一种二胡音乐的WAVE转MIDI的设计方法
A Design Method for Converting Erhu Music from WAVE to MIDI
摘要
Abstract
Mainly introduced the specific design process of converting an erhu mine file from WAVE to MIDI. Firstly .abstract the fundamental frequency of the notes by means of DWT and FFT analysis. Seccndly.transfonn the fundamental fnquency Id MIDI notes on the bans of specific message format of MIDI files. Thirdly,set specified dual-threshold according to the properties of emu to screen valid notes,and finally compote them with other control information to form MIDI files. Experiments show mat the method owns a higher pitch extraction accuracy for the erhu mask .and can generate the required effective MIDI file.关键词
