This paper presents a novel pitch shifting algorithm that achieves latency significantly lower than existing techniques. As such, it provides a solution for various situations such as live performances in which pitch shifting within less than 10ms of latency is desired. Based on IIR filters, oscillators and ring modulations, the proposed algorithm completely differs from previous approaches. This paper presents this novel algorithm in detail and shows how it was implemented. It further compares
