I have a long-standing interest in sound fx and their production, especially since I took a course in university on electro-acoutsic composition, which was all about the production and manipulation of sound. This same interest played a part in my Writers of the Future Grand Prize winning story, “Saturn in G Minor.”
There’s some video available on the BBC website that’s a guided tour of the BBC’s old Radiophonic Workshop by two of the sound engineers. Now, this Radiophonic Workshop is kind of a sound fx candy shop, and where the sounds for Doctor Who and Blake’s 7 were produced. The main clip features a how-to on making your own Dalek voice.
Check it out here, and be sure to watch (and listen!) to some of the other fascinating clips.
