Abstract
This application discloses a three-dimensional audio signal coding method and apparatus, and an encoder, and relates to the multimedia field. The method includes: After determining a first quantity of virtual speakers and a first quantity of vote values based on a current frame of a three-dimensional audio signal, a candidate virtual speaker set, and a voting round quantity, the encoder selects a second quantity of representative virtual speakers for the current frame from the first quantity of virtual speakers based on the first quantity of vote values, and further encodes the current frame based on the second quantity of representative virtual speakers for the current frame to obtain a bitstream. This achieves efficient data compression.
