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.

Claim (Index 3):
The method according to  claim 1 , wherein the determining the similarity coefficients, corresponding to similarities between the first sub-fingerprint sequence and the second sub-fingerprint sequence, further comprises:\n performing selection operations, each selection operation including selecting a number of first sub-fingerprints from the first sub-fingerprint sequence and a same number of second sub-fingerprints from the second sub-fingerprint sequence; and determining each of the similarity coefficients based on the selected first sub-fingerprints and second sub-fingerprints from a respective one of the selection operations.
