Audio Post Production Knowledge Base
Welcome to TriggerTone — the searchable online guide to audio post production terminology.
For more than a century, those who work with audio have developed a vocabulary all their own - a lexicon where cans are worn over your ears, clipping has nothing to do with coupons, bias never refers to favoritism, sweetening contains no sweetener, a matrix does not star Keanu Reeves, and "wow" is one thing you never want to hear.
TriggerTone signals the start of your search through the multitude of terms used in audio post. Curious why motor boating has sunk your track or how an anomaly with a name as innocuous sounding as flutter could cause so many rejections? The definitions herein were written for professionals not necessarily familiar with the physics of sound or the mind numbing details of an audio engineering textbook. Rather, the goal of TriggerTone is to provide concise, clear interpretations of terms as they relate to audio post embellished with sound clips and illustrations where helpful.
The gate is open; soon your head will be filled. To get you started, please remember that in the world of sound you do not need to layback to laydown, and you absolutely can not eat the pancakes.

Artifacting can occur regardless 
Trigger Tone
A trigger tone is a 12kHz sine wave that was used to "trigger," or turn on, the surround channel of a discrete LCRS (Left channel, Center channel, Right channel, Surround channel) Cinemascope™ print.
Early LCRS surround mixes for Cinemascope films contained very little surround
Restoration
Restoration is the removal or repair of anomalies in a soundtrack that may have resulted from wear and tear or technical errors induced in the audio program since its original production.
The process of restoration can be accomplished to differing degrees. A light restoration may include the
