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…
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…
Sound Field Translation and Mixed Source Model for Virtual Applications with Perceptual Validation
Lachlan Birnie, Thushara Abhayapala, Vladimir Tourbabin +1
Non-interactive and linear experiences like cinema film offer high quality surround sound audio to enhance immersion, however the listener's experience is usually fixed to a single…
