Anyone know a guide to making these in their various forms, and maybe some good uses of them too?
idk just make a melody or something??? put chords there???
What do you mean? Like using physical FFT with real electronics? With code? With other sounds?
this is the vaguest post i have seen
will you specify what you want to create

also i'm not helping you if it's a megalo bc those are sacreligious

anyways just reply to this or message me in chat and i'll gladly help you
🔲🌊 there you go i made it
A 555 is gonna be your best bet, and is a great introduction into digital electronics.

EvilMadScientist, one of my favorite blogs, has a great macro version as a kit. It can help you understand the inner workings of the 555:

A square wave is pulse width modulation in the human-audible sound frequency spectrum, 20Hz-20,000Hz.

Pulse width modulation PWM is a fancy name for turning something on and off or moving between 2 states to control something else.

How long you keep it on vs. off is called the duty cycle.

If the duty cycle is 50% you get a square wave.

if it's less you get a nasal sound. 

if you vary the duty cycle over the length of the sound you get interesting effects.

but OS can't do that.
