1. An apparatus comprising:
a receiver configured to receive at least a portion of a bitstream, the bitstream comprising a first frame and a second frame, the first frame including a first portion of a mid channel and a first parameter, the second frame including a second portion of the mid channel and a second parameter; and
a decoder configured to:
generate a first portion of a channel based at least on the first portion of the mid channel and the first parameter; and
in response to the second frame being unavailable for decoding operations, estimate the second parameter by interpolating the first parameter; generate a second portion of the channel based on stereo parameters of one or more preceding frames, the second portion of the channel corresponding to a representation of the second frame, wherein the stereo parameters of the one or more preceding frames include the first parameter, wherein the second portion of the channel is also based at least on the estimated second parameter.
