Abstract: We provide a Matlab GUI for the T-ABCD method for blind separation of convolutive mixtures of audio sources. The algorithm works in time-domain and is based on a complete unconstrained ICA decomposition of the observation space spanned by input signals. Almost arbitrary ICA method can be used. The method went through several modifications until the current version 2. Some functions have been removed, which simplifies the current GUI. The most important modification compared to version 1 consists in a new scale-invariant reconstruction of signals' images on the microphones. Hence, version 2 achieves significantly better signal-to-distortion ratio.
A complete SiSEC 2010 dataset for testing and benchmarks (task "Robust blind linear/non-linear separation of short two-sources-two-microphones recordings"): here
Instalation and execution of the T-ABCD package v2.0: Unzip the package into a directory, run Matlab, load microphone
recordings into rows of a matrix x,
and type (in Matlab)
