Abstract

The invention relates to an audio database management method and system. When updating a personal audio database, first, audio data is divided into different sub-segments, the spectral energy of eachsub-segment of the audio data to be compared and the user click rate of the sub-segment are obtained, and the weight coefficient corresponding to the audio fingerprint of the sub-segment are determined based on the spectral energy and the user click rate; the audio fingerprint of the audio data to be compared is compared with the audio fingerprint of the audio data in the personal audio database based on the weight coefficient to obtain a similarity value of the two. The method for calculating the similarity of the audio data fully takes into account the characteristics of the audio data and the usage situation of the user, and can more accurately calculate the similarity between the two audio data. The method also combines system automatic identification with user artificial identification, and effectively improves the accuracy and efficiency of the identification.

Description

technical field [0001] The invention relates to the technical field of audio recognition, in particular to an audio database management method and system. Background technique [0002] Audio fingerprinting is to extract the unique digital features in a piece of audio in the form of identifiers through specific algorithms, which can be used to identify a large number of sound samples or track the location of samples in the database. Audio fingerprint, as the core algorithm of automatic content identification technology, has been widely used in music identification, copyright content monitoring, content library deduplication and TV second screen interaction and other fields. [0003] Audio fingerprint technology extracts the data features in the sound and compares the content to be identified with the established audio fingerprint database. The recognition process is not affected by the storage format, encoding method, bit rate and compression technology of the audio itself. ...
