Abstract
Presented herein are techniques for generating a combinatory microphone signal from sounds captured at a microphone array. More specifically, sound signals captured by a microphone array are used to generate first and second directional signals. A cross-power signal is computed from the first and second directional signals. The cross-power signal is converted into an amplitude domain output signal, and a phase of the amplitude domain output signal is reconstructed in order to generate a combinatory microphone signal that is useable for subsequent sound processing operations.
