摘要：A design of variable filters is proposed based on frequency response masking technique and frequency warping. Instead of using traditional masking filters, the masking filters in the proposed method are obtained by nonlinear transformation to a prototype filter using frequency wrapping. The design process is given and the mapping between the final filters and the control parameters are deduced. Experiments illustrate the effectiveness of the proposed method.
