Training Supports for the Japanese Classic Music by Audio Signal Processing.

日本在和平时期培育出来的一些成熟的艺术，将在西化和战后的混乱中逐渐消失，失去自己的身份。在独特的文化中，日本古典音乐面临着一种危机，很少有人欣赏它的价值。本研究试图通过对日本古典音乐音频信号处理的分析，为日本古典音乐的培训和教育提供一些支持方法。我们使用个人计算机修改了语音识别的计算机软件，分析了日本乐器的特征以及演奏者的水平分类：日本音乐有几个不同于西方音乐的特殊性，这可以用声谱图来表示。用A/D转换器以10微秒的采样率送入RAM板，在微机上进行谱密度分析。P之间的差异 ...更多信息 比较了演奏者对据说很难演奏的尺八音的能力。此外，还对日本古典音乐的电子键盘进行了检查，以与真实的尺八进行比较，这是通过彩色频谱图显示的。这些研究得出了一些结论，即在日本古典音乐中，声音更多地取决于演奏者个人，而不是西方同行，专家和初学者之间的差异可以通过颜色频谱图清楚地区分开来。另一项研究是利用X-Y跟踪器获取唇动信息，进行含嘴信息的语音识别。本研究可提供给羽球选手以支援系统，让他们能掌握挥颈姿势，而挥颈姿势的难度，就像需要三年的训练一样。最后，我希望有关方面能为所有的小学和/或初中提供教授日本音乐的机会。少

Some sophisticated Japanese arts, cultivated in a very long peace time, will fade away and lose its identity by westernization and the postwar disorders. Among the unique culture, the Japanese classic music have faced a danger, where very few people appreciate its value. Some great efforts are needed to prevent complete loss of our traditional music.This study has tried to provide some supporting methods for training and education of the Japanese classic music by analysis of audio signal processing. Modifying computer software for speech recognition using a personal computer, we analyzed characteristics of Japanese musical instruments together with the classifying players' levels : the Japanese music has several specific characters different from western music, which can be shown by spectrograms.Sounds continuously taken by an A/D converter with 10 micro second sampling rate into a RAM board are processed to make spectral density analysis in a personal computer. Differences among the p … More layers' abilities on the shakuhati sounds, which is said to be difficult to play, were compared. An electronic keyboard for Japanese classic music was also examined to make a comparison with a real shakuhati, that was shown by color spectrogram. These studies have lead to some conclusions that the differences between the experts and the beginners in Japanese classic music, where the sounds depends on the individual players more than the western counterparts, are clearly distinguished by the color spectrogram. And it was also shown that the music synthesizer can make similar sounds of the shakuhati.The other study was about the speech recognition with mouth information using an X-Y tracker which obtains lip movements. This study might help give supporting systems for the shakuhati players to get the positions for neck waving which is difficult as saying that it requires three year training. As a final remark, I would like the concerned to give chances for teaching Japanese music to all the elementary and/or the junior high schools. Less
