Blind Capon Beamformer Based on Independent Component Extraction: Single-Parameter Algorithm,
Zbyněk Koldovský, Jaroslav Čmejla, Stephen O'Regan
We consider a phase-shift mixing model for linear sensor arrays in the context of blind source extraction. We derive a blind Capon beamformer that seeks the direction where the out…
Informed FastICA: Semi-Blind Minimum Variance Distortionless Beamformer
Zbyněk Koldovský, Jiří Málek, Jaroslav Čmejla +1
Non-Gaussianity-based Independent Vector Extraction leads to the famous one-unit FastICA/FastIVA algorithm when the likelihood function is optimized using an approximate Newton-Rap…
Target Speech Extraction: Independent Vector Extraction Guided by Supervised Speaker Identification
Jiri Malek, Jakub Jansky, Zbynek Koldovsky +3
This manuscript proposes a novel robust procedure for the extraction of a speaker of interest (SOI) from a mixture of audio sources. The estimation of the SOI is performed via inde…
Dynamic Independent Component/Vector Analysis: Time-Variant Linear Mixtures Separable by Time-Invariant Beamformers
Zbyněk Koldovský, Václav Kautský, Petr Tichavský
A novel extension of Independent Component and Independent Vector Analysis for blind extraction/separation of one or several sources from time-varying mixtures is proposed. The mix…
Adaptive blind audio source extraction supervised by dominant speaker identification using x-vectors
Jakub Janský, Jiří Málek, Jaroslav Čmejla +3
We propose a novel algorithm for adaptive blind audio source extraction. The proposed method is based on independent vector analysis and utilizes the auxiliary function optimizatio…
MIRaGe: Multichannel Database Of Room Impulse Responses Measured On High-Resolution Cube-Shaped Grid In Multiple Acoustic Conditions
Jaroslav Čmejla, Tomáš Kounovský, Sharon Gannot +2
We introduce a database of multi-channel recordings performed in an acoustic lab with adjustable reverberation time. The recordings provide information about room impulse responses…
