Analog audio

An electrical signal that directly represents sound. Com-
pare this to digital audio which can be an electrical sig-
nal, but is an indirect representation of sound. See also
“Digital audio.”

Aspect ratio

The width of a TV screen relative to its height. Conven-
tional TVs are 4:3 (in other words, the screen is almost
square); widescreen models are 16:9 (the screen is

Digital audio

An indirect representation of sound by numbers. During
recording, the sound is measured at discrete intervals
(44,100 times a second for CD audio) by an analog-to-

On playback, a digital-to-analog converter generates an
analog signal based on these numbers. See also “Sam-
pling frequency” and “Analog audio.”
