Auditory segregation model

  

Figure: Auditory segregation model.

The auditory segregation model shown in Fig. consists of three parts: (a) auditory filterbank, (b) separation, and (c) grouping. The auditory filterbank is constructed using a gammatone filter as an ``analyzing wavelet''. The separation block uses physical constraints related to heuristic regularities (ii) and (iv). The grouping block uses physical constraints related to heuristic regularities (i) and (iii), and signal reconstruction in the grouping block is done with the inverse wavelet transform. In this model, the separation block follows the formulation of the problem of segregating two acoustic sources.
