Download Computer Synthesis Of Bird Songs And Calls
Bird songs are fascinating acoustic phenomena. In this paper, we first examine the acoustic mechanisms of sound production in birds and contrast them with their anatomy. Next, we describe the simulation of a one-mass source together with a simple transmission line model for a psittacine bird. In concluding, we discuss future areas for research.
Download Modeling Collision Sounds: Non-Linear Contact Force
A model for physically based synthesis of collision sounds is proposed. Attention is focused on the non-linear contact force, for which both analytical and experimental results are presented. Numerical implementation of the model is discussed, with regard to accuracy and efficiency issues. As an application, a physically based audio effect is presented.
