Abstract:
A method of determining an audio delay and a corresponding device are provided. The first audio data and second audio data are obtained. A first sub-fingerprint sequence of the first audio data and a second sub-fingerprint sequence of the second audio data is extracted. The first sub-fingerprint sequence includes at least one first sub-fingerprint and the second sub-fingerprint sequence includes at least one second sub-fingerprint. Processing circuitry determines similarity coefficients corresponding to similarities between the first sub-fingerprint sequence and the second sub-fingerprint sequence. The processing circuitry determines a matching level between the first sub-fingerprint sequence and the second sub-fingerprint sequence according to the similarity coefficients. The processing circuitry determines, according to the matching level, a delay of the second audio data relative to the first audio data. The method and device can improve calculation precision, thereby correspondingly improving a delay compensation effect, and alleviating a dual sound phenomenon.
