1. A device comprising:
a receiver configured to receive an encoded bitstream from a second device, the encoded bitstream including a temporal mismatch value;
a decoder configured to:
decode the encoded bitstream to generate a first frequency-domain output signal and a second frequency-domain output signal;
perform a first inverse transform operation on the first frequency-domain output signal to generate a first signal;
perform a second inverse transform operation on the second frequency-domain output signal to generate a second signal;
based on the temporal mismatch value, map one of the first signal or the second signal as a decoded target channel; and
perform a shift operation on the decoded target channel based on the temporal mismatch value to generate an adjusted decoded target channel; and
an output device configured to output a first output signal and a second output signal, the second output signal based on the adjusted decoded target channel.
