A Binaural Artificial Reverberation Process

A new method of binaural artificial reverberation process is presented divided in two different parts depending on the reflection order. The first consists in a random determination of the image-sources according to the theoretical calculation of the image probability density. The second is based upon time frequency filtering of two correlated white noises. Both of this parts run with statistical parameters which are strongly related to the acoustical and geometrical characteristics of the hall (they are determined over a geometrical calculation of the image-sources for low reflection orders). That provides natural reverberation.
