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 ...

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.

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 ...

Projetando o espectro do som no espaço: imagens-movimento de parciais e grãos sonoros

Orfeu, 2020
Enquanto o tempo é sempre mencionado como característica inerente à música, o espaço na maioria das vezes não é tratado como categoria operatória da composição, algo que mudou de figura durante o século XX devido a novas abordagens composicionais e ...

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.

Eigenbeam–vMF-Based Room Acoustic Analyzer: A Comparative Study with First-Order and Higher-Order Ambisonic Recordings

Applied Sciences
Comprehensive room acoustic characterization requires resolving reflection behavior across time, frequency, and space. The recently proposed eigenbeam–vMF-based analyzer provides a framework for this by modeling the reflection field as a time–frequency ...

Recording, Processing, and Reproduction of Vibrations Produced by Impact Noise Sources in Buildings

Acoustics
Several studies on the perception of impact sounds question the correlation of standardized approaches with perceived annoyance, while more recent studies have come to inconsistent conclusions.
