Abstract
Input audio data portions of a common time window index value generated by multiple microphones at a location are received. Subband portions are generated from the input audio data portions. Peak powers, noise floors, etc., are individually determined for the subband portions. Weights for the subband portions are computed based on the peak powers, the noise floors, etc., for the subband portions. An integrated audio data portion of the common time window index is generated based on the subband portions and the weight values for the subband portions. An integrated signal may be generated based at least in part on the integrated audio data portion.
