Problems solved by technology

And the method of mapping pitch and color gamut, timbre and saturation is not suitable for all situations. There are chords and harmony in most music, and in pop music and rock music, there is more track information, which is generally not suitable for all situations. It is impossible to distinguish which track is suitable for the real pitch, and it is not easy to distinguish the tone, so it also has shortcomings in the color control of the light

Embodiment 1

[0053] Such as figure 1 As shown, this embodiment provides a control method for lighting display, including the following steps:

[0054] S1: Obtain the PCM waveform data of the music, and extract the corresponding data from the PCM waveform data to generate music data segments. Further, the length of each music data segment is the same; by decoding the music file or reading the code stream of the audio input device Data, to obtain the PCM waveform data of the music;

[0055]S2: Perform fast Fourier transform on each music data segment to generate a spectrum feature map; then sequentially extract data from the PCM waveform data, and sequentially divide the audio data into data segments of the same size. Perform fast Fourier transform on each data segment to generate spectrum information;

[0056] S3: The light display characteristics are obtained according to the spectral characteristics in the spectral characteristic map, so as to adjust the light accordingly. The spectrum...

Embodiment 2

[0074] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, the light display control method of Embodiment 1 is realized. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.

Embodiment 3

[0076] Embodiment 3 discloses a readable computer storage medium, which is used to store a program, and when the program is executed by a processor, the light display control method of Embodiment 1 is realized.

Abstract

The invention discloses a light display control method, which comprises the following steps: data acquisition step: acquiring PCM waveform data of music, and extracting corresponding data from the PCM waveform data to generate music data segments; Fast Fourier transform is performed on the data segment to generate a spectrum feature map; the first light adjustment step: obtain the light display features according to the spectrum features in the spectrum feature map to adjust the light accordingly. The invention also discloses an electronic device, a computer-readable storage medium and a control device for light display. The light display control method of the present invention can more completely display music spectrum characteristics through light changes, so that change information such as frequency loudness that can be perceived by the human ear is directly displayed through light, thereby realizing music visualization.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a control method and device for lighting display. Background technique [0002] At present, there are many light bulbs on the market that support color and brightness adjustment, and people can change the lighting effect according to the needs of the scene. Many stage performances, concerts, KTV and indoor light shows require lighting effects to match music. [0003] At present, most stage lights still use manual pre-programming to realize the cooperation of music and lighting effects, which requires a lot of manpower and is inefficient. Ordinary indoor light shows are generally cyclical and repetitive effects, which cannot well fit the melody and rhythm of music playback. [0004] For color-changing light bulbs, the display parameters usually only have hue, saturation, and brightness. Generally, only the sound intensity can correspond to the brightness of the light in...
