A jukebox is a partially automated music-playing device, usually a coin-operated machine, that plays a user-selected song from a self-contained media library. Traditional jukeboxes contain records, compact discs, or digital files, and allow users to select songs through mechanical buttons, a touch screen, or keypads. They were most commonly found in diners, bars, and entertainment venues throughout the 20th century.

A driver is commonly installed in an enclosure (often a wooden cabinet) to prevent the sound waves coming off the back of the driver diaphragm from canceling out the sound waves being generated from the front of the subwoofer. thumb|A typical Hi-Fi subwoofer (r.), with the subwoofer loudspeaker built into a cabinet.

form of audio post-production

musical instrument that produces its sounds using electronics

recording of sound and playing it back

audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds thus reducing or compressing an audio signal's dynamic range

representation of sound, typically as an electrical voltage

family of connector typically used for analog signals

digital audio workstation

chemical compound

device for acoustic measurements

process by which multiple sounds are combined into one or more channels

method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first

In electronics, crosstalk (XT) is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit or channel to another.

thumb|Over-ear headphones sold by [[Audio-Technica, an audiophile-oriented brand.]] An audiophile (from + ) is a person who is enthusiastic about high-fidelity sound reproduction. An audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics.

Backmasking is a recording technique in which a message is recorded backward onto a track that is meant to be played forward. It is a deliberate process, whereas a message found through phonetic reversal may be unintentional.

acoustical component; empty box intended for one or several loudspeakers; does not include the loudspeakers themselves

thumb|A DJ scratching a record Scratching, sometimes referred to as scrubbing, is a DJ and turntablist technique of moving a vinyl record back and forth on a turntable to produce percussive or rhythmic sounds. A crossfader on a DJ mixer may be used to fade between two records simultaneously.

electronic component which reduces a signal's amplitude

A remaster is a change in the sound or image quality of previously created forms of media, whether audiophonic, cinematic, or videographic. The resulting product is said to be remastered. The terms digital remastering and digitally remastered are also used.
