Exploiting spatial information with the informed complex-valued spatial autoencoder for target speaker extraction
Annika Briegleb, Mhd Modar Halimeh, Walter Kellermann
In conventional multichannel audio signal enhancement, spatial and spectral filtering are often performed sequentially. In contrast, it has been shown that for neural spatial filte…
A Unifying View on Blind Source Separation of Convolutive Mixtures based on Independent Component Analysis
Andreas Brendel, Thomas Haubner, Walter Kellermann
In many daily-life scenarios, acoustic sources recorded in an enclosure can only be observed with other interfering sources. Hence, convolutive Blind Source Separation (BSS) is a c…
Joint Acoustic Echo Cancellation and Blind Source Extraction based on Independent Vector Extraction
Thomas Haubner, Zbyněk Koldovský, Walter Kellermann
We describe a joint acoustic echo cancellation (AEC) and blind source extraction (BSE) approach for multi-microphone acoustic frontends. The proposed algorithm blindly estimates AE…
Deep Learning-Based Joint Control of Acoustic Echo Cancellation, Beamforming and Postfiltering
Thomas Haubner, Walter Kellermann
We introduce a novel method for controlling the functionality of a hands-free speech communication device which comprises a model-based acoustic echo canceller (AEC), minimum varia…
Microphone Utility Estimation in Acoustic Sensor Networks using Single-Channel Signal Features
Michael Günther, Andreas Brendel, Walter Kellermann
In multichannel signal processing with distributed sensors, choosing the optimal subset of observed sensor signals to be exploited is crucial in order to maximize algorithmic perfo…
