Optical-electronic Musical Instruments Based on Optical-electronic Controlling , MCU and Digital Signal Processing
Abstract:Considering the problems exisiting in current musical instruments, we present a optical-electronic musical instruments system based on optical-electronic controlling, MCU and digital signal processing, which mainly consists of optical-electronic controlling module, microprocessor-based data processing module, mediaplayer module, MIDI controlling module and voice-activated light-emitting module. Through controlling and detecting the laser net, the system realizes the playing of different pitch and tone. It also makes the EL module glow with the music. And on the basis of this, we use FFT which based on digital signal processing to analyse the constitution principle of pitch and tone. And it provides the data for the constitution principle of pitch and tone.
Keywords: optical-electronic controlling MCU digital signal processing EL controlling pitch and tone
