Abstract :
A new IIR adaptive filter for real-time, room acoustic response simulation is proposed, the structure of which derives from Jot´s model of an artificial reverberator. The simultaneous perturbation stochastic approximation (SPSA) algorithm is used to set parameter values. Results show good similarity between the desired and artificial response.
