Glossary 145
CD Audio Short for Compact Disc—Audio; current standard for stereo music
CDs: 44.1 kHz sampling rate and 16 bit depth.
cent A tuning subdivision of a semitone. There are one hundred cents in a semitone.
Many of Logic’s software instruments contain a Fine parameter that allows sounds to
be tuned in cent steps.
channel strip A channel strip is a virtual representation of a channel strip on a mixing
console. Each channel strip contains a number of similar controls, such as a Mute
button, Volume fader, Pan/Balance knob, Output selector and Bus and/or Insert slots.
Channel Strip setting Logic allows the routing of a channel strip, including all inserted
effects or instruments (plus their settings) to be saved and recalled. This simplifies the
task of recreating complex serial effect routings between channels or songs.
checkbox A small box. You click a checkbox to select or deselect an option.
chorus effect Effect achieved by layering two identical sounds with a delay and
slightly modulating the delay time of one or both of the sounds. This makes the audio
signal routed through the effect sound thicker and richer, giving the illusion of multiple
voices.
click Metronome, or metronome sound.
Clipboard The Clipboard is an invisible area of memory, into which you cut or copy
selected objects, using the Edit menu. From there, you can paste these objects to
different positions. Logic’s Clipboard spans all songs, allowing it to be used to exchange
objects between songs.
clipping (in digital recording) Feeding too much signal through a channel strip,
thereby exceeding the limit of what can be accurately reproduced results in a distorted
sound known as clipping. Logic’s Audio Objects feature a clip detector, which indicates
signal level peaks above 0 dB.
comb filter effect A short delay of feedback that emphasizes specific harmonics in a
signal is generally termed a comb filter. The name is derived from the appearance of a
frequency spectrum graphic, which resembles the teeth of a comb.
compressor An effect that restricts the dynamic range of an audio signal.
controller MIDI data type. As examples; sliders, pedals, or standard parameters like
volume and panning. The type of command is encoded in the first data byte, the value
in the second data byte.
