- Abstract
The article proposes a design scheme of LED light music rhythm based on virtual instrument, studying the audio signal collection, processing and application. Instead of a general data collection card, using computer sound card as hardware acquisition audio signal and transmit it to the computer. On the LabVIEW software platform, based on signal processing function, audio playback and signal processing system is designed, which analysis and process the audio signal at different frequencies of input signal strength to generate the output signal associated with the frequency and intensity of the input audio signal, so that realizes the LabVIEW virtual LED matrix in the program and the actual LED matrix real-time synchronously to flicker with the rhythm of the music. The design of the audio signal acquisition and processing system is provided with good human-machine interface, strong real-time performance and convenient operation. It can be extended its function according to the needs of user. With broad application prospect, it can be applied to a variety of audio signal collection and processing fields such as speech recognition, environmental noise monitoring, etc.
