Patent ID: 7840401

Claim:
A method of decoding an audio signal, comprising: receiving, in a computer-readable medium selected from the group consisting of a non-volatile computer-readable medium, a volatile computer-readable medium, and combinations thereof, an audio signal including a downmix signal of a time domain and spatial information, the spatial information being delayed within the audio signal according to a first scheme; converting, by a processor, the downmix signal of the time domain according to a second scheme; delaying, by a processor, the downmix signal converted according to the second scheme by an amount of time substantially equal to a difference between an amount of delay of the spatial information within the audio signal and an elapsed time of converting the downmix signal of the time domain according to the second scheme; combining, by a processor, the delayed downmix signal with the spatial information; generating, by a processor, an output audio signal using the downmix signal and the spatial information, the output audio signal including at least two channel signals; and outputting the output audio signal through an output unit.
