@GabrielDuquette A sound engineer with an EE background might know of some examples. This is the foundation of digital synths.
@GabrielDuquette ...of a moving point. If that point were just going around the main circle, you'd see classical sine waves.

@GabrielDuquette Fourier analysis is the mathematical theory of breaking down arbitrary waves into a sum of sine-waves. -
@GabrielDuquette In that illustration, the smaller circles (literal epicycles) represent higher-frequency components with lower amplitude. -
@GabrielDuquette As sounds, they correspond to higher but softer harmonics. As graphs, squigglier but smaller. -
@GabrielDuquette One collection of such harmonics approximates a square wave. A different collection gives you a sawtooth. -
@GabrielDuquette In a (technical and carefully qualified) sense, you can do this with *any* wave. That's how digital synths, CDs etc. work. -

@jamesmcn@GabrielDuquette I probably meant analog synth. I only know the math-class-lies version. - 3 more replies
