Abstract:
In Audio-only games,the players can only control the game process and operation based on the orientation information of the sound source in three dimensional virtual sound space,and so real time processing with high accuracy is needed in sound reconstruction. In the paper,based on the basic principle of the HRTF-based three dimensional virtual sounds,the individualized matching and compression method was analyzed and validated through the process progress of the CIPIC and MIT HRTF data using PCA method. The small error between the original and the compress-reconstruct HRTF data proved that the proposed method can be applied in real-time processing system with less storage space and simplified computational complexity to enhance the reconstruction speed and accuracy,which is favorable for the practical application of virtual sound.
