Title:
オブジェクト・ベースのオーディオの仮想レンダリング
Document Type and Number:
Japanese Patent JP5897219
Kind Code:
B2
Abstract:
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 plurality of cross-talk cancelation circuits feeding a corresponding plurality of speaker pairs. 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.
