The at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to determine a non-overlapping virtual surface arrangement (400), the virtual surface arrangement (400) comprising a plurality of virtual surfaces (421, 423, 431, 433) with corners positioned at at least three speaker nodes of the plurality of speaker nodes (201, 203, 205, 207, 209) and sides connecting pairs of corners configured to be non-intersecting with at least one defined virtual plane within the three dimensional space. The apparatus is further caused to generate gains for the speaker nodes based on the determined the virtual surface arrangement and apply the gains to at least one audio signal, the at least one audio signal to be positioned within the three dimensional space."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spatial sound reproduction using multichannel loudspeaker systems","description":"An apparatus for spatial audio signal decoding associated with a plurality of speaker nodes (201, 203, 205, 207, 209) placed within a three dimensional space, the apparatus comprising at least one pro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11302339","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
