Auditory Localization in Low-Bitrate Compressed Ambisonic Scenes

Applied Sciences, 2019
The increasing popularity of Ambisonics as a spatial audio format for streaming services poses new challenges to existing audio coding techniques. Immersive audio delivered to mobile devices requires an efficient bitrate compression that does not affect ...

Low Frequency Sound Field Reproduction within a Cylindrical Cavity Using Higher Order Ambisonics [PDF]

Xibei Gongye Daxue Xuebao, 2018
Sound field reproduction of the aircraft and submarine within a cabin mock-up using a loudspeaker array is of great importance to the active noise control technology.The conventional method is to calculate the driving functions of the secondary sources ...

EigenScape: A Database of Spatial Acoustic Scene Recordings

Applied Sciences, 2017
The classification of acoustic scenes and events is an emerging area of research in the field of machine listening. Most of the research conducted so far uses spectral features extracted from monaural or stereophonic audio rather than spatial features ...

Comparison of 2D and 3D multichannel audio rendering methods for hearing research applications using technical and perceptual measures

Acta Acustica
Virtual reality with multichannel audio playback is increasingly used in hearing aid research. The purpose of this study is to compare horizontal (2D) and periphonic (3D) rendering methods in terms of localization, minimum audible angle, and perceptual ...

Static and moving minimum audible angle: Independent contributions of reverberation and position [PDF]

JASA Express Letters
Two measures of auditory spatial resolution, the minimum audible angle and the minimum audible movement angle, have been obtained in a simulated acoustic environment using Ambisonics sound field reproduction.

Denoising Directional Room Impulse Responses with Spatially Anisotropic Late Reverberation Tails

Applied Sciences, 2020
Directional room impulse responses (DRIR) measured with spherical microphone arrays (SMA) enable the reproduction of room reverberation effects on three-dimensional surround-sound systems (e.g., Higher-Order Ambisonics) through multichannel convolution ...

Residual Learning for Neural Ambisonics Encoders

CoRR
Emerging wearable devices such as smartglasses and extended reality headsets demand high-quality spatial audio capture from compact, head-worn microphone arrays. Ambisonics provides a device-agnostic spatial audio representation by mapping array signals to spherical harmonic (SH) coefficients. In practice, however, accurate encoding remains challenging.
