Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer .
RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times (by decreasing the mean width of each groove), to improve sound quality, and to reduce the groove damage that would ...
Equalization – Equalization is a broad term for any device that can alter parts of a signal frequency response. Some EQs use a grid of faders or knobs which can be arranged to shape each frequency, whereas others use bands that can target and subsequently boost or cut selectable series of frequencies.
The purpose of replay equalization is to compensate for high-frequency losses during recording, [28] which, in case of ferric cassettes, usually start at around 1–1.5 kHz. The choice of time constant is a somewhat arbitrary decision, seeking the best combination of conflicting parameters — extended treble response, maximum output, minimum ...

An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.
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.
