I'm following a tutorial about beat detection for music and I was slightly confused about this sentence:
"From the FFT we obtain 1024 complex numbers. We compute the square of their module and store it into a new 1024 buffer."
What does it mean by the square of their module? Is the module just the absolute value of the complex number, ie. sqrt( Re(z)^2 + Im(z)^2 ) ?
I can follow the rest of it, it's just I'm not quite sure of the terminology here.
