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 rendering is performed using a two-level loudspeaker rig. An active-intensity-based analysis of the rendered sound field shows that the proposed approach can render direction of monochromatic plane waves accurately.

3D perceptual soundfield reconstruction via sound field extrapolation Erdem, Eg; Hacıhabiboğlui Hüseyin.; Department of Multimedia Informatics (2020) 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 thesis extends the two dimensional PSR concept to three dimensions and allows reconstructing an arbitrary sound field based on measurements with a...
Perceptual evaluation of a circularly symmetric microphone array for panoramic recording of audio Enzo, De Sena; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2010-05-06) A circularly symmetric multichannel audio recording and reproduction system has previously been proposed by Johnston and Lam [1]. This system aimed at perceptual reconstruction of the sound field and employed a sparse circular array of directional microphones driving a matching array of loudspeakers. An improvement to that system based on stereophonic time-intensity panning concepts has recently been proposed [2]. In this paper localisation performance of that system is compared with the original Johnston/L...
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 ...
SOUND SOURCE LOCALISATION PERFORMANCE OF OPEN SPHERICAL ACOUSTIC INTENSITY PROBES UNDER REVERBERANT CONDITIONS Hacıhabiboğlu, Hüseyin (2014-04-25) Open-spherical acoustic intensity probes are microphone arrays based on the Kirchhoff-Helmholtz integral and are used in the measurement of active acoustic intensity. The acoustic intensity measurements obtained by these arrays can be used to localise sound sources. Previously, the performance of these arrays in acoustic free field conditions were obtained using numerical simulations and it was shown that they provide better performance than other types of probes. This paper discusses the implementation of ...
PERCEPTUAL AUDIO SOURCE CULLING FOR VIRTUAL ENVIRONMENTS Metan, Ali Can; Hacıhabiboğlu, Hüseyin (2016-09-09) 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 perceptu...
