System for generating spatial audio with uniform reverberation in real-time communication

Abstract

A real-time communication software application for generating spatial audio with uniform reverberation in a real-time communication session is performed by an electronic communication device. The application is adapted to remove the reverberation of recorded speech signals from far-end participants by the dereverberation approach, render the direct sound parts by filtering the output signals by head-related transfer functions of desired directions, generate reverberant sound parts by convolving the output signals from with uniform room impulse responses or an artificial reverberator, and combine direct and reverberant sound components to generate spatialized speech signals. When speakers and listeners are located in two virtual conference rooms, the reverberation of the two rooms are coupled. The reverberant sound parts are then generated by convolving the output signals and coupled RIRs from the two rooms.
