    摘要: Provided are a three-dimensional audio signal processing system using a rigid sphere and a method thereof. The three-dimensional audio signal processing system of the present research simplifies the shape of a human head into a rigid sphere, acquires three-dimensional audio signals by setting up mikes on the rigid sphere, and applies the acquire three-dimensional audio signals to diverse existing reproduction systems. The system includes a three-dimensional audio signal acquiring unit for acquiring audio signals by using a predetermined number of mikes set up on the rigid sphere; and a three-dimensional audio signal post-processing unit for converting the acquired audio signals to reproduce in diverse reproduction environments such as five-channel, four-channel, headphone, stereo, and stereo dipole reproduction environments.
