Problems solved by technology

However, since a file is modified, its MD5 code will also change accordingly. This method cannot effectively identify music files with the same music but different compression ratios, because the MD5 codes of the two are different.
Therefore, this music information retrieval method based on MD5 codes has certain limitations, and it is also cumbersome to use.

Embodiment Construction

[0015] In order to have a more specific understanding of the technical content, characteristics and effects of the present invention, now in conjunction with the illustrated embodiment, the details are as follows:

[0016] Audio fingerprints are content-based compact digital signatures that can represent important acoustic features of a piece of music. Audio fingerprint technology usually includes two parts: a fingerprint extraction algorithm that calculates important auditory features and a fingerprint comparison algorithm that searches effectively in the fingerprint database. When identifying an unknown piece of audio, first calculate its audio features according to the fingerprint extraction algorithm, and then compare it with a large number of audio fingerprints stored in the fingerprint database according to the fingerprint comparison algorithm to identify the corresponding audio. An effective audio fingerprinting technique is able to correctly identify the original versi...

Abstract

The invention discloses a method for recovering local music information based on audio fingerprinting technology. The method comprises the following steps of: firstly, creating a music database on a server side, wherein the music database takes audio fingerprints as the indexes of corresponding music information; inputting, by a user at a client, a local path of music files which are needed to be supplemented with missing information; extracting, by the client, the audio fingerprints of the music files in the path, and transmitting the audio fingerprints obtained to the server side; performing comparison lookup in the music database by the server side, and transmitting the information of music corresponding to the audio fingerprints to the client; and after the client obtains the missing information, providing the missing information for the user to look over, or directly modifying the music files, or rearranging the music files. With the method of the invention, the user can conveniently re-obtain various kinds of missing information of the local music files; and the method is not only simple and quick, but also accurate.

Description

technical field [0001] The invention relates to a method for regaining information missing from local music, in particular to a method for recovering local music information based on audio fingerprint technology. Background technique [0002] In the process of using the computer, the computer user's local machine may store many music files, such as MP3, CD, etc., and the information of these music files (such as song name, artist name, album name, album publishing year, album cover, etc.) may It is incomplete at first, and may not be found or lost as time goes by. If computer users want to regain the missing information of these music files, a currently known method is the music information recovery method based on MD5 codes , MD5 code is the abbreviation of message-digest algorithm 5 (information-digest algorithm), it can be said to be the "digital fingerprint" of the file, any file, whether it is an executable program, image file, temporary file or any other type of file ...
