Abstract :
A method to simulate a room impulse response using optimum quasi bi-orthogonal (OQB) filters in an octave filter bank structure is demonstrated. It is further shown that the poly-phase adaptive filter structure (PPS) or the log transform can be used to obtain accurate subband reference responses and that equi order filters in the subbands yield satisfactory results
