Glossary
A visual representation of individual audio, video, or MIDI files in Adobe Audition's
Clip
Multitrack View.
In digital audio, distortion that occurs when the amplitude of a signal exceeds
Clipping
the maximum level for the current bit resolution (for example, 256 in 8-bit audio).
Visually, clipped audio produces broad flat areas at the top of a waveform. If you
experience clipping, lower the recording input or the source output levels.
(Compressor/Decompressor) An abbreviation often used to describe multi-
CODEC
media compression schemes used by ACM, MPEG, QuickTime, AVI, and the combined
A-D-D-A modules on some sound cards.
Reduces dynamic range by lowering amplitude when an audio signal rises
Compressor
above a specified threshold. For example, compressors can be used to eliminate variations
in the level of an electric bass, providing an even, solid bass line. Compressors can also
compensate for variations in level produced by a vocalist who moves frequently or has an
erratic volume.
A fade from one audio track to another.
Crossfade
Undesired leakage of audio from one track to another, a common problem with
Crosstalk
analog tape. Crosstalk is impossible in Adobe Audition because each track is stored as a
separate digital audio file.
A list of time locations defined in an audio file. A cue can be either a point that
Cue List
specifies a time position or a range that specifies a selection. In Adobe Audition, you can
define and save an unlimited number of cues for later recall or for assembly in the Play List
window. (See "Play List" on page 285.)
D
(Digital-to-Analog Converter) The hardware responsible for converting a digital
DAC
audio or video signal into an analog signal that you can play through amplifiers and
speakers.
(Digital Audio Tape) A standard two-track digital audio tape format. DAT tapes are
DAT
sampled at 16 and 24 bits, and 32,000, 44,100, and 48,000 samples per second. (The latter
is often described as DAT quality).
