Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano).
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. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
For example, the RIAA pre-emphasis in the popular Neumann SAB 74B equalizer applies a second-order roll off at 49.9 kHz, implemented by a Butterworth (maximally flat) active filter, plus an additional pole at 482 kHz. [2] This cannot be compensated for by a simple zero even if it were necessary, and in any case, other amplifiers will differ.
An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel. [1] It is frequently used with coherent modulations such as phase-shift keying, mitigating the effects of multipath propagation and Doppler spreading. Adaptive equalizers are a subclass of adaptive filters.

Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz.
Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.
It was the replacement for the DC17. Has a powered cam to adjust the height of the brushbar ("Dyson Airmuscle") controlled from a set of buttons by the main power switch above the cyclone assembly, a pneumatic actuator to keep the cleaning head on the floor, and a high-torque clutch to give extra power to the brushbar.
