基于音型数据库结构的多特征作曲系统设计

Design of multi-feature composition system based on figure database structure

为解决目前作曲系统存在作曲耗时长、匹配度低等问题,提出基于音型数据库结构的多特征作曲系统设计。首先,通过训练模块、作曲模块、数据库模块和用户界面模块完成对系统的总体框架设计,然后,通过处理器、存储卡、显示器、计算机和音响完成对作曲系统的硬件设计,最后,通过提取数据,对音型结构进行识别,再利用Matlab平台的函数和Java语言程序实现乐曲数据转换和输出,从而实现对作曲系统的软件设计,至此完成基于音型数据库结构的多特征作曲系统设计。实验结果表明,与传统的作曲系统相比,提出的多特征作曲系统的作曲耗时明显减少,匹配度可达到90%以上,表明提出的作曲系统具有更高的有效性。

A design of multi-feature composition system based on figure database structure is proposed to reduce the composition time-consumption and improve matching degree of the current composition system. The overall framework design of the system is completed by means of training module,composition module,database module and user interface module. The hardware design of the composition system is completed with the processor,memory card,display,computer and stereo. The figure structure is recognized by extracting data. The conversion and output of the music data are completed by means of the functions of the Matlab platform and the Java language program,so as to realize the software design of the composition system.The multi-feature composition system based on the figure database structure is completed. The experimental results show that,in comparison with the traditional composition system,the time-consumption of the proposed multi-feature composition system is significantly reduced,and its matching degree can reach more than 90%,which indicates that the proposed composing system has higher effectiveness.
