U
unity gain An amplification level that precisely corresponds to the input signal level, without amplifying or lowering
it. (Note that audio hardware operates at two line levels: –10 dBV for consumer equipment, and +4 dBu for profes-
sional. If these two hardware types are connected, unity gain will result in a lowered input for consumer equipment,
and a raised input for professional.)
V
VST Virtual Studio Technology, a plug-in format compatible with a wide variety of audio software. VST plug-ins
provide audio effects such as compression and reverb; VSTi plug-ins provide virtual instruments such as samplers
and synthesizers.
W
waveform A term that describes the visual representation of an audio signal, displayed as amplitude across time in
Adobe Audition. (In acoustics, waveform refers to a sound wave of a specific frequency.)
wet Describes an audio signal that includes signal processing such as reverb; the opposite of dry.
white noise White noise has a spectral frequency of 1, so equal proportions of all frequencies are present. Because
more individual frequencies exist in the upper ranges of human hearing, white noise sounds very hissy. Adobe
Audition generates white noise by choosing random values for each sample.
Z
zero crossing A point in time where a waveform crosses the zero amplitude line. To make edits sound smoother,
place them at zero-crossing points, thus avoiding abrupt changes in amplitude that cause pops and clicks.
