Abstract

The fruition of musical score by means of multimedia systems requires a suitable model for automatic or interactive expressive music performance. The authors present a method for controlling the mutable musical expressiveness in an abstract way, not necessarily working directly on the acoustic parameters. Our approach integrates symbolic and audio processing in a real-time networked environment. We present a mapping strategy allowing one to control and vary the expressiveness in a coherent way, by means of an abstract "control space". All the variations computed by the model on the symbolic representation are successively managed by the signal processing sub-system which coherently transforms the sound by a combination of different audio effects. The signal processing engine works in real time to render the desired expressive audio variations. The model is used interactively in a Web-based environment. The user controls the expressive character of the performance by moving within an appropriate control space.

乐谱互动表演的表现力变形

利用多媒体系统完成乐谱的制作，需要一种适合于自动或交互表现音乐的模型。作者提出了一种以抽象的方式控制可变音乐表现力的方法，而不一定直接对声学参数进行处理。我们的方法在实时网络环境中集成了符号和音频处理。我们提出了一种映射策略，允许人们通过抽象的“控制空间”以连贯的方式控制和改变表达性。由该模型计算出的所有符号表示上的变化依次由信号处理子系统进行处理，该子系统通过组合不同的音频效果对声音进行相干变换。信号处理引擎实时工作，以呈现所需的富有表现力的音频变化。该模型在基于web的环境中以交互方式使用。用户通过在适当的控制空间内移动来控制表演的表现力。
