156 Glossary
reverb Reverb(eration) is the sound of a space. More specifically, the reflections of
soundwaves within a space. As an example, a handclap in a cathedral will reverberate
for a long time as sound waves bounce off the stone surfaces within a very large space.
A handclap in a broom closet will hardly reverberate at all. This is because the time it
takes for the soundwaves to reach the walls and bounce back to your ears is very short,
so the “reverb”’ effect will probably not even be heard.
routing Generally refers to the way audio is sent through processing units. Also often
used to describe specific input and output assignments.
sample A digital recording of a sound at a particular instant in time.
Sample Editor Logic’s Sample Editor allows stereo or mono audio files to be
destructively cut, reversed, shortened, changed in gain and processed in a number of
other ways. It allows editing of individual samples within an audio file consisting of
thousands or millions of samples. The Sample Editor also provides access to a number
of special sample processing tools, collectively known as the Digital Factory.
sampler Device used for sampling. In Logic, this generally refers to the EXSP24
software-based sampler.
sample rate When an analog audio signal is converted to a digital signal, this term
refers to the number of times per second the audio file is sampled. Logic can record
and edit audio at sample rates ranging from 44.1 kHz (44,100 times per second) up to
192 kHz (192,000 times per second).
sampling The process of converting analog audio into digital information. The sample
rate of an audio stream specifies the number of samples that are captured per second
(see sample rate). Higher sample rates yield higher quality audio.
saturation A term most commonly associated with a slight tape distortion or the
characteristics of tube amplifiers. It basically describes a very high gain level that causes
a slight distortion of the incoming signal, resulting in a warm, rounded sound.
scroll bar and scroll box Gray beam at the edge of a window. A movable box inside
the beam is used to select the displayed song section in the window.
self-oscillation Self-oscillation is a typical characteristic of analog filter circuits. It
occurs when the filter, at high resonance values, feeds back into itself and begins to
oscillate at its natural frequency.
semitone Smallest interval between two pitches in the standard diatonic scale, equal
to a half tone. Correspondingly a semitone is also called half step or half tone.
