... manifold. For further information on derivation and implementation of this hard constraintrefer to [1] and references therein.The closed form analytical expressions for first and second order informa-tion ... the center frequency for each subband m, T is the samplingperiod, and N is the gammatone filter order (N = 4). For a sampling periodof 8000 Hz, the total number of subband is M = 17, so m = ... equation:where is the amount of forward masking (dB) in the mth band,is the time difference between the masker and the maskee in milliseconds,L(t,m) is the masker level (dB), and a, b, and c, are parameters...
