A Novel Method for Obtaining Diffuse Field Measurements for Microphone Calibration
Noman Akbar, Glenn Dickins, Mark R. P. Thomas +2
We propose a straightforward and cost-effective method to perform diffuse soundfield measurements for calibrating the magnitude response of a microphone array. Typically, such cali…
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…
An Efficient Parameterization of the Room Transfer Function
Prasanga Samarasinghe, Thushara Abhayapala, Mark Poletti +1
This paper proposes an efficient parameterization of the Room Transfer Function (RTF). Typically, the RTF rapidly varies with varying source and receiver positions, hence requires…
