The invention discloses a song searching method and device, equipment, a medium and a product. The method comprises the following steps: acquiring coding information corresponding to a to-be-searched song submitted by a client; adopting a feature extraction model trained to a convergence state to extract a high-dimensional index vector representing deep semantic information of multiple scales of the song to be searched according to the coding information; calculating the similarity between the high-dimensional index vector and a high-dimensional index vector which is extracted by the feature extraction model in a preset song feature library and represents multi-scale deep semantic information of each candidate song, and obtaining a similarity sequence; and screening and determining a target song of which the similarity value exceeds a preset threshold value and is the maximum similarity in the similarity sequence, constructing an access link corresponding to the target song, and pushing the access link to the client equipment. Through the above process, the service of searching for songs by songs can be quickly, efficiently and accurately realized, and the target songs similar to the to-be-searched songs can be searched for the user.
Description
technical field [0001] The present application relates to the technical field of music information retrieval, and in particular, to a song search method and its corresponding apparatus, computer equipment, computer-readable storage medium, and computer program product. Background technique [0002] With the popularity of short videos, live broadcasts, and radio stations, the amount of cover music is increasing, and the scenes that require music recognition are becoming more and more complex. Compared with the original version, the cover version may have differences or even completely different musical components such as timbre, fundamental frequency, rhythm, speed, harmony, lyrics, singing style, and overall structure. Therefore, cover recognition is a very challenging research work. [0003] There are a variety of technologies related to cover recognition in the prior art, and various prior technologies all have a certain degree of deficiencies, such as: (1) traditional La...
