In digital audio, a signal isn't captured in a complete continuous fashion, as in traditional recording. To digitize
Sample
a sound, a number of snapshots, or samples, are taken every second (this number is a product of the sampling rate used)
and are changed into numeric representations. A sample is a single snapshot of the sound, if you will. The term sample
can also refer to the digitally recorded sound itself, though this nomenclature tends to be used more when referring to
digitized sounds used by hardware samplers than in computer-based audio editing.
The sample rate determines the number of times per second to take a snapshot of the audio. Higher sample
Sample Rate
rates produce higher-resolution audio, but at the expense of requiring more disk space. Frequencies of up to one-half the
sample rate can be produced effectively. So, to reproduce a frequency of 10Khz, a sample rate of at least 20Khz must be
chosen. (See Nyquist Frequency.)
A device that records and plays digital sounds (samples) many times with features to edit and store the samples.
Sampler
Small Computer Systems Interface. Pronounced "skuzzy", SCSI is a standard for attaching components (such as
SCSI
hard drives and CD-ROMs) to a computer. It allows for multiple devices to be daisy-chained to the same controller, and
for very fast data transmission.
A programmable electronic device which can play a stepped order (sequence) of musical events, such as
Sequencer
samples, pitches, and rests.
A Session in Adobe Audition is a multitrack project. Actually, "session" can refer to the project itself (as in "your
Session
session") or to the act of working on the project (as in "during your session"). A Session is stored as a file on your hard
disk with the extension .ses, and contains the details of the project, such as what tracks contain what audio files, volume
levels, and envelope information, among other things. Session files don't actually store the audio data in them; instead
they point Adobe Audition to where it can find and load the sound files used in the project.
The workspace where audio data shows up and can be manipulated in Adobe Audition's Multitrack
Session Display
View.
Audio files with an .smp extension are used by Turtle Beach's SampleVision program. The format supports only
SMP
mono 16-bit audio. If your data is in a different format, you'll be asked to convert it before saving. SMP format also
supports loop points, which can be edited using Adobe Audition's Cue List.
Shortcuts are used to speed up the editing process by allowing you to execute almost any command in Adobe
Shortcut
Audition from your computer keyboard. For example, instead of using your mouse to go to the Edit menu and selecting
Cut to remove the highlighted portion of a waveform, you can simply press Ctrl+X. In Adobe Audition, you can execute
commands from a MIDI keyboard, a sequencer, or any other device capable of issuing a MIDI command. This type of
Shortcut is referred to as a MIDI Trigger. An example of this would be assigning the Play command in Adobe Audition
to the C4 note on your MIDI keyboard.
SMPTE Start Offset
recording will trigger while Adobe Audition is syncing to SMPTE time code.
SMPTE Time Code
synchronize two devices to the same clock. SMPTE time is broken down into hours, minutes, seconds, and frames.
Waves with this file extension are usually Apple AIFF or Next/Sun files. See AIFF or AU.
SND
The offset to the start of a multitrack session. The Start Offset determines when playback and
SMPTE (Society of Motion Picture and Television Engineers) time code is a timing reference used to
