This circuit generates a sine wave and a cosine wave. It combines two integrators. Since the integral of a sine is a negative cosine, and the integral of a cosine is a sine, we can generate both waves by feeding the output of each integrator into the input of the other.

To hear the waveform, increase the simulation speed and press the Play button.
