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 SNR as in high SNR environments and at the same time it performs de-reverberation of the received signals. The solution is ideal for electronic communication devices such as mobile phones, portable computers and virtual assistants in smart speakers where it is desired to extract useful speech signals hidden in various noise fields. The flexibility offered by ExAudio’s solution allows for flexible microphone positioning and arbitrary placement of the self adaptive device in the actual environment.
