Glossary 705

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 span from the start position of the mouse

cursor. All objects touched or enclosed by the rubber band selection envelope will be

highlighted.

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 EXS24 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).

sample rate converter Device or algorithm that translates one sample rate to another.

The Digital Factory menu in Logic’s Sample Editor features a sample rate converter.

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 number keys on the numeric keypad

and the number keys above the keyboard have a different scan code, but use the same

ASCII symbol.
