such as in the design of graphic equalizers or CD players, the filters are designed according to a set of objective criteria such as passband, passband attenuation, stopband, and stopband attenuation, where the passbands are the frequency ranges for which audio is attenuated less than a specified maximum, and the stopbands are the frequency ranges for which the audio must ...
Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in ...
Smiley face curves have been popular with some car audio enthusiasts, disc jockeys, electric bass players, home stereo owners and sound reinforcement operators. [ 2 ] [ 3 ] Though the graphic equalizer was intended to tailor a system's response to compensate for venue and performance conditions, the smiley face curve is sometimes applied as a ...
