AURALIZ_RT is an application and method for performing interactive auralizations using real-time sound sources. Auralization enables the experience of immersive acoustic environments through computer-models of physical space. Provided auditory sensory input derived through prediction of sound transmission, the spatial characteristics can be altered and perceptually compared. With the application the audience interacts with the space by generating sound through action, enabling a direct experience of the acoustical response.

The proposed method is based on a reversed argument for altered voice, tapping into conscious or unconscious processes as such defined by Étienne Lombard, however extended to incorporate further acts of alteration as a reaction from the acoustical sensory input.

Project was initiated in collaboration with Chalmers University of Technology, Gothenburg and Tyréns, Stockholm, Sweden, during 2011.

Application is implemented in the open source  programming-environment Pure data and utilizes room impulse responses (RIRs) obtained through acoustical prediction software.

Patch will soon be made available on Github for download.
