To convert a sound file to a different sample rate and bit depth.
resample
The reverberant sound produced by an acoustic space, such as a room or concert hall. Reverb consists of
reverb
dense, discrete echoes that arrive at the ear so rapidly that the brain can't separate them. Adobe Audition offers three
reverb effects: Studio Reverb, Reverb, and Full Reverb.
A technology for synchronizing audio applications created by Propellerhead Software.
ReWire
(Root-mean-square) A mathematical formula used to determine the average amplitude of an audio selection.
RMS
RMS amplitude reflects perceived loudness better than peak amplitude.
S
Signal-to-noise ratio describes the difference between the highest signal level before distortion and the
S/N ratio
average level of the noise floor. In most analog systems, such as microphone preamps, the S/N ratio is around 92 dB.
A digital snapshot of an audio waveform at a particular point in time. In digital audio, a series of numeric
sample
samples reproduces an entire waveform, with higher sample rates producing increased frequency response. (Note
that musical samplers use the term sample to describe a digital recording, rather than a digital snapshot.)
The number of samples per second. Higher sample rates produce increased frequency response but
sample rate
require more disk space. To reproduce a given audio frequency, the sample rate must be at least double that
frequency. (See "Nyquist frequency" on page 277.)
A musical device that records and plays digital sounds (known as samples in this context) and lets you edit
sampler
and store those sounds.
A programmable piece of software or hardware that can record and play a sequence of musical events,
sequencer
such as samples, pitches, and rests. Most modern sequencers are MIDI-based. (See "MIDI" on page 276.)
A multitrack project in Adobe Audition. Session files are stored with the extension .ses and contain details
session
such as mixing and effects settings. Session files don't contain audio data; instead they contain pathnames pointing
to the sound files used in the session.
(Society of Motion Picture and Television Engineers timecode) A timing reference used to
SMPTE timecode
synchronize two devices. SMPTE timecode is divided into hours, minutes, seconds, and frames.
A hardware device that lets your computer play and record audio.
sound card
A wave of air molecules. Humans can hear sound waves with frequencies of 20 to 20,000 Hz.
sound wave
Editing audio using a display that visually represents audio frequencies. In spectral displays, bass
spectral editing
frequencies appear at the bottom, treble at the top. Volume is represented by color intensity. In Adobe Audition, you
perform spectral editing to remove noise or process specific frequency ranges.
A signal with a left and right channel, allowing for spatial placement of sounds.
stereo
To copy SMPTE timecode to a single track of a multitrack tape so remaining tracks can be synchronized with
stripe
other devices.
T
The rhythmic speed of music, normally measured in beats per minute. (See "beats per minute (bpm)" on
tempo
page 273.)
An audio or digital signal that synchronizes time between multiple devices. The most common forms are
timecode
SMPTE and MIDI timecode.
