SMP-PHAT: Lightweight DoA Estimation by Merging Microphone Pairs
François Grondin, Marc-Antoine Maheux, Jean-Samuel Lauzon +2
This paper introduces SMP-PHAT, which performs direction of arrival (DoA) of sound estimation with a microphone array by merging pairs of microphones that are parallel in space. Th…
BIRD: Big Impulse Response Dataset
François Grondin, Jean-Samuel Lauzon, Simon Michaud +2
This paper introduces BIRD, the Big Impulse Response Dataset. This open dataset consists of 100,000 multichannel room impulse responses (RIRs) generated from simulations using the…
Dynamic Object Tracking and Masking for Visual SLAM
Jonathan Vincent, Mathieu Labbé, Jean-Samuel Lauzon +3
In dynamic environments, performance of visual SLAM techniques can be impaired by visual features taken from moving objects. One solution is to identify those objects so that their…
3D Localization of a Sound Source Using Mobile Microphone Arrays Referenced by SLAM
Simon Michaud, Samuel Faucher, François Grondin +5
A microphone array can provide a mobile robot with the capability of localizing, tracking and separating distant sound sources in 2D, i.e., estimating their relative elevation and…
GEV Beamforming Supported by DOA-based Masks Generated on Pairs of Microphones
Francois Grondin, Jean-Samuel Lauzon, Jonathan Vincent +1
Distant speech processing is a challenging task, especially when dealing with the cocktail party effect. Sound source separation is thus often required as a preprocessing step prio…
