Your tension has been exterminated

« previous post | next post »

BBC Research and Development offers a discussion of the analogue ring modulator used to create the Dalek voice effect, along with an explanation of how a digital version was programmed in the great new WebAudio API.

Note that the 30-Hz modulation frequency is right in the flutter-fusion boundary region discussed here.

    Haha… not exactly relaxing, but kind of fascinating!

    That poor Dalek, doing his best to get with the programme but still subject to irrational prejudice from humans on account of the way he talks. Can he help it if his voice is in the flutter-fusion boundary? Or if the prosody of Dalek speech happens to resemble a human getting into a rage? Considered properly, Dalek culture has always shown a commendable willingness to communicate with aliens in their own language, as demonstrated in one of my favourite episodes, "Journey's End":

    "Exterminieren! Exterminieren! Halt! Sonst werden wir Sie exterminieren! Sie sind jetzt ein Gefangener der Daleks! Exterminieren! Exterminieren!"

    [(myl) Good point. It may help in overcoming anti-Dalek prejudice to listen to Dalek Winston Churchill:

    Or Dalek Barack Obama:

    Or Dalek Sarah Palin:

    Or Dalek Ira Glass:

    Or Dalek Rush Limbaugh:

    Or, indeed, Dalek synthetic Nietzsche:

    Putting it all together, they're just like us, only modulated differently:
