Sample Rate
Sample Rate is the rate at which samples of an Analogue signal are taken to create a Digital image of that signal.

Sampler
A Sampler is a unit capable of recording, storing and playng back audio samples.

Shelving
This is a type of filter that affects all frequencies above or below a threshold frequency.

Sibilant
having, containing, or producing the sound of or a sound resembling that of the s or the sh in sash.

Sine Wave
A sine is a curved, flowing wave known for its smooth sound.

Slide Guitar
Using a device other than fingers to press the strings on a traditional guitar, beer bottles, metal or glass cylinders over the finger for example. "Open tuning" is used a lot for this kind of thing. The true description is actually for a "Lap top Steel" guitar. One made for this purpose.

SMPTE
Society of Motion Picture and Television Engineers. SMPTE also refers to a common standard for measurement of Intermodulation distortion (IM) and a reference code for the identification of film or video frames. SMPTE code is often used for the synchronisation of two or more audio playback devices.

SMPTE -LTC
Longitudinal or Linear Time Code refers to SMPTE striped along the tape track and is common for tape machines.

SMPTE -VITC
Vertical Interval Time Code, a.k.a "vitsee", means SMPTE timecode that is placed into the space between video frames. Once "burned in" between frames it is called BITC or "bitsee".

SMPTE Time Code
Frame edge lock for audio and video equipment. SMPTE is calculated in:

Hours:Minutes:Seconds:Frames

Solo
Many mixing consoles provide a feature that allows individual input tracks, groups or a combination of solo signals to be routed to the monitors without other signals AND without altering the main mix signal.

Song Form

Spill
This is the term applied to acoustic interference from unwanted source sounds.

Subtractive Synthesis
This type of synthesis takes a broad band signal, sometimes in conjunction with some form of periodic signal, and subtracts frequencies in order to leave the desired output signal.

Synthesizer (Synthesiser)
A synthesizer is an electronic music device that allows the control of the pitch, timing and tone in the generation of one or more source audio signals. Source audio signals can be those produced by a tone or wave form generator, or based upon an audio sample.
