基于振动频率识别的可视化音频简谱输出的设计与实现

Design and implementation of visual output based on tone vibration frequency recognition

分析了音频识别结合艺术创作应用的现状,指出本研究的重要性.介绍了音频分析和处理的关键技术,阐述了将音频转换为可视化简谱输出的方法,设计与实现了对振动频率的精确识别及可视化简谱的输出,解决了人们因为没有足够的乐理知识、时间、精力等,音乐创作受到限制的问题.提出的音频识别及转化输出方法,可应用于语音输入、多样化可视化显示等方面.

It is important to do this research because of the difficulties on the combination of audio recognition and artistic creation. The key technology of voice frequence analysis and process is introduced. A method of visual numbered musical notation output is proposed,and vibration frequency is recognized precisely in this method. It is a solution of musical creation limited by music theory,time,energy and so on. The method can be applied to many fields such as voice input and diversified visualization.
