The set of microphone signals represents the soundfield. The detected soundfield is decomposed into a set of sub-soundfield signals based on the set of microphone signals. Each sub-soundfield signal is processed, such that each sub-soundfield signal is separately dereverberated to remove reverberation therefrom, to produce a set of processed sub-soundfield signals. The set of processed sub-sound field signals are mixed into a mixed output signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Soundfield decomposition, reverberation reduction, and audio mixing of sub-soundfields at a video conference endpoint","description":"At a microphone array, a soundfield is detected to produce a set of microphone signals each from a corresponding microphone in the microphone array.
