A simple, accurate and efficient variable fractional delay (VFD) IIR filter is presented. The method is based on the interpolation of pole loci of maximally-flat allpass fractional-delay filters. The responses of the proposed VFD filter for different fractional delay values are simulated and the approximation errors are shown to be very small.
