Now here’s an interesting site. S107.net. It’s a resource that lists the voice samples used in various tracks. Unsurprisingly, Sci-fi films and TV shows are the most popular sources. I’m not sure if it’s still updated – there doesn’t seem to be anything that I could see from the last two or three years. I came across it whilst looking for the source of the sample on Future Sound Of London’s “Among Myselves” which, I discovered, was from David Cronenberg’s Scanners.
