Replace mode A type of overwrite recording mode where the currently specified audio
region in the Arrange area is replaced with the incoming signal. To activate Replace mode,
click the Replace button in the Transport bar.

resonance A term generally associated with filters, particularly those of synthesizers.
Resonance emphasizes the frequency range surrounding the cutoff frequency. See cutoff
frequency.

reverb Reverb(eration) is the sound of a physical space. More specifically, the reflections
of sound waves 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 sound waves to reach the walls and bounce back to your ears is very short,
so the reverb effect will probably not even be heard.

ReWire An audio streaming and synchronization technology from Propellerhead software.
The output of ReWire applications can be routed into (and processed with) the
Logic Express Mixer. Logic Express can also control the transport operations of ReWire
programs. Further to these functions, Logic Express instrument tracks can drive the
software instruments of ReWire applications.

ritardando A gradual slowdown of tempo (see tempo).

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 The Logic Express 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.

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 Express 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 Express, 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.
