Abstract
A method comprises: receiving a first audio stream that conveys audio content and a second audio stream that conveys the audio content and is delayed relative to the first audio stream by a time delay; one-sided filtering first audio segments of the first audio stream to pass only positive frequencies of the first audio segments to first filtered audio segments; one-sided filtering second audio segments of the second audio stream to pass only positive frequencies of the second audio segments to second filtered audio segments; cross correlating the first filtered audio segments against corresponding ones of the second filtered audio segments, to produce cross-correlation results; detecting a peak indicated by the cross-correlation results; and estimating the time delay based on a position of the peak, to produce an estimated time delay.
