The invention discloses a light display control method. The method comprises a step of data acquisition in which PCM waveform data of music are acquired, corresponding data are extracted from the PCMwaveform data and music data sections are generated, a step of spectrum generation in which each music data section is subjected to fast Fourier transform to generate a spectrum characteristic graph,and a step of first light adjustment in which the light display characteristics are acquired according to the spectrum characteristics in the spectrum characteristic graph to carry out corresponding adjustment on the light. The invention also discloses electronic equipment, a computer readable storage medium and a light display control device. The light display control method can more completely display the music spectrum characteristics through light changes, the change information such as the frequency and the loudness which can be sensed by a human ear can be displayed directly through thelight, and music visualization is thus realized.
