Problems solved by technology

[0004] It can be seen that audio fingerprint recognition requires a high memory capacity (TB level), which cannot be met by a single server at present.
The existing solution is usually to split the music library, use a large number of servers to build audio fingerprint libraries separately, and search all servers at the same time, this solution will cause unnecessary searches and waste resources

Embodiment Construction

[0027] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0028] figure 1 A flow chart of the method for constructing an audio fingerprint library according to the present invention is shown. understandable, figure 1 The flow diagrams shown are merely schematic, and the steps recited therein may be performed in a different order, performed in parallel, omitted, and / or additional steps may be added. Such as figure 1 As shown, the method for constructing the audio fingerprint library includes extracting the key value 102 of the audio fingerprint and the audio fingerprint; establishing a corresponding relationship 104 between the audio fingerprint with the same key value and th...

Abstract

The invention discloses a method for establishment of an audio fingerprint database. The method includes: extracting audio fingerprints and key values thereof; setting up a corresponding relation between the audio fingerprints with same key values and the key values; distributing the key values and the corresponding audio fingerprints into servers; setting up a corresponding relation between the key values and the servers to set up the audio fingerprint database. The invention further discloses equipment for establishment of the audio fingerprint database and a method and equipment for retrieval of the audio fingerprints according to the audio fingerprint database. Due to the fact that the audio fingerprints and the key values associated with the audio fingerprints are distributed into the servers in a balanced manner, the audio fingerprints and the key values associated with the audio fingerprints in each inquire request can be precisely provided for the corresponding server to complete calculation, and accordingly resource utilization rate is guaranteed to the maximum extent; by means of statistics of access frequency of each key valve of each server during system operation, load balance is optimized, and system throughput capacity is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for constructing an audio fingerprint database and retrieving audio fingerprints. Background technique [0002] Audio fingerprint recognition (commonly known as "listening to music") is an emerging music search technology. This technology extracts digital features called "audio fingerprints" by analyzing the frequency spectrum of audio files, and uses digital features to construct "massive audio fingerprints". Library", deployed on the network server, the client can send the recorded unknown audio clips to the server, the server uses the same algorithm to extract the "audio fingerprint", and then uses the search algorithm to find similar features in the massive audio fingerprint library, and based on the found Several features of the target audio file are speculated, and the result is returned to the client to complete the entire recognition process. [...
