US 2023/0412981 A1 · METHOD AND APPARATUS FOR DETERMINING VIRTUAL SPEAKER SET

Abstract

This application provides a method and an apparatus for determining a virtual speaker set. The method for determining a virtual speaker set includes: determining a target virtual speaker from F preset virtual speakers based on a to-be-processed audio signal, where each of the F virtual speakers corresponds to S virtual speakers, F is a positive integer, and S is a positive integer greater than 1; and obtaining, from a preset virtual speaker distribution table, respective position information of S virtual speakers corresponding to the target virtual speaker, where the virtual speaker distribution table includes position information of K virtual speakers, the position information includes an elevation angle index and an azimuth angle index, K is a positive integer greater than 1, F≤K, and F×S≥K. This application can improve audio signal playback effect.

A method for determining a virtual speaker set, comprising:

determining a target virtual speaker from F preset virtual speakers based on a to-be-processed audio signal, wherein each of the F preset virtual speakers corresponds to S virtual speakers, wherein F is a positive integer, and wherein S is a positive integer greater than 1;
and
obtaining, from a preset virtual speaker distribution table, respective position information of S virtual speakers corresponding to the target virtual speaker, wherein the virtual speaker distribution table comprises position information of K virtual speakers, wherein the position information comprises an elevation angle index and an azimuth angle index, wherein K is a positive integer greater than 1, F≤K, and wherein F×S≥K.

An audio processing device, comprising:

one or more processors;
and
a memory, configured to store one or more programs, wherein
when the one or more programs are executed by the one or more processors, cause the one or more processors to:
determine a target virtual speaker from F preset virtual speakers based on a to-be-processed audio signal, wherein each of the F preset virtual speakers corresponds to S virtual speakers, wherein F is a positive integer, and wherein S is a positive integer greater than 1;
and
obtain, from a preset virtual speaker distribution table, respective position information of S virtual speakers corresponding to the target virtual speaker, wherein the virtual speaker distribution table comprises position information of K virtual speakers, wherein the position information comprises an elevation angle index and an azimuth angle index, wherein K is a positive integer greater than 1, wherein F≤K, and wherein F×S≥K.
