Abstract
A method of processing each of a first plurality of temporal windows of first and second input audio signals to generate first and second output audio signals comprises (a) detecting a time offset between respective portions of the first and second input audio signals corresponding to a given temporal window by: (i) detecting a correlation between one or more properties of the respective portions according to each of a group of candidate time offsets under test; and (ii) selecting, as a detected time offset for the given temporal window, an offset for which the detecting step (i) detects a correlation which meets a predetermined criterion such as greatest correlation; and (b) for each of a second plurality of temporal windows, generating a portion of the first and second output signals by applying a relative delay between portions of the first and second input audio signals in order to correct one or both of the input audio signals to generate a pair of output audio signals (such as a stereo pair) having a reduced temporal disparity between the audio content of the two signals.
