Aliasing is a commonly-encountered problem in audio signal processing, particularly when memory less nonlinearities are simulated in discrete time. A conventional remedy is to operate at an oversampled rate. A new aliasing reduction method is proposed here for discrete-time memory less nonlinearities, which is suitable for operation at reduced oversampling rates. The method employs higher order anti derivatives of the nonlinear function used. The first order form of the new method is equivalent to a technique proposed recently by Parker et al. Higher order extensions offer considerable improvement over the first anti derivative method, in terms of the signal-to-noise ratio. The proposed methods can be implemented with fewer operations than oversampling and are applicable to discrete-time modelling of a wide range of nonlinear analog systems.
