Audio Synthesis ep7: The Op-Amp Integrator

Описание: An op-amp, a resistor, and a capacitor make a circuit that can do calculus!

The op-amp integrator will be a basic building block of oscillators,
filters, AGC circuits, and who knows what else?

I don't have an immediate audio use yet, but I need one on a side
project for this channel, so I'm presenting it now.

As always, supplementary material is on the project GitHub:
