AUDIO PROCESSOR AND METHOD FOR PROCESSING AN AUDIO SIGNAL USING VERTICAL PHASE CORRECTION

摘要

It is described an audio processor (50') for processing an audio signal (55). The audio processor (50') comprises a target phase measure determiner (65') for determining a target phase measure (85') for the audio signal (55) in a time frame (75), a phase error calculator (200) for calculating a phase error (105') using a phase of the audio signal (55) in the time frame (75) and the target phase measure (85'), and a phase corrector (70') configured for correcting the phase of the audio signal (55) in the time frame using the phase error (105').
