The invention discloses a true color LED sound-light control apparatus and method thereof. The apparatus comprises: an audio frequency acquiring module for acquiring original audio frequency format and data; an amplitude frequency analyzing module for performs a Fourier transformation to the original audio frequency format and data provided by the audio frequency acquiring module and calculating the frequency and amplitude value at the same time; an effect generator module for generating the final true color LED data by combining the frequency and amplitude value from the amplitude frequency analyzing module and the effect generating mechanism of itself; a data sending module for sending the true color LED data generated by the effect generator module; and an effect previewing module for performing a two dimensional or three dimensional preview to the true color LED data generated by the effect generating module. The invention can provide a high efficient audio frequency acquiring by adopting modular design, provide a consistent interface for developing effect library thereby making it convenient for maintaining and utilizing the effect library.
Description
technical field [0001] The invention relates to a full-color LED technology, in particular to a full-color LED acousto-optic control device and method thereof. Background technique [0002] At present, there are many ways to control the sound and light of full-color LEDs: some are controlled by designing special circuits, such as DSP (Digital Signal Processing, Digital Signal Processing) and other chips, and some are controlled by using VFW (Video For Windows) on the PC platform. , camera window) to collect sound for data and effect processing. Although the above methods can be implemented, some circuits are more complex, and some have low efficiency in collecting sound, and the maintenance of the acousto-optic effect library is cumbersome, and there are certain limitations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a full-color LED acousto-optic control device and its method in order to overcome the defec...
