What is the word whose definition is 'the background laugh on tv shows'?

Tv shows (especially comedy shows) have a background audience laughter and I remember there's a word whose synonym is the background laughter on tv shows. But, I'm not able to identify the word. Any of you know the word? It is not laugh track or any other word given here http://en.wikipedia.org/wiki/Laugh_track. I distinctly remember that the word doesn't have 'laugh' in it.


Are you possibly thinking of 'sweetening'?

In television sweetening refers to the use of a laugh track in addition to a live studio audience. The laugh track is used to "enhance" the laughter for television audiences, sometimes in cases where a joke or scene intended to be funny does not draw the expected response, and sometimes to avoid awkward sound edits when a scene is shortened or more than one take is used in editing.


It's canned laughter - often used today in broadcasting to simulate the reaction of a nonexistent live audience. [c. 1900]
