Abstract

The invention discloses a rhythm atmosphere lamp control method and system based on analog sound source sampling, and the method comprises the steps: obtaining an audio signal through an analog sound source, and carrying out the filtering and voltage regulation; resolving the audio signal into an amplitude on each frequency band by using fast Fourier transform; calculating a comprehensive amplitude by using a moving average method; the light signal resolving module determines a light mode according to the remote control signal and converts the amplitude into a light color signal and a brightness signal; performing non-linear gamma correction with offset on the luminance signal; and the corrected brightness signal and color signal are sent to an atmosphere lamp driving board, and the atmosphere lamp driving board lights up lamp beads according to the signals. According to the rhythm atmosphere lamp, the rhythm atmosphere lamp function based on simulated sound source sampling can be achieved, the application range of the rhythm atmosphere lamp is expanded, and good music and light experience is provided for a user.

Description

technical field

[0001] The invention relates to a rhythmic ambient light control method and system based on analog sound source sampling. Background technique

[0002] Music can soothe people's mood, and the ambient light that moves with the music can show the mood of the music

[0003] Most of the existing ambient light systems are monochrome ambient lights that cannot achieve lighting effects that follow the rhythm of the music. A small number of ambient lights with rhythm functions cannot be installed later because they rely on audio decoding chips, and they cannot use mobile phones or remote controls. Take control.

[0004] Therefore, how to make the ambient light system collect audio from the analog sound source and display different lighting effects with the change of music rhythm and amplitude, and realize the remote control function of the mobile phone / remote control system for the ambient light system has become an urgent technical problem to be solved. .
