Embodiment Construction

[0026] In the present invention, DSP techniques are used to estimate melody overtones from music signals. Here, melodic overtones are estimated instead of a single main melody. In melodic overtones, not only the fundamental frequency (ie, pitch) but also the harmonic structure are included. If only the pitch of the melody is estimated and matched, this is called estimating the main melody; while in the present invention, the pitch and harmonic structure are estimated simultaneously to express the melody information.

[0027] Furthermore, the melodic overtones and musical fragments of the searched piece are converted into a series of feature vectors. Searches for the correct piece of music by dynamically comparing feature vectors to determine if feature vectors match.

[0028] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like part...

Abstract

The invention discloses a method and a system which searches musical files based on waveform through humming musical rhythm, the method for searching the musical files which are based on the waveform through the humming musical rhythm comprises the following steps: inputting the musical files which are based on the waveform and inputting humming rhythm signals, dividing a singing section from theinput musical files based on the waveform, respectively estimating the rhythm overtone to the singing section and the humming rhythm signals, obtaining a masking musical note picture, carrying out the vectorization to the masking musical note picture of the singing section and the masking musical note picture of the humming musical rhythm signals to obtain the vector sequence of the singing section and the vector sequence of the humming rhythm signals, and comparing the vector sequence of the singing section and the vector sequence of the humming rhythm signals to confirm whether the singing section is matched with the humming rhythm signals.

Description

technical field [0001] The present invention relates to automatically searching for music, and more particularly, relates to a method and system for searching desired music files among a plurality of music files only by singing or humming the melody of the music, by which the user can quickly retrieve to the music you want to hear. Background technique [0002] Traditionally, when a user wishes to listen to music, he has to enter the name of the music, the artist's name, or other information related to the music to retrieve specific music in the music library. However, as the amount of music stored in the music library increases, it becomes more and more difficult for users to remember information related to such a large number of music, so that it becomes difficult to find music. [0003] To solve this problem, a content-based retrieval method named retrieval by humming (QBSH) was developed. The specific purpose of QBSH is to search for the desired music by inputting the ...
