應用串接方法於連續變化轉速之四行程引擎聲音合成 (Concatenation-based Method for the Synthesis of Engine Noise with Continuously Varying Speed) [In Chinese]

In this study, we propose and implement a concatenation-based audio signal synthesis system for the engine noises of continuously varying speed. A user simply draws the engine speed curve through an interface, and the corresponding audio signal is synthesized as output. This drawable interface makes the input function flexible and reduces the input time. The implemented system was evaluated with subjective tests. Overall, the performance was good regarding quality and similarity. The proposed method can be feasibly applied to the synthesis of any sound objects which are produced with a clear and simple physical process. Furthermore, the technology can be integrated to virtual reality, such as in training and gaming applications. keywords: audio object synthesis, concatenation synthesis method, engine noise synthesis, virtual reality 1 Proceedings of the Twenty-Fourth Conference on Computational Linguistics and Speech Processing (ROCLING 2012)
