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.
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. [1][2] In many situations, a sound reinforcement system is also ...
An audio engineer with audio console, at a recording session at the Danish Broadcasting Corporation. An audio engineer (also known as a sound engineer or recording engineer) [1] [2] helps to produce a recording or a live performance, balancing and adjusting sound sources using equalization, dynamics processing and audio effects, mixing, reproduction, and reinforcement of sound.
Pitch correction. 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). Pitch correction devices do this without affecting other aspects of its sound.
An audio engineer adjusts a mixer while doing live sound for a band. A mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds.
The volume (gain) control is used to adjust the amount of amplification applied to the electric signal and thus, indirectly, controls the sound volume. The devices vary in size from small boxes (with an earpiece attached) worn around the neck or hung off of a belt - down to - a tiny encapsulated device that fits inside the ear canal.
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. The term " out of tune " refers to a pitch/tone that is either too high (sharp) or too low (flat) in relation to a given reference pitch.
Radio receiver. A portable battery-powered AM/FM broadcast receiver, used to listen to audio broadcast by local radio stations. A modern communications receiver, used in two-way radio communication stations to talk with remote locations by shortwave radio. Girl listening to vacuum tube console radio in the 1940s.
