Abstract:
A method of encoding audio channels includes receiving two or more channels at an encoder and identifying a target channel and a reference channel. The target channel and the reference channel are identified from the two or more channels based on a mismatch value. The method also includes generating a modified target channel by temporally adjusting the target channel based on the mismatch value. The mismatch value is indicative of an amount of temporal mismatch between the target channel and the reference channel. The method also includes determining a temporal correlation value indicative of a temporal correlation between a first signal associated with the reference channel and a second signal associated with the modified target channel. The method also includes comparing the temporal correlation value to a threshold. The method further includes generating missing target samples based on the comparison, a coder type, or both.

Claim (Index 28):
An apparatus comprising:\n means for identifying a target channel and a reference channel, the target channel and the reference channel identified from two or more channels based on a mismatch value; means for generating a modified target channel by temporally adjusting the target channel based on the mismatch value, the mismatch value indicative of an amount of temporal mismatch between the target channel and the reference channel; means for determining a temporal correlation value indicative of a temporal correlation between a first signal associated with the reference channel and a second signal associated with the modified target channel; means for comparing the temporal correlation value to a threshold; and means for generating, based on the comparison, missing target samples using at least one of a reference frame based on the reference channel or a target frame based on the modified target channel, wherein the first signal corresponds to a portion of the reference frame, and wherein the second signal corresponds to a portion of the target frame.
