This article is plagiarized from the Wikipedia article on gated reverb. I went to Wikipedia to find an example of the sound (because, of course, this article about a sound effect doesn't include an example, another example of shitty writing) and saw at least one paragraph in the summary had been lifted verbatim.
It would be good to hear examples of this effect, alright. I’d like to hear how something sounds with 1) no reverb, 2) with reverb applied and 3) with the reverb gated.
The Wikipedia article goes deeper into the history; the featured article has no mention of Steve Lillywhite and others who were using similar techniques before Hugh Padgham worked on Peter Gabriel’s third album. It also has a good explanation of the three different ways of creating this effect: https://en.wikipedia.org/wiki/Gated_reverb
