Abstract
A system and method for joint acoustic echo control and adaptive array processing, comprising the decomposition of a captured sound field into N sub-sound fields, applying linear echo cancellation to each sub-sound field, selecting L sub-sound fields from the N sub-sound fields, performing L channel adaptive array processing utilizing the L selected sub-sound fields, and applying non-linear audio echo cancellation.
