hi, can you explain the principle of this type of sound? Mixture of two "curves"?

hi, can you explain the principle of this type of sound? Mixture of two "curves"?

It's actually a mix of 4 oscillators, each 1 Hz away from the next, i.e. at 400, 401, 402 and 403 Hz.
They start beating because the peaks keep wandering relative to another. I also change the "waveform"
in between, i.e. the tone envelope representing high and low and each waveform is played at 3
different, increasing frequencies

Here's a great (albeit a bit long) video by the great guys at Khan Academy explaining the beating effect:

And even more! I love those harsh sounds never heard before on the CPC :)
