Patent ID: 7987281

Claim:
A method of enhancing a surround-sound audio signal delivered over a network, the method comprising: receiving streaming audio at a client location; converting the streaming audio into at least two channels of receive audio; and enhancing the at least two channels of receive audio for playback by the client with one or more processors, said enhancing comprising: correcting a perceived height of an apparent sound stage associated with the at least two channels of receive audio by at least applying one or more high pass filters to the at least two channels of receive audio to create vertically-corrected audio; enhancing a bass response associated with the vertically-corrected audio to produce vertically-corrected and bass-enhanced audio, said enhancing the bass response comprising: filtering the at least two channels of receive audio at a first bass frequency with a first band pass filter; filtering the at least two channels of receive audio at a second bass frequency with at least a second band pass filter, wherein the second bass frequency is different than the first bass frequency; and filtering the at least two channels of receive audio at a third bass frequency with a third band pass filter, wherein the third bass frequency is different than the first and second bass frequencies; and correcting a perceived width of the apparent sound stage of the vertically-corrected and bass-enhanced audio by at least equalizing a difference signal present in the vertically-corrected and bass-enhanced audio such that lower and higher difference signal frequencies are boosted relative to mid-band difference signal frequencies between the lower and higher difference signal frequencies.
