Existing game engines and virtual reality software, use various techniques to render spatial audio. One such technique, binaural synthesis, is achieved through the use of head-related transfer functions, in conjunction with artificial reverberators. For virtual environments that embody a large number of concurrent sound sources, binaural synthesis will be computationally costly. The work presented in this paper aims to develop a methodology that improves overall performance by culling inaudible and perceptually less prominent sound sources in order to reduce performance implications. The proposed algorithm is benchmarked and compared with distance-based, volumetric culling methodology. A subjective evaluation of the perceptual performance of the proposed algorithm for acoustic scenes having different compositions is also provided.

Perceptual audio source culling for virtual environments Metan, Ali Can; Hacıhabiboğlu, Hüseyin; Department of Modeling and Simulation (2016) Game engines and virtual environment software that are in use today, use various techniques to synthesize spatial audio. One such technique, is through the use of head related transfer functions, in conjunction with artificial reverberators. For any virtual environment, synthesizing large amounts of spatial audio through these methodologies, will impose a performance penalty for the underlying hardware. The aim of this study is to develop a methodology that improves overall performance by culling inaudible ...
Perceptual Soundfield Reconstruction in Three Dimensions via Sound Field Extrapolation Erdem, Ege; De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2019-05-01) Perceptual sound field reconstruction (PSR) is a spatial audio recording and reproduction method based on the application of stereophonic panning laws in microphone array design. PSR allows rendering a perceptually veridical and stable auditory perspective in the horizontal plane of the listener, and involves recording using nearcoincident microphone arrays. This paper extends the PSR concept to three dimensions using sound field extrapolation carried out in the spherical-harmonic domain. Sound field render...
Scattering delay network an interactive reverberator for computer games Enzo, De Sena; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2011-02-02) Many 3D computer games incorporate audio renderers simulating room acoustics to provide the user with a high level of immersiveness and realism. Full-scale interactive room auralisation systems are impractical for use in computer games due to their high computational cost. As a low-cost alternative, artificial reverberators can be used. This paper is concerned with the design of a scalable interactive reverberator inspired by digital waveguide mesh (DWM) models and feedback delay networks (FDN). This reverb...
Frequency Domain Scattering Delay Networks for Simulating Room Acoustics in Virtual Environments De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2011-11-28) Modelling, simulation and auralisation of room acoustics plays an important role in computer games and virtual reality applications by increasing the level of realism. Accurate simulation of room acoustics is a computationally costly process which is often substituted with artificial reverberators that provide a computationally simpler alternative. However, such systems lack the accuracy and are not in general able to accurately simulate important aspects of room acoustics such as early reflections, source/...
Immersive technologies in STEAM: A Metaverse User Experience Kaplan, Göknur (2022-09-11) This paper aims to explicate the perceptions and reflections of pre-service teachers, who designed and experienced an immersive 3D environment both in virtual reality and augmented reality modes. Twenty-four undergraduate students affiliated with various departments (science, mathematics, computer education) under the School of Education at Middle East Technical University (METU) in Ankara, Turkey participated in the study. Forty percent of the participants were males, where 60% were females with an age ran...
