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.
