Immersive and convincing acoustics in virtual reality applications require computationally highly efficient methods. Our fast and perceptually plausible room acoustics simulator RAZR [Wendt, T., van de Par, S., Ewert, S. D. (2014). "A computationally-efficient and perceptually-plausible algorithm for binaural room impulse response simulation," J. Audio Engineering Soc., vol. 62 (11), 748-766. DOI:10.17743/jaes.2014.0042 and Kirsch, C., Wendt, T., van de Par, S., Hu, H., and Ewert, S. D. (2023). "Computationally-Efficient Simulation of Late Reverberation for Inhomogeneous Boundary Conditions and Coupled Rooms," J. Audio Engineering Soc., vol. 71, 186-201. DOI:10.17743/jaes.2022.0053] approaches this demand by drastic simplifications with respect to physical accuracy, while focusing on human perception to achieve immersive and plausible simulations.

The current research version of RAZR is available here.
