摘　　要：通过研究乐音的声音和物理特性,提出一种识别乐音信号的方法,该方法实现在频域的 精确定位,在基音频率检测上优于单一小波方法,在识别效果方面优于DTW方法,并开发了乐音识 别和自动作曲系统。此方法可以为乐音识别提供参考。This thesis investigate the musical and physical characters of the musical sound, and advances a new method to recognize the musical tone firstly. This method realizes the precise frequency resolution. It is more advantageous than the pitch detection method and the single wavelet method. It is also more effective than Dynamic Time Warping method. This method is ideal for the pitch recognition of the musical sound. It is first advanced in the technology domain and it has a high application value.
