THREE-DIMENSIONAL AUDIO SIGNAL PROCESSING APPARATUS AND METHOD Russian patent published in 2025 - IPC G10L19/08 G10L25/27 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering for processing audio data. Determining the encoding or decoding mode of the current frame based on the sound field classification result comprises: when the sound field classification result contains the number of heterogeneous sound sources or the sound field classification result contains the number of heterogeneous sound sources and the type of the sound field, determining the encoding or decoding mode of the current frame based on the number of heterogeneous audio sources; when the sound field classification result contains the sound field type or the sound field classification result contains the number of heterogeneous sound sources and the sound field type, determining the encoding or decoding mode of the current frame based on the sound field type; or, when the result of classifying the sound field contains the number of heterogeneous sound sources and the type of the sound field, determining the encoding or decoding mode of the current frame based on the number of heterogeneous sound sources and the type of the sound field.

EFFECT: high accuracy of identifying a three-dimensional audio signal.
