Abstract
Two-channel input audio signals are processed to construct output audio signals by decomposing the two-channel input audio signals into a plurality of two-channel subband audio signals. Separately, in each of a plurality of subbands, at least three generated subband audio signals are generated by steering the two-channel subband audio signals into at least three generated signal locations. The output audio signals are synthesized from the generated subband audio signals. The steering applies differing construction rules in at least two of the plurality of subbands.
