摘要: 本論文探討『物理模型聲音合成方式』與『實體半自動演奏系統』結合之可能性。目的是將實體半自動演奏系統在演奏時的各種物理參數,輸入進虛擬的聲音合成系統,並由實體的物理參數透過改良MIDI編碼意義來對應與控制虛擬聲音合成所需的參數,達到軟體與硬體配合的系統整合。其中選擇『運弓』與『敲擊』兩種演奏方式,作為本論文研究對象。對於聲音合成的部份,使用數位波導的聲音合成方式作為聲音合成之物理模型,並且加入各種數位濾波器來描述物理材料與運動之特性。而實作的部份,以步進馬達與壓電感測器、壓力感測器偵測實體演奏時的物理參數,並以Arduino為控制器作為軟硬體溝通平台,來實現軟硬體的物理參數對應。
This thesis examines the possibility of combining the “physical modeling based sound synthesis” and “semi-automatic playing system” and try to generate the variety of physical parameter by playing the semi-automatic playing system to correspond to the physical parameter of virtual sound synthesis system. In this thesis, choosing the “bow- ing” and “hammer” two kinds of ways as an experimental object. For the sound synthesis system part, using the digital waveguides method for the physical modeling and trying to add the variety of digital filter to simulate the physical material and motion model. For the semi-automatic playing system part, the sensor and stepper motor detect the physical parameter. Finally, achieve the system integration between software and hardware by using Arduino firmware system.
