Abstract :
Frequency warping using all pass structures or Laguerre filters has increasingly found applications in audio signal processing due to having a good match with auditory frequency resolution. Kautz filters are an extension where the frequency warping and related resolution can have more freedom. We discuss the properties of Kautz filters and how they meet typical requirements found in modeling and equalization of audio systems. Case studies include transfer function modeling of the guitar body and loudspeaker response equalization
