Audio fingerprint retrieval library updating method and device, equipment and medium

Abstract

The invention discloses an audio fingerprint retrieval library updating method and device, equipment and a medium, and the method comprises the steps: obtaining a target song ID from a to-be-extracted feature queue when it is monitored that the to-be-extracted feature queue is non-empty; performing feature extraction on the to-be-processed audio data corresponding to the target song ID to obtain target audio feature data; storing the target song ID into a to-be-inserted fingerprint queue, and storing the target audio feature data into a preset storage area according to the target song ID; when it is monitored that the to-be-inserted fingerprint queue is non-empty, obtaining an earliest stored target song ID from the to-be-inserted fingerprint queue; encoding target audio feature data corresponding to the earliest stored target song ID to obtain a corresponding target audio fingerprint; and sending the target audio fingerprint to a target online server, so that the target online server inserts the target audio fingerprint into an audio fingerprint retrieval library. In this way, the audio fingerprint retrieval library can be updated in real time.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, equipment, and medium for updating an audio fingerprint retrieval database. Background technique [0002] In services such as listening to songs and recognizing songs online, the audio fingerprint retrieval library will be used. In order to ensure that the listening and song recognition service can identify as many songs as possible, the audio fingerprint retrieval library needs to be updated. The existing method of updating the audio fingerprint retrieval library is to take the day as the unit, take the service offline during a specific time period of the day, and then add the audio fingerprint to be updated to the audio fingerprint retrieval library when the service is offline, and then Restart the service, that is, the update of the audio fingerprint retrieval library needs to be performed offline in units of days. In the process of implementing ...
