Technology

ExAudio’s unique Blind Signal Extraction Technology ExAudio offers a unique solution to the problem of blindly extracting wave propagating signals using one or more sensors without having any priory knowledge about source’s or sensor’s positions. The solution operates simultaneously in both the temporal and the spatial domain using one global optimization criteria, with no constraints on the number of sources vs. the number of sensors. The solution is Signal-to-Noise Ratio (SNR) independent meaning that it operates optimally in both low…
