Methodology for 3D sound synthesis of directional acoustic sources by higher-order ambisonics

Autor: Thorner, Philippe, Bavu, Eric, Doc, Jean-Baptiste, Langrenne, Christophe

This paper presents the 3D soundfield synthesis of the pressure field radiated by directional acoustic sources using both the multimodal method and higher-order ambisonics (HOA). Ambisonics is a technique for encoding and reproducing measured or mode

Vibravox: A Dataset of French Speech Captured with Body-conduction Audio Sensors

Autor: Hauret, Julien, Olivier, Malo, Joubaud, Thomas, Langrenne, Christophe, Poirée, Sarah, Zimpfer, Véronique, Bavu, Éric

Vibravox is a dataset compliant with the General Data Protection Regulation (GDPR) containing audio recordings using five different body-conduction audio sensors : two in-ear microphones, two bone conduction vibration pickups and a laryngophone. The

Configurable EBEN: Extreme Bandwidth Extension Network to enhance body-conducted speech capture

Autor: Hauret, Julien, Joubaud, Thomas, Zimpfer, Véronique, Bavu, Éric

Publikováno v: IEEE/ACM Transactions on Audio, Speech, and Language Processing (2023 - Volume: 31) - pp. 3499 - 3512

This paper presents a configurable version of Extreme Bandwidth Extension Network (EBEN), a Generative Adversarial Network (GAN) designed to improve audio captured with body-conduction microphones. We show that although these microphones significantl

EBEN: Extreme bandwidth extension network applied to speech signals captured with noise-resilient body-conduction microphones

Autor: Hauret, Julien, Joubaud, Thomas, Zimpfer, Véronique, Bavu, Éric

Publikováno v: ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

In this paper, we present Extreme Bandwidth Extension Network (EBEN), a Generative Adversarial network (GAN) that enhances audio measured with body-conduction microphones. This type of capture equipment suppresses ambient noise at the expense of spee

BeamLearning: an end-to-end Deep Learning approach for the angular localization of sound sources using raw multichannel acoustic pressure data

Autor: Pujol, Hadrien, Bavu, Éric, Garcia, Alexandre

Publikováno v: J. Acoust. Soc. Am. 149 (6), June 2021

Sound sources localization using multichannel signal processing has been a subject of active research for decades. In recent years, the use of deep learning in audio signal processing has allowed to drastically improve performances for machine hearin

Rotationnal and translational waves in a bowed string

Autor: Bavu, Eric, Yew, Manfred, Placais, Pierre-Yves, Smith, John, Wolfe, Joe

We measure and compare the rotational and transverse velocity of a bowed string. When bowed by an experienced player, the torsional motion is phase-locked to the transverse waves, producing highly periodic motion. The spectrum of the torsional motion

Torsional waves in a bowed string

Autor: Bavu, Eric, Smith, John, Wolfe, Joe

Publikováno v: Acta Acustica united with Acustica 91, N2 (2005) 241

Bowing a string with a non-zero radius exerts a torque, which excites torsional waves. In general, torsional standing waves have higher fundamental frequencies than do transverse standing waves, and there is generally no harmonic relationship between
