Glossary
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
almost twice as wide as it is high).
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-
digital converter, generating a stream of numbers.
On playback, a digital-to-analog converter generates an
analog signal based on these numbers. See also “Sam-
pling frequency” and “Analog audio.”
