Embodiment Construction

[0037] The present invention and its advantages will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, and have no limiting effect on it.

[0038] The present invention mainly studies content-based music retrieval (Content based Music Retrieval), and provides a way to search for music by using the music itself. Specifically, a short piece of music melody is used as a search keyword, and the search engine returns a group of music that contains the specified key melody. The melody is used as a keyword, which is different from the text keyword. The user cannot input directly from the keyboard, but needs to provide a special method for inputting the melody. The method most in line with people's habits is humming input. The user only needs to use an audio acquisition input device, such as a microphone, to hum a melody that needs to be...

Abstract

The present invention discloses a digital music search method and a device therefore, which can search the music with the designated melody by taking musical melody as the keyword. The present invention provides two melody input methods to a user: playing and humming. The humming input method adopts a series of signal processing methods to analyze the humming audio signal and extract the melodic information. A musical database adopts a reverse algorithm to compile an index, thus increasing the search efficiency. The device provided by the present invention is divided into a server terminal and a client terminal; the server terminal is to maintain the musical database and the index thereof and responds the search query of the client terminal; the client terminal is to collect the melodic input of the user, receive and display the search result of the server. The present invention utilizes the musical melody to search the music, thus compensating the shortcoming of the traditional text-based search method and helping the user to search the wanted music without text information. The user can use computers, mobile phones and other common equipment for music search.

Description

technical field [0001] The invention belongs to the application field of computer technology, and in particular relates to a retrieval method for digital music using melody as a keyword, as well as computer hardware and communication equipment that enable the method to run smoothly. Background technique [0002] With the exponential growth of the amount of Internet information, how to quickly and accurately find the information we need from the massive information database has become a major bottleneck for people to use the Internet. Content-based multimedia retrieval is an emerging research field, which provides people with a new way of searching: using multimedia itself to search multimedia information. Multimedia information has various forms such as audio, video, image, and animation, among which audio information occupies a considerable proportion. Among audio, music is the most common form. The current music search is mainly based on text keywords, such as music name...
