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; interpolate a subset of the set of target samples using an interpolation factor that is based on the variation and a spreading factor to generate a set of estimated samples, the spreading factor corresponding to a value determined based on at least one characteristic of one or more audio channels; replace the subset of the set of target samples with the set of estimated samples to generate an adjusted set of target samples, the adjusted set of target samples configured to reduce an amount of discontinuity near boundaries of target frames associated with the target channel; 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.
