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…
Importance-Weighted Domain Adaptation for Sound Source Tracking
Bingxiang Zhong, Thomas Dietzen
In recent years, deep learning has significantly advanced sound source localization (SSL). However, training such models requires large labeled datasets, and real recordings are co…
Tracking of Spatially Dynamic Room Impulse Responses Along Locally Linearized Trajectories
Kathleen MacWilliam, Thomas Dietzen, Toon van Waterschoot
Measuring room impulse responses (RIRs) at multiple spatial points is a time-consuming task, while simulations require detailed knowledge of the room's acoustic environment. In pri…

Instantaneous PSD Estimation for Speech Enhancement based on Generalized Principal Components
Thomas Dietzen, Marc Moonen, Toon van Waterschoot
Power spectral density (PSD) estimates of various microphone signal components are essential to many speech enhancement procedures. As speech is highly non-nonstationary, performan…
Integrated sidelobe cancellation and linear prediction Kalman filter for joint multi-microphone speech dereverberation, interfering speech cancellation, and noise reduction
T. Dietzen, S. Doclo, M. Moonen +1
In multi-microphone speech enhancement, reverberation as well as additive noise and/or interfering speech are commonly suppressed by deconvolution and spatial filtering, e.g., usin…
Square root-based multi-source early PSD estimation and recursive RETF update in reverberant environments by means of the orthogonal Procrustes problem
T. Dietzen, S. Doclo, M. Moonen +1
Multi-channel short-time Fourier transform (STFT) domain-based processing of reverberant microphone signals commonly relies on power-spectral-density (PSD) estimates of early sourc…
