Abstract

The invention provides a song mode determining method, which comprises the steps of acquiring music score information of a song; acquiring the scale step in each mode; according to the scale step in each mode, determining natural notes in a note sequence corresponding to each mode of the song; according to the note sequence of the song and the duration of each note in the note sequence, determining the ratio of the natural notes in the note sequence corresponding to each mode of the song; and determining the mode corresponding to the maximum ratio of the natural notes as the mode of the song. The invention further provides a song mode determining device. The song mode determining method and the song mode determining device can determine the mode of the song according to the ratio of the natural notes in the note sequence of the song and correct the pitch according to the scale step in the corresponding mode; and the mode determining accuracy and the pitch correction accuracy are high.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a method for determining a song mode and a device for determining a song mode. Background technique [0002] In some existing karaoke software, there is an electronic sound effect. The function of this electronic sound effect is to detect the pitch of the song sung by the karaoke user. When the pitch level is on, the pitch is forced to be calibrated to the internal tone level corresponding to the mode of the song with the nearest principle. [0003] For example, if a song is in C major, the tone levels of the C major are C, D, E, F, G, A, B. When a karaoke user wants to sing the tone level E, but sings it in a ratio Level D# is slightly higher by 20 cents (that is, it is 80 cents lower than the tone level E), if the corresponding mode is not set, or the wrong mode is set, this will cause the pitch corrector to sang by the karaoke user An inaccurate sound level forces calibration...
