"The main reason we use complex numbers in electronic music is
because they magically automate trigonometric calculations. We
frequently have to add angles together in order to talk about the
changing phase of an audio signal as time progresses (or as it is
shifted in time, as in this chapter). It turns out that, if you
multiply two complex numbers, the argument of the product is the sum
of the arguments of the two factors."
