In comparison to prior art virtual rendering utilizing a single pair of speakers, the described embodiments improve the spatial impression for both listeners inside and outside of the cross-talk canceller sweet spot. Also described is an improved equalization technique for a crosstalk canceller that is computed from both the crosstalk canceller filters and the binaural filters and applied to a monophonic audio signal being virtualized. The described techniques improve timbre for listeners outside of the sweet-spot as well as a smaller timbre shift when switching from standard rendering to virtual rendering."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual rendering of object-based audio","description":"Embodiments are described for a system for virtual rendering of object based audio through binaural rendering of each object followed by panning of the resulting stereo binaural signal between a plura","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9622011","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.
