Abstract:
1. A method for processing audio signals, comprising: (a) generating first and second cardioid signals from first and second microphone signals; (b) generating a first adaptation factor; (c) applying the first adaptation factor to the second cardioid signal to generate an adapted second cardioid signal; and (d) combining the first cardioid signal and the adapted second cardioid signal to generate a first output audio signal corresponding to a first beampattern having no nulls for at least one value of the first adaptation factor, and (e) applying noise suppression processing to the first output audio signal to generate a noise-suppressed output audio signal, wherein the noise suppression processing is controlled based on the first adaptation factor, wherein: in Scenario A: in Scenario B: in Scenario C: in Scenario D:
