摘要
为了构建虚拟乐器,提出了一种可控音色模型。该模型包括频谱子模型和振幅包络子模型。保持振幅包络子模型参数不变,调节频谱子模型参数,对音色效果进行分析,找到这些参数对乐器音色的作用规律。分析和实验表明,该模型可提供对音量、衰减快慢、泛音宽度和泛音位置等方面的控制。与以往硬件合成音色的方法相比,该软件方法可节省大量的成本,同时实现音色的可控性。对软件乐器音色的构建和算法作曲具有一定的理论价值和基础意义。
A controllable timbre model was presented, in order to construct virtual musical instrument. Two sub models, the frequency spectrum model and the amplitude envelope model, were included in this model. The timbre effect was analyzed by modulating the parameters of frequency spectrum model, on condition that the parameter values of amplitude envelope model was invariable. Thus the rules of the parameters acting on the instrument timbre were found. The analyses and experiments show that this model can control the volume, the attenuation speed, the overtone width, and the overtone location. Compared with the method by hardware timbre - commpose, this software method can economize costs greatly and can make the timbre controllable. So it is of important theoretical value and fundamental significance for the timbre construction of software musical instrument and for the algorithm music composition.
