Abstract
Methods and systems for processing an audio signal are provided. The method includes generating a pseudorandom sequence and generating at least one reciprocal of the pseudorandom sequence such that the at least one reciprocal is substantially decorrelated with the pseudorandom sequence. The pseudorandom sequence and the at least one reciprocal form a set of sequences. The method further includes convolving the audio signal with the set of sequences to generate a corresponding number of output signals and providing the number of output signals to a corresponding number of loudspeakers.
