An Efficient Parametric Codec for Low-Bitrate First-Order Ambisonics
Wei-Ting Lai, Amy Bastine, Lachlan Birnie +2
Driven by the rapid growth of immersive teleconferencing and generative spatial audio, efficient low-bitrate coding of first-order Ambisonics (FOA) has become increasingly importan…
PathRIR: Physics-Guided Acoustic Path Selection and Late-Tail Compensation for Fast Room Impulse Response Simulation
Shaoheng Xu, Chunyi Sun, Jihui Zhang +3
Image-source-method (ISM)-based room impulse response (RIR) simulation is a useful and physically interpretable tool for acoustic scene modeling, but full-order ISM becomes computa…
HRIR-Former: Grid-Free Time-Domain Reconstruction of Head-Related Impulse Responses with a Spatially Encoded Transformer
Shaoheng Xu, Chunyi Sun, Jihui Zhang +4
Individualized head-related impulse responses (HRIRs) enable binaural rendering, but dense per-listener measurements are costly. We address HRIR spatial up-sampling from sparse per…
Source Localization by Multidimensional Steered Response Power Mapping with Sparse Bayesian Learning
Wei-Ting Lai, Lachlan Birnie, Xingyu Chen +3
We propose an advance Steered Response Power (SRP) method for localizing multiple sources. While conventional SRP performs well in adverse conditions, it remains to struggle in sce…
A Two-Step Approach for Narrowband Source Localization in Reverberant Rooms
Wei-Ting Lai, Lachlan Birnie, Thushara Abhayapala +3
This paper presents a two-step approach for narrowband source localization within reverberant rooms. The first step involves dereverberation by modeling the homogeneous component o…
An Active Noise Control System Based on Soundfield Interpolation Using a Physics-informed Neural Network
Yile Angela Zhang, Fei Ma, Thushara Abhayapala +2
Conventional multiple-point active noise control (ANC) systems require placing error microphones within the region of interest (ROI), inconveniencing users. This paper designs a fe…
Head-Related Transfer Function Interpolation with a Spherical CNN
Xingyu Chen, Fei Ma, Yile Zhang +2
Head-related transfer functions (HRTFs) are crucial for spatial soundfield reproduction in virtual reality applications. However, obtaining personalized, high-resolution HRTFs is a…
Sound Field Estimation around a Rigid Sphere with Physics-informed Neural Network
Xingyu Chen, Fei Ma, Amy Bastine +2
Accurate estimation of the sound field around a rigid sphere necessitates adequate sampling on the sphere, which may not always be possible. To overcome this challenge, this paper…
