Visualization of Impulse Reponse of Virtual Accoustic Environments

Abstract

There are many methods that allow generate realistic 3D acoustic scenes. By means of new technologies it is possible to achieve a high level of realism. In many applications, the pictures are enhanced by sounds generated in 3D environment. This creates more realistic impression for the user. There are many methods that allow us to generate 3D sound and in such a way create high degree of reality in synthetic scenes. Nevertheless when generating sound in 3D environment, it is necessary to have relatively detailed information about the sound characteristics of the scene. Due to the complexity of this information it is necessary to visualize the sound distribution in the space where the sound will be generated. This paper describes a system of visualization of the impulse response of given acoustic environment whose development is one of our current research projects. We notice here its purpose, principles of implementation and basic applications.
