The input buffer stores sound data. The spatial filter generates processed data by using an internal adaptive control according to a control signal. The delay buffer stores the processed data. The controller operates in either one of a training stage, a flushing stage, or a normal stage and generates the control signal. When the controller operates in the training stage, the spatial filter receives the sound data from the input buffer to generate the processed data which is continuously processed by the spatial filter and then stored in the delay buffer over and over again until the internal adaptive control is converged."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and methods for reducing the processing time of the convergence of a spatial filter","description":"A noise-suppression device includes an input buffer, a spatial filter, a delay buffer, and a controller.
