pyFDN.poletti_allpass# pyFDN.poletti_allpass(g, U)[source]# Create Poletti’s MIMO unitary reverberator (allpass FDN). From Poletti, M. (1995). A unitary reverberator for reduced colouration in assisted reverberation systems. INTER-NOISE and NOISE-CON, 5, 1223–1232. Parameters: g (float) – Scalar feedback gain (e.g. 0.7). U (ndarray) – Unitary (orthogonal) feedback matrix. Returns: A, B, C, D – Delay state-space matrices: A = -g*U, B = (1+g)*I, C = (1-g)*U, D = g*I. Return type: tuple[ndarray, ndarray, ndarray, ndarray]
