Problems solved by technology

However, the sound-light linkage mode currently applied has several or more fixed effects. No matter what the song is, it is constantly repeated. Less investment but did not achieve the economic benefits brought by personalized and diverse stage lighting effects
[0005] Therefore, the defect in the prior art is that the existing lights change with the rhythm effect, no matter what the song is, the effect of the light changing with the rhythm is constantly repeated, and there is no different effect for different songs, so that the user experience is improved.

Embodiment 1

[0094] figure 1 It shows a flow chart of a lighting control method based on song accompaniment and microphone vocal real-time detection provided by an embodiment of the present invention; figure 1 As shown, Embodiment 1 provides a lighting control method based on real-time detection of song accompaniment and microphone vocals, including:

[0095] Step S1, obtaining the song accompaniment and microphone vocal signals in the song; it is particularly emphasized that the song accompaniment and microphone vocal are extracted from separate devices, because there is no original singing when singing.

[0096] Step S2, perform frequency sampling on the song accompaniment and microphone vocal signals according to the preset time sampling interval to obtain multiple sampling frequencies, and calculate the gain of multiple sampling frequencies, multiple sampling frequencies are composed of multiple low frequencies and multiple high frequencies composition;

[0097] Step S3, according to...

Embodiment 2

[0205] Based on the lighting control method based on song accompaniment and real-time detection of microphone vocals and the lighting control system 10 based on song accompaniment and microphone real-time detection in Embodiment 1, take the song "Death to Love" as an example and apply it to KTV For specific instructions on the lighting system of private rooms, see Figure 4 , in KTV's karaoke on-demand system and private room audio system (including microphones), the full-frequency detection of the accompanying sound and the full-frequency detection of the microphone's human voice are performed on the songs, and the classification of the four singing stages is obtained. Different songs have different classification results ;

[0206] Based on the lighting control method based on song accompaniment and real-time detection of human voice in Example 1 and the lighting control system 10 based on song accompaniment and microphone real-time detection of human voice, for the song "I ...

Embodiment 3

[0212] Based on the lighting control system 10 based on song accompaniment and real-time detection of microphone vocals in Embodiment 1, for different songs, according to the rhythm of different songs, different lighting effects are matched, but if the lighting and song rhythm cannot be uniformly controlled, It will affect the display effect of lighting and song rhythm coordination; therefore, for the unified control of lighting and song rhythm, the realization effect of the lighting control system 10 based on song accompaniment and microphone vocal real-time detection of the present invention can be better, such as with The lights are turned on and off by the rhythm of the music, or the flashing mode or rate is unified with the rhythm of the music, so that the dazzling effect of the unity of the music rhythm and the flashing rhythm of the lights cannot be achieved.

[0213] see Figure 16 , based on the above-mentioned unified control of song rhythm and lighting, the lighting c...

Abstract

The invention provides a light control method and system based on song accompanying sound and microphone voice real-time detection. The method includes the following steps: obtaining song accompanying sound and microphone voice signals in a song; conducting frequency sampling on the basis of a preset time sampling interval, and obtaining gains of multiple sampling frequencies; on the basis of gains of multiple low frequencies and gains of multiple high frequencies, performing rhythm classification judgment according to a first preset judgment condition, and obtaining low frequency rhythm points; performing rhythm classification judgment according to a second preset judgment condition, and obtaining high frequency rhythm points; on the basis of the low frequency rhythm points and the high frequency rhythm points, dividing the song into different singing stages according to a third preset judgment condition; and setting light for the song, and obtaining a song that has a light rhythm effect. For the melody rhythm characteristics of different songs, a song accompanying sound and microphone voice full-frequency detection technique and a real-time software analysis technique are adopted to judge different singing stages of the songs, and different light effects are utilized.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a lighting control method and system based on real-time detection of song accompaniment and microphone human voice. Background technique [0002] At present, the KTV system includes a karaoke on-demand system and a private room audio system. The karaoke on-demand system outputs accompaniment music (hereinafter referred to as the sound), and the sound system includes a special microphone device to pick up the voice of the singer (hereinafter referred to as the microphone voice), and the sound system and the microphone voice are sent to the speaker through the comprehensive processing of the sound system. sang the song. The number of current karaoke songs has reached more than one hundred thousand. [0003] In addition, the KTV system also includes the private room lighting system. In addition to the room lighting fixtures, various stage effect lamps are also becoming more and more...
