Accurate reverberation algorithms are required for authentic experience in virtual or augmented reality experiences. A key element of immersive sound in virtual environments are the room acoustical modeling. Recent efficient and versatile algorithms has been proposed, namely the Scattering Delay Networks (SDN) and the Waveguide Web (WGW). This work presents the implementation of WGW in a current augmented reality application facilitating SDN reverberation. The application obtains informations about a given environment based on the positions of the sound source and listener. An evaluation is performed in a virtual environment to conclude a significant perceptual difference between WGW and SDN, with a significant preference to SDN over WGW. WGW is deemed too computational for real-time applications, but poses for a wide range of interesting possibilities for future work in the domain of acoustical modeling of outdoor spaces.
