On the Impact of Localization Errors on HRTF-based Robust Least-Squares Beamforming
Hendrik Barfuss, Walter Kellermann
In this work, a recently proposed Head-Related Transfer Function (HRTF)-based Robust Least-Squares Frequency-Invariant (RLSFI) beamformer design is analyzed with respect to its rob…
Towards a Generalization of Relative Transfer Functions to More Than One Source
Antoine Deleforge, Sharon Gannot, Walter Kellermann
We propose a natural way to generalize relative transfer functions (RTFs) to more than one source. We first prove that such a generalization is not possible using a single multicha…
Binaural coherent-to-diffuse-ratio estimation for dereverberation using an ITD model
Chengshi Zheng, Andreas Schwarz, Walter Kellermann +1
Most previously proposed dual-channel coherent-to-diffuse-ratio (CDR) estimators are based on a free-field model. When used for binaural signals, e.g., for dereverberation in binau…
Coherent-to-Diffuse Power Ratio Estimation for Dereverberation
Andreas Schwarz, Walter Kellermann
The estimation of the time- and frequency-dependent coherent-to-diffuse power ratio (CDR) from the measured spatial coherence between two omnidirectional microphones is investigate…
