| summary | When a sound wave propagates from a point source through a medium and is reflected on surfaces before reaching microphones, the measured signals
consist of mixtures of the direct path signal with delayed and attenuated copies of itself. This acoustical phenomenon is referred to as echoes, or reverberation, and is generally considered as a nuisance in audio signal processing. After introducing some basic signal processing and acoustic background, this seminar will present recent works showing how acoustic echoes can be blindly estimated from audio recordings, and how the knowledge of such echoes can actually help some audio signal processing tasks such as beamforming, source separation or sound source localization. |
