Claim 0:
1. A method for enhancing multi-source audio by multi-source tracking and voice activity detection, comprising:
receiving, via audio input circuitry, one or more multi-source audio signals from a microphone array;
constructing a multi-dimensional space defined by a number of microphone pairs from the microphone array;
computing, for each microphone pair, a time difference of arrival (TDOA) location point corresponding to an azimuth angle and an elevation angle of an incident ray based on a distance and an angle between two microphones in the respective pair;
forming a mesh of TDOA location points by iterating all microphone pairs and all scans of azimuth angles and elevation angles; and
updating a plurality of audio tracks based on the mesh of TDOA location points.
