Title:

MULTI-ORDER OPTIMIZED AMBISONICS DECODING

Document Type and Number:

WIPO Patent Application WO/2024/059439

Kind Code:

A3

Abstract:

Ambisonics audio such as may be used for computer simulations such as computer games is improved by using multi-order optimizations that frame an optimization problem that minimizes a cost function (602) across a subset of Ambisonics orders for a chosen Ambisonics order "N". In a simple form, this cost function minimizes error across all orders (0 <= n <= N), and additional weighting (604) is applied to emphasize or de-emphasize particular orders. The cost functions and optimization criteria may be different for binaural and speaker outputs.
