994 Glossary
routing Generally refers to the way audio is sent through processing units. Also often
used to describe specific input and output assignments.
rubber band selection Technique for selecting consecutive regions, objects, or events
by click-holding and dragging the mouse cursor around the desired items. A rubber
band selection envelope (an outline) will expand from the starting position of the
mouse cursor. All objects touched or enclosed by the rubber band selection envelope
will be selected.
sample A digital recording of a sound at a particular instant in time.
Sample Editor The Logic Pro Sample Editor allows 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 Pro, this generally refers to the EXS24 mkII
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 Pro 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).
sample rate converter Device or algorithm that translates one sample rate to another.
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.
scale A group of related musical notes (or pitches) that forms the basis of the melody
and harmony in a piece of music. The most common scales are the major scale and
minor scale.
scan code Each key on a computer keyboard has a scan code rather than an ASCII
symbol associated with it. As an example: The plus and minus keys on the numeric
keypad and the corresponding keys above the keyboard have a different scan code,
but use the same ASCII symbol.
scene marker Logic Pro can automatically extract information from (abrupt) transitions
in QuickTime movie files, and create a marker, making the process of scoring to film
much faster and easier. Such transitions in video generally indicate a scene change.
