13. A signal processing method, comprising:
in a signal processing device;
acquiring first polar coordinate position information, audio data of a first object, absolute coordinate position information, and audio data of a second object, wherein the first polar coordinate position information indicates a position of the first object based on polar coordinates, and the absolute coordinate position information indicates a position of the second object based on absolute coordinates;
converting the absolute coordinate position information into second polar coordinate position information indicating the position of the second object; and
performing rendering processing based on the first polar coordinate position information and the audio data of the first object and the second polar coordinate position information and the audio data of the second object.
