430 Glossary
cueing Monitoring (hearing playback) while fast-forwarding or rewinding.
cutoff frequency Frequency at which the audio signal passing through a low or
highpass filter is attenuated by 3 dB.
cutting The act of reducing a level, or frequency, when using EQ or other filters. Also
used to describe physically dividing and removing sections of files, regions, and so on
(see boosting and attenuation).
DA converter or DAC Short for digital/analog converter; a device that changes an
analog signal into a digital signal.
data bytes These define the content of a MIDI message. The first data byte represents
the note, or controller number; and the second the velocity, or controller value.
DAW Acronym for Digital Audio Workstation. A computer used for recording, mixing,
and producing audio files.
dB Abbreviation for decibels, a unit of measurement that describes the relationships of
voltage levels, intensity, or power, particularly in audio systems.
DC offset An error that can result in direct current (DC) being layered over the audio
signal, resulting in a vertical shift in the waveform position shown in the Sample Editor.
decay An envelope parameter that determines the time it takes for a signal to fall from
the maximum attack level to the sustain level. See envelope.
deesser A signal processor that removes hissing or sibilance in audio signals.
default The preset parameter value.
delay Effect process that delays the incoming audio signal, resulting in subtle
chorusing effects through to endless repeats of the signal.
destructive Destructive audio processing means that the actual data of an audio file is
changed, as opposed to just editing peripheral or playback parameters.
DFS An abbreviation for Digital Full Scale. Sometimes expressed as 0 dB DFS. This is the
maximum theoretical level that a digital signal can reach before clipping and other
types of distortion may be introduced.
dialog A window containing a query or message. You must interact with it (by pressing
a button) before you can continue.
digital A description of data that is stored or transmitted as a sequence of ones and
zeros. Most commonly, refers to binary data represented by electronic or
electromagnetic signals. All files used in the Logic Express applications are digital. Also
see analog for comparison.
