The method includes: obtaining a first single-object audio track based on a multimedia file, where the first single-object audio track corresponds to a first sound object; determining a first sound source position of the first sound object based on reference information; and performing spatial rendering on the first single-object audio track based on the first sound source position, to obtain a rendered first single-object audio track.
