This abstract first appeared for US patent application 18476267 titled 'Method and System for Producing an Augmented Ambisonic Format
Original Abstract Submitted
A method that includes receiving audio content in a first-order ambisonics (FOA) format that includes a first plurality of audio signals, producing a plurality of spatially rendered audio signals by spatially rendering the first plurality of audio signals according to a layout of a virtual loudspeaker array, determining one or more filters by performing a parametric analysis upon at least one of the first plurality of audio signals, filtering at least one of the plurality of spatially rendered audio signals using the one or more filters; and producing a second plurality of audio signals in a higher-order ambisonics (HOA) format based on the plurality of spatially rendered audio signals.
