Multi-Source DOA Estimation through Pattern Recognition of the Modal Coherence of a Reverberant Soundfield
A. Fahim, P. N. Samarasinghe, T. D. Abhayapala
We propose a novel multi-source direction of arrival (DOA) estimation technique using a convolutional neural network algorithm which learns the modal coherence patterns of an incid…
PSD Estimation and Source Separation in a Noisy Reverberant Environment using a Spherical Microphone Array
Abdullah Fahim, Prasanga N. Samarasinghe, Thushara D. Abhayapala
In this paper, we propose an efficient technique for estimating individual power spectral density (PSD) components, i.e., PSD of each desired sound source as well as of noise and r…
PSD Estimation of Multiple Sound Sources in a Reverberant Room Using a Spherical Microphone Array
Abdullah Fahim, Prasanga N. Samarasinghe, Thushara D. Abhayapala
We propose an efficient method to estimate source power spectral densities (PSDs) in a multi-source reverberant environment using a spherical microphone array. The proposed method…
