TEMPORAL OFFSET ESTIMATION

A method of non-causally shifting a channel includes estimating comparison values at an encoder. Each comparison value is indicative of an amount of temporal mismatch between a previously captured reference channel and a corresponding previously captured target channel. The method also includes smoothing the comparison values to generate smoothed comparison values based on historical comparison value data and a smoothing parameter. The method further includes estimating a tentative shift value based on the smoothed comparison values. The method also includes non-causally shifting a target channel by a non-causal shift value to generate an adjusted target channel that is temporally aligned with a reference channel. The non-causal shift value is based on the tentative shift value. The method further includes generating, based on reference channel and the adjusted target channel, at least one of a mid-band channel or a side-band channel.
