Zusammenfassung:The invention provides an audio matching method. The method comprises the steps of obtaining a second-level fingerprint of a to-be-matched audio according to first-level fingerprint conversion of theto-be-matched audio; matching in a second-level fingerprint library of a first audio set according to the second-level fingerprint of the to-be-matched audio to obtain a second audio set; and matchingin a first-level fingerprint library of the second audio set according to the first-level fingerprint of the to-be-matched audio to obtain a target audio. the first-level fingerprint of the to-be-matched audio is converted to obtain the second-level fingerprint; the data volume of the second-level fingerprint library composed of the second-level fingerprints is far smaller than that of the first-level fingerprint library composed of the first-level fingerprints; furthermore, the audio set meeting a certain matching degree is obtained by matching the second-level fingerprint of the to-be-matched audio in the second-lev
