1 code implementation • 19 May 2020 • Francois Grondin, Jean-Samuel Lauzon, Jonathan Vincent, Francois Michaud

The solution presented in this paper is to train a neural network on pairs of microphones with different spacing and acoustic environmental conditions, and then use this network to estimate a time-frequency mask from all the pairs of microphones forming the array with an arbitrary shape.
