Embodiment Construction

[0071] In order to better illustrate the purpose and advantages of the present invention, the implementation of the method of the present invention will be further described in detail below in conjunction with examples.

[0072] The data resource that the present embodiment adopts is as follows: at first set up an audio storehouse that is made up of 1250 MP3 songs, including 555 songs of 132 male singers, size is 2.48GB, 695 songs of 116 female singers, size is 3.21GB, The song library contains songs in Chinese, English, Korean, Japanese and other types. First, the MP3 song is decoded into a WAV format voice file with mono, sampling rate 16kHz, and resolution 16bit, and then uses the average short-term energy based on the audio segment to filter the silent part of the song.

[0073] The overall steps of this embodiment are: select two songs of different singers from male and female singers, 4 songs in total. First use the system of the present invention to identify, then reco...

Abstract

The invention relates to a tone-similarity-based song retrieval method, aims at content-based music retrieval technology and provides a method of personal song modeling, calculation, retrieval, and matching based on MFCC (Mel frequency cepstrum coefficient) and GMM (Gaussian mixture model) and implementation of the method by comprehensively utilizing features such as song background music tone and voice characteristics of singers. Experimental results show that a system using the method is fast in retrieval, high in stability and highly expansible. The method is especially suitable for retrieval of audios with high requirement on tone, such as instrumental music audio retrieval systems and multimedia audio management systems.

Description

technical field [0001] The invention relates to a song retrieval method based on timbre similarity, and belongs to the technical field of multimedia information processing; specifically, it belongs to the technical field of audio processing. Background technique [0002] As an important media resource, music retrieval is of great significance to the construction of music databases and digital libraries. The amount of multimedia resources on the Internet is huge, and people need an efficient search engine to find the music resources they need from the vast amount of data. In addition, music retrieval has broad research prospects and great application value in karaoke retrieval and assisted video retrieval. Faced with the ever-increasing mass resources and people's high standards for music retrieval, the demand for music retrieval based on background music and singer's timbre is also increasing. The use of related technologies to realize the retrieval of similar music can no...
