Abstract
SummaryAn acoustic echo cancellation unit, comprising:an audio processor configured to receive a multichannel audio signal andcomprising:a first stage which is configured to process the multichannel audio signal to obtain a first set of spatial audio components; anda second stage which is configured to process the first set of spatial audio components to obtain a second set of spatial audio components;an echo cancellation processor configured to perform echo cancellation by use of the first set of spatial audio components or a deviated version of the first set of spatial audio components as reference signal.
