1. A device comprising an encoder configured to: receive a reference channel and a target channel, the reference channel including a set of reference samples, and the target channel including a set of target samples; determine a variation between a first mismatch value and a second mismatch value, the first mismatch value indicative of an amount of temporal mismatch between a first reference sample of the set of reference samples and a first target sample of the set of target samples, the second mismatch value indicative of an amount of temporal mismatch between a second reference sample of the set of reference samples and a second target sample of the set of target samples; adjust the set of target samples based on the variation to generate an adjusted set of target samples; and generate at least one encoded channel based on the set of reference samples and the adjusted set of target samples; and a network interface configured to transmit the at least one encoded channel.
