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…
RIR-Former: Coordinate-Guided Transformer for Continuous Reconstruction of Room Impulse Responses
Shaoheng Xu, Chunyi Sun, Jihui Zhang +2
Room impulse responses (RIRs) are essential for many acoustic signal processing tasks, yet measuring them densely across space is often impractical. In this work, we propose RIR-Fo…
Spatial Audio Signal Enhancement: A Multi-output MVDR Method in The Spherical Harmonic-domain
Huawei Zhang, Jihui Zhang, Huiyuan Sun +1
Spatial audio signal enhancement aims to reduce interfering source contributions while preserving the desired sound field with its spatial cues. Existing methods generally rely on…
