Audio processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses an audio processing method and device, electronic equipment and a storage medium, and the method comprises the steps: extracting an audio fingerprint of a target audio, obtaining an inverted index table, and enabling the inverted index table to comprise the target audio and the fingerprint information of the target audio; obtaining a fingerprint information representation degree of the target audio according to the fingerprint information of the target audio; and if the representation degree of the fingerprint information of the target audio is lower than the expectation, deleting the fingerprint information of the target audio from the inverted index table. By screening the data in the inverted index table, the memory consumption can be reduced, and the retrieval efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of multimedia data, in particular to an audio processing method, an audio processing device, an electronic device, and a storage medium. Background technique [0002] With the development of Internet and audio fingerprint technology, an audio retrieval method based on audio fingerprint has emerged. This audio retrieval method only needs to extract the audio fingerprint from the audio segment input by the user, and compare the audio fingerprint with the audio fingerprint in the inverted index table. The inverted index table records the mapping relationship between the audio fingerprint and the audio. According to The comparison results can retrieve related audio. This audio retrieval method does not require users to manually input text, and can retrieve audio more conveniently, and is favored by more and more people. In practice, it is found that in this audio retrieval method, if there are too many...

Problems solved by technology

In practice, it is found that in this audio retrieval method, if there are too many audio fingerprints included in the inverted index table, more audio can be retrieved for the user, but the workload of secondary filtering will be increased and a large amount of memory will be consumed to store the inverted index. Arrange the index table; secondary filtering means that after multiple related audios are retrieved according to the fingerprint of the audio segment input by the user, it is necessary to filter out a user-needed audio from the retrieved audios again

If there are too few audio fingerprints included in the inverted index table, the workload of secondary filtering and memory consumption can be reduced, but more audio cannot be retrieved for the user
