The sound system has at least two loudspeakers of a basic system and at least three loudspeakers of a focus system, each of the loudspeakers having a position in an environment. The apparatus has a basic channel provider for providing basic system audio channels to drive the loudspeakers of the basic system, and a focused source renderer for providing focus system audio channels to drive the loudspeakers of the focus system. The focused source renderer is configured to calculate a plurality of delay values for the loudspeakers of the focus system based on the positions of the loudspeakers of the focus system and based on a position of a focus point, and to generate at least three focus group audio channels for at least some of the loudspeakers of the focus system based on the plurality of delay values and based on a focus audio base signal to provide the focus system audio channels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for creating proximity sound effects in audio systems","description":"An apparatus for driving loudspeakers of a sound system is provided.
