Glossary 147
digital A description of data that is stored or transmitted as a sequence of ones and
zeros. Most commonly, refers to binary data represented using electronic or
electromagnetic signals. All files used in Logic are digital. Also see analog for
comparison.
disclosure triangle A small triangle you click to show or hide details in the user
interface.
distortion The effect produced when the limit of what can be accurately reproduced
in a digital signal is surpassed, resulting in a sharp, crackling sound.
drag & drop Grabbing objects with the mouse, moving them, and releasing the mouse
button.
driver Drivers are software programs that enable various pieces of hardware and
software to be recognized by other programs in a computer, and also to have the
appropriate data routed to them in a format they can understand. In Logic, you can use
the Preferences > Audio > Drivers panel to select and configure your audio hardware
drivers. If you do not have the proper driver installed, your computer may not
recognize or work properly with a given piece of hardware.
DSP (digital signal processing) In Logic, the mathematical processing of digital
information to modify a signal. An example is the Insert slot of channel strips, which
assigns DSP effects such as dynamic compression and delay to a channel’s signal.
dynamics Refers to changes in volume or other aspects of a piece of music over time.
dynamic range The dynamic range of a sound system is the difference in level
between the highest signal peak that can be reproduced by the system (or device in
the system) and the amplitude of the highest spectral component of the noise floor.
The dynamic range is the difference between the loudest and softest signals that the
system can reproduce. It is measured in decibels (dB). See decibels.
editor Window for editing MIDI or audio data. Logic offers the Hyper, Matrix, and Score
editors for MIDI event data, and the Sample Editor for audio data.
Editor view Almost all Logic plug-ins (and Audio Units) offer a graphical view of effect
and instrument parameters. The Editor view is used by default, but can be accessed via
the Editor pull-down menu at the top of each plug-in window, should the Controls
view be visible.
effect A type of software algorithm that lets you alter the sound of a track in a variety
of ways. Logic includes a set of EQ, dynamics, time-based, modulation, and distortion
effects in Logic’s native and Audio Unit plug-in formats.
