SIREN: sound generation for vehicle simulation

Download

The ViP Simulator Sound Renderer (SIREN) software has been created as a means to facilitate generation and playback of audio signals in driving simulators. Siren is a modular, scalable program with a plug-in based infrastructure. The included plug-ins offer sound file playback, sound stream playback and spatialization possibilities. Required additional functionality can be added by creating custom plug-ins. Siren by default relies on the OpenAL library for spatialization and on Csound for sound stream generation. Other spatialization and generation software can be used by replacing the corresponding API modules. Siren is implemented in the new Simulator IV as well as in Simulator III at VTI and will also be implemented in Simulator II in the immediate future. Experimental implementations have been tested in the VTI Foerst simulator running solely under the Microsoft Windows operating system. Volvo Trucks has a trial version implemented in their simulator and has made some local customization. The current sound models implemented through Siren in the VTI simulators consist of real-time synthesis of sound based on measurements performed in real vehicles (car and truck) on the Volvo test track. The resulting sound has been validated through corresponding measurements performed inside the simulator cabins as well as through informal listening by experienced drivers.
