Sound Source Localization in Spherical Harmonics Domain Based on High-Order Ambisonics Signals Enhancement Neural Network

IEEE Access
Compared with methods based on microphone arrays, sound source localization methods based on higher-order ambisonics (HOA) signals are no longer limited to specific array structures and exhibit better performance in multi-source scenarios.

Ambisonics Networks - The Effect of Radial Functions Regularization [PDF]

ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Ambisonics, a popular format of spatial audio, is the spherical harmonic (SH) representation of the plane wave density function of a sound field. Many algorithms operate in the SH domain and utilize the Ambisonics as their input signal. The process of encoding Ambisonics from a spherical microphone array involves dividing by the radial functions, which

Binaural Auralization of Room Acoustics with a Highly Scalable Wave-Based Acoustics Simulation

Applied Sciences, 2023
This paper presents a proposal of an efficient binaural room-acoustics auralization method, an essential goal of room-acoustics modeling. The method uses a massively parallel wave-based room-acoustics solver based on a dispersion-optimized explicit time ...

Sonic colonialities: Listening, dispossession, and the (re)making of Anglo‐European nature

Transactions of the Institute of British Geographers, Volume 48, Issue 4, Page 690-702, December 2023., 2023
Abstract Creative and feminist geographers position listening as a way to build more responsive, ethical, and reciprocal relations to people and environments. In this paper I argue that for geographers to situate listening – in the broadest definition as ‘sensing, attuning, and noticing’ – as part of a creative approach to reparative practice, we must ...

Multisource localization based on angle distribution of time–frequency points using an FOA microphone

CAAI Transactions on Intelligence Technology, Volume 8, Issue 3, Page 807-823, September 2023., 2023
Abstract Multisource localization occupies an important position in the field of acoustic signal processing and is widely applied in scenarios, such as human‐machine interaction and spatial acoustic parameter acquisition. The direction‐of‐arrival (DOA) of a sound source is convenient to render spatial sound in the audio metaverse.
