AB  - Recently, we proposed an adaptive beamformer with the target to simulate a highly directive microphone, as opposed to the conventional signal-to-noise ratio optimization target. It is shown that by applying this beamformer in different ways to a coincident cardioid or tailed stereo cardioid signal pair, audio channels suitable as front left, front right, surround left, and surround right audio channels can be generated. It is also described how to generate a center channel from the same microphone signals. While the proposed surround sound generation is not as flexible as linear B-Format decoding in terms of determining the direction of the response for each channel, the directional responses of the audio channels overlap less resulting in higher channel separation.
