Distributed Multichannel Wiener Filtering for Topology-Unconstrained Wireless Acoustic Sensor Networks
Paul Didier, Pourya Behmandpoor, Henri Gode +4
This paper introduces the topology-independent distributed multichannel Wiener filter (TI-dMWF), a novel algorithm for distributed node-specific signal estimation in wireless acous…
From General-Purpose Audio Tagging to Spatially Grounded Sound Event Localization and Detection
Stefano Giacomelli, Stefano Damiano, Claudia Rinaldi +2
This report investigates the extension of pretrained General-Purpose Audio Tagging (GP-AT) models toward spatially grounded Sound Event Localization and Detection (SELD). The propo…
HIDVAS: A Hearing Instrument Dataset in Various Acoustical Scenarios for Algorithm Evaluation and Training
Arnout Roebben, Giuliano Bernardi, Jan Wouters +2
To evaluate the performance of audio signal processing algorithms and to train data-driven algorithms, e.g., as applied in hearing instruments, either simulated or recorded data ca…
On the Use of Dereverberation for Acoustic Feedback Cancellation
Basil Liekens, Arnout Roebben, Toon van Waterschoot +1
In public address systems and hearing aids, the maximally achievable amplification or gain is limited by acoustic feedback. Therefore, in order to be able to apply a higher gain, f…
A state-space representation of the boundary integral equation for room acoustic modelling
Randall Ali, Thomas Dietzen, Matteo Scerbo +2
We introduce a new framework for room acoustics modelling based on a state-space model of the boundary integral equation representing the sound field in a room. Whereas state-space…
