Glossary
Analog audio
An electrical signal that directly represents sound.
Compare this to digital audio which can be an electrical
signal, but is an indirect representation of sound. See
also Digital audio.
Aspect ratio
The width of a TV screen relative to its height.
Conventional 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).
Chapter
Just as a book is split up into several chapters, a title on
the HDD/a DVD disc is usually divided into chapters. See
also Title.
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
Sampling frequency and Analog audio.
