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…
