摘要：
A decoder for decoding an encoded audio signal to obtain a phase-adjusted audio signal is provided. The decoder comprises a decoding unit (110) and a phase adjustment unit (120). The decoding unit (110) is adapted to decode the encoded audio signal to obtain a decoded audio signal. The phase adjustment unit (120) is adapted to adjust the decoded audio signal to obtain the phase-adjusted audio signal. The phase adjustment unit (120) is configured to receive control information depending on a vertical phase coherence of the encoded audio signal. Moreover, the phase adjustment unit (120) is adapted to adjust the decoded audio signal based on the control information.
