Glossary 505
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.
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.
Environment The Environment is Logic’s brain: it graphically reflects the relationships
between hardware devices outside your computer and virtual devices within your
computer. Beyond basic input and output handling, the Environment can be used to
process MIDI data in real-time, and can even be used to create processing “machines”,
such as virtual rhythm generators and step sequencers or complex synthesizer editors.
Environment layer A place in the Environment, used to organize Objects and making
usage easier. Objects of the same type (Audio Objects, for example) are generally
placed on the same layer.
export To create a version of a file, such as a Logic song, in a different format that can
be distributed and used by other applications.
Freeze function The Freeze function performs individual offline bounce processes for
each “frozen” track, saving almost 100% of the CPU power used for software
instruments and effect plug-ins. All plug-ins of a track (including software instrument
plug-ins, if applicable, along with all related automation data) are rendered into a
“Freeze file”. You can use the Freeze function on individual Audio or Audio Instrument
tracks.
grab (an object) Positioning the mouse cursor over an object, then pressing and
holding the mouse button down.
hierarchical menu Structured menus where choosing an individual entry opens a
submenu.
importing The process of bringing files of various types into a Logic project or song.
Imported files can be created in another application, captured from another device, or
brought in from another Logic project.
Input Object Audio Object in the Environment’s Audio Layer. The Input Object
represents the physical inputs of your audio interface and helps managing audio from
your audio interface into Logic.
