Understanding the reverberation environment for immersive media
Philip Jackson, University of Surrey
Just as light and shading provide spatial information in an image, the way sound reflects and reverberates around an environment can be illuminating too. For example, from a room's response to an impulsive sound, it is possible to perceive the presence of nearby reflectors (such as a wall), the size of the room, whether the materials are hard or soft, and the approximate location of the sound source, including its distance. Hence reverb is among the most valuable tools in the sound designer's media production process for setting the scene, depth and perspective. In immersive media, the reverb takes on an additional spatial dimension. This talk presents recent audio, visual and audio-visual techniques to extract the information needed to reproduce the room impression spatially, with an emphasis on the kinds of acoustical processing and evaluation that may be less familiar. In concluding, various applications of the spatial reverb and future work will be discussed.
