This technology relates to the decorrelation of audio signals for use in surround sound techniques. Decorrelation improves listener envelopment and spatial immersion, but prior techniques suffer from unwanted timbre coloration and are computationally expensive. The present technology improves decorrelation by utilizing a pseudorandom sequence and a reciprocal of the pseudorandom sequence to convolve the audio signal into the desired number of output signals.
