摘要:
It is shown an audio processor 50 for processing an audio signal 55. The audio processor comprises an audio signal phase measure calculator 60 configured for calculating a phase measure 80 of an audio signal for a time frame 75a, a target phase measure determiner 65 for determining a target phase measure 85 for said time frame 75a, and a phase corrector 70 configured for correcting phases 45 of the audio signal 55 for the time frame 75a using the calculated phase measure 80 and the target phase measure 85 to obtain a processed audio signal 90.
