Problems solved by technology

However, due to the lack of professional singing training for most ordinary users and the difference in the range of vocals that each person can sing, they often cannot complete the singing of the whole song well, even if the user guarantees that the rhythm is not wrong. Still have the problem of singing out of tune
There are some tuning methods in the prior art, by correcting the inaccurate pitch that the singer sings when singing, so that it can be adjusted to an accurate pitch, so that the song sung by the user is close to the original singing, but this method also has some flaws

Embodiment 1

[0041] See attached figure 1 , a flow chart of a method for correcting timbre in real time provided by an embodiment of the present invention, specifically comprising the following steps:

[0042] S101, the user sings with the standard rhythm of the song, and collects the singing voice when the user sings the song in real time;

[0043] The user sings at the standard rhythm of the song, which means that the user can keep up with the original accompaniment of the song, neither snapping nor slowing down. Correct the tone in real time.

[0044] S102. Extract the pitch of the user's singing voice, compare it with the standard pitch of the pre-stored song, and correct the user's singing voice according to the pitch difference;

[0045] Pitch, also known as pitch, expresses the subjective perception of the human ear on the pitch of a sound. Objectively speaking, the pitch mainly depends on the fundamental frequency of the sound wave. Higher frequency means higher pitch, and lower...

Embodiment 2

[0063] see figure 2 , an embodiment of the present invention provides a schematic structural diagram of a device for correcting timbre in real time, and the device is the subject of execution of the method for correcting timbre in real time described in Embodiment 1.

[0064] Specifically, see the attached figure 2 , the devices for real-time correction of timbre include:

[0065] Singing voice collection unit 1, when the user sings with the standard rhythm of the song, the singing voice when the user sings the song is collected in real time;

[0066] Pitch correction unit 2 extracts the pitch in the user's singing voice, compares it with the standard pitch of the song stored in advance, and corrects the user's singing voice according to the pitch difference;

[0067] The formant correction unit 3 extracts the formant of the user's singing voice after correcting the pitch, and reversely corrects the formant;

[0068] The singing voice beautification unit 4 stores fixed fo...

Embodiment 3

[0078] In order to realize the above method for modifying timbre in real time, an embodiment of the present invention further provides a hardware structure for a method for modifying timbre in real time. The hardware structure of the method for correcting timbre in real time in the embodiment of the present invention will be further described below, image 3 It is a schematic block diagram of a terminal device provided in an embodiment of the present application.

[0079] This embodiment provides a terminal device 100, such as image 3 As shown, the terminal device 100 includes: a memory 110 and a processor 120, the memory 110 stores a computer program, and the computer program is loaded and executed by the processor 120 to implement the step. Alternatively, the computer program is loaded and executed by the processor 120 to implement the functions of the units in Embodiment 2.

[0080] Wherein, the processor 120 may be one processor, or may be a general term for multiple p...

Abstract

The invention relates to the technical field of audio. The embodiment of the invention provides a method for correcting timbre in real time, which comprises the following steps of: performing singingby a user according to the standard rhythm of a song, and acquiring singing sound when the user sings the song in real time; extracting the pitch in the user's song, comparing the pitch with the pre-stored standard pitch of the song, and correcting the user's song according to the pitch difference; extracting a resonance peak value of the user song after pitch correction, and carrying out reversecorrection on the resonance peak value; and pre-storing the fixed formant parameters, performing weighting processing on the reversely corrected formant value of the user song and the pre-stored fixedformant parameters, and beautifying the user song. Through the technical scheme of the invention, the singing sound of the user can be corrected in real time. According to the technical scheme, the problem of singing tone shifting can be solved, it can be guaranteed that the tone of the corrected singing sound of the user is natural and listening, the corrected singing sound can be beautified, and the listening feeling of songs sung by the user is greatly improved.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a method, device, terminal equipment and computer storage medium for real-time correction of timbre. Background technique [0002] Singing is a kind of recreational activity that the public loves very much. People can choose to sing in KTV, or choose to show their singing voice through singing software such as Sing Bar and K Song Talent. The user generally sings along with the rhythm and lyrics on the subtitles when singing. However, due to the lack of professional singing training for most ordinary users and the difference in the range of vocals that each person can sing, they often cannot complete the entire song well. There is still the problem of singing out of tune. There are some tuning methods in the prior art, by correcting the inaccurate pitch that the singer sings when singing, so that it can be adjusted to an accurate pitch, so that the song sung by the user is close ...
