The noise of the door on the starship "Enterprise NCC-1701" has a very strange sound, especially at the end (a strange squeak-noise). So I had analysed the original audio file from the original series of STAR TREK and wanted to know, what's happens, when I slow down drastically the tempo of it. You get a big surprise in the middle of the video! In our company of a world-renowned media corporation, we have agreed with at least another 3 sound engineers that it is indeed a male voice that can be heard there!

However, such a thing was not really unusual, because in former times one worked with quite simple, acoustic means. One put microphones into a flower vase and spoke from above into this, and so a strange, easily reverberated "robot voice" developed. Or one blew directly on a microphone, recorded there on a tape recorder and set the speed accordingly slower. Add some reverb and the big explosion was perfect!
