Embodiment 1

[0052] refer to figure 1 , shows a flow chart of the steps of the music retrieval method in Embodiment 1 of the present invention. It can be understood that the flowchart in this method embodiment is not used to limit the sequence of execution steps. The following uses the server as the execution subject to make an exemplary description. details as follows.

[0053] Step S100, pre-configuring an audio retrieval database, the audio retrieval database includes a plurality of piano window image data of a plurality of pre-stored audio.

[0054] Exemplary, see figure 2 , the step S100 may further include:

[0055]Step S1001, analyzing multiple spectrograms of multiple pre-stored audios.

[0056] Specifically, taking a pre-stored audio as an example, the pre-stored audio signal is converted into a spectrogram through Fourier transform, with the frequency value as the horizontal axis and the amplitude as the vertical axis. The conversion process is as follows:

[0057] The fu...

Embodiment 2

[0119] read on Figure 5 , shows a schematic diagram of program modules of Embodiment 2 of the music retrieval system of the present invention. In this embodiment, the music retrieval system 20 may include or be divided into one or more program modules, and one or more program modules are stored in a storage medium and executed by one or more processors to complete the present invention. Invention, and can realize the above music retrieval method. The program module referred to in the embodiment of the present invention refers to a series of computer program instruction segments capable of completing specific functions, which is more suitable for describing the execution process of the music retrieval system 20 in the storage medium than the program itself. The following description will specifically introduce the functions of each program module of the present embodiment:

[0120] Create a database module 200 for pre-configuring an audio retrieval database, the audio retrie...

Embodiment 3

[0173] refer to Figure 6 , is a schematic diagram of the hardware architecture of the computer device according to Embodiment 3 of the present invention. In this embodiment, the computer device 2 is a device capable of automatically performing numerical calculation and / or information processing according to preset or stored instructions. The computer device 2 may be a rack server, a blade server, a tower server or a cabinet server (including an independent server, or a server cluster composed of multiple servers) and the like. Such as Figure 6 As shown, the computer device 2 at least includes, but is not limited to, a memory 21 , a processor 22 , a network interface 23 , and a music retrieval system 20 that can communicate with each other through a system bus. in:

[0174] In this embodiment, the memory 21 includes at least one type of computer-readable storage medium, and the readable storage medium includes flash memory, hard disk, multimedia card, card-type memory (for...

Abstract

The embodiment of the invention provides a music retrieval method which comprises the following steps: configuring an audio retrieval database in advance, the audio retrieval database comprising a plurality of pieces of piano window image data of a plurality of pre-stored audios; analyzing a target spectrogram of the to-be-tested audio; calculating a target chrominance vector of the octave of theaudio to be measured according to the target spectrogram; generating corresponding target piano window image data according to the target chroma vector; calculating a cross correlation coefficient between the target piano window image data of the to-be-tested audio and the piano window image data of each pre-stored audio in the plurality of pre-stored audios to obtain a plurality of cross correlation coefficients; and selecting a target audio matched with the to-be-tested audio according to the plurality of cross correlation coefficients. The embodiments of the invention provide a music retrieval system, computer equipment and a storage medium. According to the embodiments of the invention, by calculating the cross correlation coefficient, the retrieval efficiency is improved, and the storage space is saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a music retrieval method, system, computer equipment and computer-readable storage medium. Background technique [0002] With the advent of the Internet age, big data has increasingly become a hot topic. In the field of music retrieval, facing millions of music data, how to achieve fast retrieval has become a very valuable problem. [0003] Most existing retrieval methods read waveform data from music and compare them with waveform data stored in a database to judge songs. However, the continuous accumulation of sound data in the database will lead to huge data volume, time-consuming retrieval and space-consuming. Contents of the invention [0004] In view of this, the purpose of the embodiment of the present invention is to provide a music retrieval method, system, computer equipment and computer-readable storage medium, by calculating t...
