摘要： Systems and methods for performing sound source localization are provided. In one aspect, a method for locating a sound source using a computing device subdivides a space into subregions. The method then computes a sound source power for each of subregions and determines which of the sound source energies is the largest. When the volume of the subregion is less than a threshold volume, the method outputs the subregion having the largest sound source power. Otherwise, the stages of partitioning, computing, and determining the subregion having the largest sound source power is repeated.

摘要： Embodiments of the present invention are directed to audio-conference communication systems that enable audio-conference participants to identify which of the participants are speaking. In one embodiment, an audio-communication system comprises at least one communications server, a plurality of stereo sound generating devices, and a plurality of microphones. Each stereo sound generating device is electronically coupled to the at least one communications server, and each microphone is electronically coupled to the at least one communications server. Each microphone detects different sounds that are sent to the at least one communications server as corresponding sound signals. The at least one communications server converts the sound signals into corresponding stereo signals that when combined and played over each of stereo sound generating devices creates an impression for a person listing to any one of the stereo sound generating devices that each of the sounds emanates from a different virtual location in three-dimensional space.
