Sparse Recovery of Acoustic Waves

ICASSP 2022accepted

We present a general model for acoustic wave decomposition (AWD) on a rigid surface for a general microphone array configuration. The decomposition is modeled as a sparse recovery optimization problem that is independent of the shape of the rigid surface or the microphone array geometry. We describe…

Asynchronous Acoustic Echo Cancellation Over Wireless Channels

Robert Ayrapetian, Philip Hilmes, Mohamed Mansour, Trausti Kristjansson, Carlo Murgia

ICASSP 2021accepted

We introduce a novel acoustic echo cancellation framework for systems where the loudspeaker and the microphone array are not synchronized. We consider the problem in the most general form where the loss of synchronization is time-varying. The proposed system is linear and it utilizes microphone arra…
