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 16):
The device according to  claim 13 , wherein the processing circuitry is further configured to:\n perform at least one relative shifting operation on the first sub-fingerprint sequence and the second sub-fingerprint sequence , and calculate at least one similarity coefficient that respectively corresponds to the at least one shift relative shifting operation according to at least one shift result of the at least one relative shifting operation.
