a The auditory nerve image (ANI) is estimated from a mono audio signal and then converted into periodicity pitch image from which we extract different pitch profiles for further analysis. Leaky integration is performed for echoes of 0.1, 1.5 s on the periodicity pitch image to obtain two images of different echo whose Pearsons' correlation index between running columns gives the pitch expectation profile. b Calculation of the rhythmical density from ANI. The operator ⊕ is used to denote the column/row sums of the matrix Zα.
