Abstract:
A system, article, and method of acoustic dereverberation factoring the actual non-ideal acoustic environment.

Claim (Index 1):
A computer-implemented method of acoustic dereverberation comprising:\n receiving, by at least one processor, multiple audio signals comprising dry audio signals divided into time-frames and contaminated by reverberations formed by objects in or forming the actual acoustic environment wherein the reverberations comprise reverberation components and residual reverberation components; de-correlating, by at least one processor, past time-frames from a current time-frame to generate multichannel estimates of residual reverberations; performing, by at least one processor, post-filtering by generating an interference matrix using the multichannel estimates of residual reverberations; and applying the interference matrix to reduce residual reverberation components.
