Parametric Equalizer is an electronic multi-band variable equalizer device used in sound recording and live sound production. This devices allow audio engineers to control the parameters of the internal band-pass filter sections. The amplitude of each band can be controlled, and center frequency can be shifted, widened, and narrowed.
Audio Filters: Designing an audio equalizer – Part 7
https://www.engineersgarage.com/audio-filters-designing-an-audio-equalizer-7-8/
For this project, we’ll design a three-band, graphic equalizer circuit using audio filters. So, it will have low, high, and band-pass filter circuits to separate the low, high, and mid-range frequencies of the audio signal. The circuits will be active filters using an operational amplifier (op-amps).
Audio Graphic Equalizer Circuit

Below we present an Audio Graphic Equalizer circuit, based on Philips Semiconductors Application Note 142 (published on October 1984). The circuit itself has great performance and uses a top performance operational amplifier; the NE5532.. The graphic-equalizer consists of an input buffer (IC1 -a), a variable-boost/ cut active filter (lC2-a), and an …
