Embodiment 1

[0056] figure 1 It is a flowchart of a method for identifying the climax part of a song according to an embodiment of the present invention, combined below figure 1 To describe the method for identifying the climax part of a song according to an embodiment of the present invention, the method can be applied to portable mobile terminals such as mobile phones and tablet computers, and can also be applied to computers, such as figure 1 As shown, the method includes the following steps:

[0057] S10. Extracting the sound intensity data of the song selected by the user;

[0058] S20. Select at least one sound intensity peak value according to the sound intensity data;

[0059] S30. Calculate the difference between at least one sound intensity peak value and the sound intensity value at the time point at the left end of at least one sound intensity peak value;

[0060] S40. Determine the start time of the climax part of the corresponding song according to the difference.

[0061...

Embodiment 2

[0068] For a more concise description, this embodiment only describes the relevant parts of this embodiment on the basis of including the first embodiment above.

[0069] The time point at the left end of the at least one sound intensity peak is determined by the time point at which the at least one sound intensity peak is located and a preset time step.

[0070] According to an example of this embodiment, the specific method for calculating the start time of the climax part includes:

[0071] Obtain the time point t where the at least one sound intensity peak is located 1 , t 2 , t 3 ,...,t n ;

[0072] Select the time point t at the left end of the at least one sound intensity peak 1 -s, t 2 -s, t 3 -s,...,t n -s;

[0073] Calculate the absolute value d of the difference between the sound intensity data value at each left end time point and the corresponding sound intensity peak value 11 、d 21 、d 31 ,...,d n1 ;

[0074] judge 11 ~ d n1 Whether the maximum val...

Embodiment 3

[0080] figure 2 It is a flowchart of a method including identifying the end time of the climax part of a song according to an embodiment of the present invention, such as figure 2 As shown, on the basis of including the above steps S10, S20, S30, S40, the method also includes:

[0081] S50. Calculate the difference between the sound intensity value of at least one sound intensity peak and the time point at the right end of at least one sound intensity peak, the time point at the right end of at least one sound intensity peak is the time point where at least one sound intensity peak is located and the preset time to determine the step size;

[0082] S60. Calculate the end time of the climax part according to the difference between the value at the time point at the right end and at least one maximum value of the sound intensity peak value.

[0083] According to an example of this embodiment, the specific method for calculating the end time of the climax part includes:

Abstract

The invention discloses a mobile terminal and a method and device for identifying the chorus part of a song thereof and belongs to the technical field of mobile terminals. The method comprises the steps of extracting the sound intensity data of the song selected by a user, selecting at least one sound intensity peak value according to the sound intensity data, calculating the difference value between the at least one sound intensity peak value and the sound intensity value of a time point at the left end of the at least one sound intensity peak value, and determining the initial time of the chorus part of the corresponding song according to the difference value. According to the method and device for identifying the chorus part of the song, the chorus part of the song is identified according to the sound intensity data, such as data intensity and sound frequency, of the song, and the application range is wide; when the method is used for audition of songs and musical compositions, a user can be helped in finding the chorus part of the song quickly and does need to listen from the prelude of the song; when the method is used for making music ringtones, a user can be helped in finding the part, suitable for serving as a ringtone, of the song quickly, and time is saved for the user.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile terminal and a method and device for identifying the climax part of a song. Background technique [0002] Many music players provide the function of browsing and listening to songs, so that users can find their favorite songs when they can't remember the title of the song. In addition, some companies provide a paid download function for high-quality songs. Before downloading, users hope to listen to a certain segment of the song to prevent downloading the wrong song because of the same name of the song. [0003] However, the beginning part of the general song is relatively flat, or there is only background sound, and the user cannot hear the essence of the song, making it difficult for the user to quickly find the song they want to listen to, or it takes a long time to hear the singer's voice. The experience is rather bad. [0004] Most of the methods used in ...
