Real Time Room Acoustic Simulation by a Reflection-Diffusion

Abstract:- A new model of artificial reverberator for real-time room acoustic response simulation is proposed. It’s structure is inspired by Jot’s model, but with the introduction of a not so much previously exploited aspect of the generation of the reverberation phenomenon. In fact, together with the reflection component, it also takes into account the presence of a diffusion component. The proposed reverberator makes massive use of All Pass filters in order to mix the multiple echoes produced by Comb filters, and to increase the echo density. Diffusion and reflection feedback matrices have been introduced, in order to adapt the reverberator to different kind of rooms
