First Claim
Patent Images
1. A method of processing an audio signal, comprising:
- receiving a downmix signal and spatial information;
performing a complexity domain conversion on the downmix signal; and
combining the converted downmix signal and the spatial information, wherein the combined spatial information is delayed by an amount of time that includes an elapsed time of the complexity domain converting.

4. A method of processing an audio signal, comprising:
-
receiving an audio signal of which synchronization between a downmix signal and spatial information is matched according to a first decoding scheme; and
compensating for a time synchronization difference between the downmix signal and the spatial information, if the received audio signal is decoded according to a second decoding scheme. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. A system for processing an audio signal, comprising:
-
a first decoder configured for receiving a downmix signal and spatial information;
a converter operatively coupled to the first decoder and configured for performing a complexity domain conversion on the downmix signal; and
a second decoder operatively coupled to the converter and configured for compensating at least one of the converted downmix signal and the spatial information for time delay resulting from the converting, and for combining the converted downmix signal and the spatial information.
