Latest Patents
One of Noah Stein's latest patents involves a method for signal source separation. This innovation utilizes a microphone with closely spaced elements to acquire multiple signals, allowing for the separation of a desired source from interfering signals. The approach combines direction-of-arrival information with structural data, enabling effective signal separation even when microphone elements are closely spaced. In some instances, all microphone elements are integrated into a single micro-electrical-mechanical system (MEMS).
Another significant patent addresses time-frequency directional processing of audio signals. This method involves acquiring parallel signals from a set of closely spaced microphones and employing a multi-tier computing approach. Some processing occurs at the user's device, while additional processing is conducted on server computers. The acquired signals are analyzed using time versus frequency estimates, and a non-negative matrix or tensor factorization approach is utilized to identify multiple sources, each associated with a specific direction of arrival.
