Abstract

The invention provides an audio retrieval method and device and electronic equipment, and the method can achieve the relatively independent extraction of the fingerprint features of each first audio clip in a target audio, and achieves the relatively independent updating of the matching degree count value of a second audio clip of a known audio based on the fingerprint features. And finally determining a known audio matched with the target audio according to the matching degree count value. Thus, under the condition that the number of the effective audio clips is enough, even if individual audio clips in the target audio are lost or disordered, the statistical result of the matching degree count value cannot be greatly influenced, the robustness of audio retrieval is improved, the calculation processing logic is simple, the retrieval processing speed is high, and the retrieval efficiency is improved. The streaming audio retrieval scene can be well adapted.

Description

technical field [0001] The present application relates to the technical field of audio and video data processing, and in particular, to an audio retrieval method, device and electronic equipment. Background technique [0002] Audio fingerprinting is a technique for retrieving target audio from known audio libraries. Usually, the search result includes the known audio retrieved based on the target audio and the position of the target audio in the known audio. Some existing audio fingerprint retrieval algorithms are usually designed for offline scenarios. In order to ensure the accuracy of retrieval, there are high requirements for the integrity and timing accuracy of audio data frames. However, in streaming audio and video scenarios, data may suffer from frame loss or out-of-sequence issues due to transmission delays, noise interference, and encoding loss. Moreover, for some streaming audio and video scenarios (such as live broadcast scenarios), there is a higher requiremen...
