An auditory model is described which makes use of a filter bank with filters having a deep notch on the high frequency side with an associated 180 degree jump in phase, analogous to those previously observed in the responses of single hair cells at lower frequencies. The model is being simulated on a DSP32C processor equipped workstation using DSPlay flowdiagram system design software. It is shown how robust frequency analysis can be carried out with this model, which is also being used for feature extraction experiments. Keywords: Auditory model, Filter bank, Frequency analysis, feature extraction.
