Schlappi Engineering Angle Grinder - Silver filter Open-source support is available throughAngle Grinder is a quadrature sine wave oscillator, filter, and distortion effect. The SPIN section is a quadrature sine wave oscillator. The GRIND section compares each phase against the input signal, then subtracts the resulting square waves from the input signal. If the spin section is either damped enough or enough signal is fed into it from the GRIND section then it will stop oscillating and become a state variable filter. The Angle Grinder
