Dry/Wet
A sound devoid of reverberation or signal processing.
A sound with reverberation or signal processing.
Equalizer
A signal-processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system.
Filter
A device that removes unwanted frequencies or noise from a signal.
High Pass Filter / Lo Cut Filter
A filter that attenuates frequencies below a selected frequency and allows those above that point to pass.
Time Compress/ Expand
Shortening the time (length) of
material without changing its pitch.
Increasing the time (length) of material without changing its pitch.
Pitch Shift
A signal processor that varies the pitch of a signal. The basic parameter for pitch shifting is transposition.
Flanging
Combining a direct signal and the same sig- nal slightly delayed and continuously varying their time relationships, using a time delay.
Chorus
Recirculating the doubling effect to make one sound source sound like several. See also doubling.
Delay
The time interval between a sound or signal and each of its repeats.
Echo
Sound reflections delayed by 35 ms or more that are perceived as discrete repetitions of the direct sound.
Compression
(1) Reducing a signal’s output level in relation to its input level to reduce dynamic range. (2) The drawing together of vibrating mol- ecules, producing a high-pressure area. See also rarefaction.
Limiter
A compressor with an output level that does not exceed a preset ceiling regardless of the input level.
De-esser
A compressor that reduces sibilance.
