Apple Logic Pro 9 - Manual (Page 1332)

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.
sampler Device used for sampling. In Logic Pro, this generally refers to the EXS24 mkII
software-based sampler.
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.
Score Editor Logic Pro editor that deals with standard musical notation. MIDI note events
are represented as quavers, crotchets, minims, and so on. The Score Editor allows you to
adjust and edit the layout of the score, and print it.
score set A collection of various staff styles, staffs, and other elements shown in the Score
Editor can be saved as a score set. This facility allows you to quickly switch between (and
edit and print) different portions of the score, such as a brass section, in isolation to the
entire score. It also simplifies experimentation with different layouts.
screenset A layout of various windows, inclusive of all display parameters (zoom, position,
size of each window, and so on) is called a screenset. You can swap between different
screensets, much as you might swap between different computer monitors.
scroll bar and scroller Gray beam at the edge of a window. A movable box inside the
beam is used to select the displayed project section in the window.
