GLOSSARY
A
.AUD
A sound file format developed by ESS Tech-
nology Inc. This format allows you to record and
play back sound files at 16-bits per sample, set a
higher sampling rate and select a level of compres-
sion.
ADC
Analog-to-Digital Converter. A chip that
takes analog sound information and transforms it
into digital sound data that can be stored in the hard
drive of your PC.
ADI 1848 Codec
An implementation of the
ADPCM compression standard. The 1848 Codec is
an electronic circuit that converts voice or video into
digital code (and vice versa) using techniques such
as pulse code modulation and delta modulation.
ADPCM
Adaptive Digital Pulse Code Modulation.
A data compression routine that reduces the disk
space used when sampling sound. Sampled sounds
use a lot of disk space. For example, one minute of
recorded voice annotation requires 660K of disk
space. When using ADPCM the disk space is half the
amount or 330K. ADPCM allows for 2:1, 3:1 and 4:1
compression ratios when sampling sound.
audio
A range of frequencies within human hear-
ing. Audio is processed in a computer by converting
the analog signal into a digital code using various
techniques, such as PCM.
AUTOEXEC.BAT
A special DOS batch file that al-
lows you to tailor the DOS operating system to your
needs. It contains instructions and commands to set
parameters to execute programs every time the sys-
tem boots up, and must be installed in the root
directory of your boot drive.
