Direction-preserving Spatial Audio Signal Enhancement in The Spherical Harmonic Domain
Huawei Zhang, Jihui Aimee Zhang, Huiyuan June Sun +1
Spatial audio signal enhancement (SASE) aims to separate a desired soundfield from interference and noise while preserving its spatial cues. However, existing algorithms pay limite…
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…
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…
Past, Present, and Future of Spatial Audio and Room Acoustics
Shoichi Koyama, Enzo De Sena, Prasanga Samarasinghe +2
The study of spatial audio and room acoustics aims to create immersive audio experiences by modeling the physics and psychoacoustics of how sound behaves in space. In the long hist…
