A personal audio system includes a processor to generate a personal audio stream by processing an ambient audio stream in accordance with an active processing parameter set, a circular buffer memory to store a most recent snippet of the ambient audio stream, and an event detector to detect a trigger event. In response to detection of the trigger event, a controller may transmit, to a knowledgebase remote from the personal audio system, the most recent snippet of the ambient audio stream and associated metadata."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processing sound using collective feedforward","description":"Personal audio systems and methods are disclosed.
