| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程技術研究所 === 86 === A study of the synthesis method the instrument-sound is presented in thisthesis. For the sake of simplicity, we only synthesize piano sound for example.For the signal processing unit, we adopt a sample playback synthesis method proposed by other researchers and slightly modify a time-domain processingtechnique, called "Time Proportionated Synthesis of Pitch Waveform. By using this technique, the pitch, the duration, and the volume almost can beindependently controlled. We do not need an additional envelop function, because we can figure out the curve by using interpolation techniques. Our synthesis method can simplify the implementation of the timbre file, by only recording the instrumenta1 sound and locating the pitch point. Therefore,we can improve the implemented speed and diminish the cost of the implementation.
