Abstract
A three-dimensional audio signal encoding method and apparatus, and an encoder are provided, and relate to the multimedia field. The method includes: The encoder obtains a first quantity of current-frame initial vote values for a current frame of a three-dimensional audio signal. Then, the encoder obtains, based on the first quantity of current-frame initial vote values and a sixth quantity of previous-frame final vote values, a seventh quantity of current-frame final vote values that are of a seventh quantity of virtual loudspeakers and that correspond to the current frame. Further, the encoder selects a second quantity of current-frame representative virtual loudspeakers from the seventh quantity of virtual loudspeakers based on the seventh quantity of current-frame final vote values. The encoder encodes the current frame based on the second quantity of current-frame representative virtual loudspeakers, to obtain a bitstream.
