Abstract

The invention discloses an audio fingerprint generation method, a device and equipment. The method comprises the following steps that: acquiring audio data of a user, and generating a spectrogram anda spectrogram of the acquired audio data, and extracting audio universality features and audio periodicity features associated with the acquired audio data from the spectrogram and the spectrogram, restoring live audio of the acquired audio data according to the audio universality features and the audio periodicity features, and extracting audio fingerprints of the live audio. In this way, the accuracy of extracting the audio fingerprint from the audio data of the user can be improved.

Description

technical field [0001] The present invention relates to the technical field of audio fingerprints, in particular to a method, device and equipment for generating audio fingerprints. Background technique [0002] Audio fingerprinting refers to the extraction of unique digital features in a piece of audio in the form of identifiers through a specific algorithm, which is 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] The existing audio fingerprint generation scheme generally obtains the user's audio data, and directly extracts the audio fingerprint from the acquired audio data to complete the generation of the audio fingerprint of the audio data. The accuracy of the extracted ...
