FYI: I'm one who never took a signals course in college. I have some basic idea of complex numbers, but really have no clue why they should relate to sound / audio signals at all.
It is called the complex method. Write the signal as the real part of A*exp(i*w*t). Then the phase trigonometric phase computations become simpler in view of that exp(x + y) = exp(x)*exp(y) also for complex numbers x, y.
