Claim Text:
1. A method of processing a multichannel signal, said method comprising: for a first pair of channels of the multichannel signal, calculating a first plurality of directional fitness measures, wherein each among the first plurality of directional fitness measures is based on a corresponding different one among a plurality of candidate directions; for a second pair of channels of the multichannel signal that is different than the first pair, calculating a second plurality of directional fitness measures, wherein each among the second plurality of directional fitness measures is based on a corresponding different one among the plurality of candidate directions; and based on the first plurality of directional fitness measures and the second plurality of directional fitness measures, selecting a first direction from among the plurality of candidate directions, wherein each of the first plurality of directional fitness measures is based on a difference, at a first frequency component of the multichannel signal, between the channels of the first pair, wherein each of the second plurality of directional fitness measures is based on a difference, at the first frequency component, between the channels of the second pair, and wherein said selecting the first direction from among the plurality of candidate directions comprises determining a minimum directional error among the first plurality of directional fitness measures and the second plurality of directional fitness measures.
