Claim 2:
3. The method according to claim 1, wherein obtaining the scene grading parameter of each of the M audio signals comprises:
obtaining one or more of: a movement grading parameter, a loudness grading parameter, a spread grading parameter, a diffuseness grading parameter, a status grading parameter, a priority grading parameter, or a signal grading parameter of a first audio signal based on metadata corresponding to the first audio signal or based on the first audio signal and the metadata corresponding to the first audio signal, wherein the first audio signal is one of the M audio signals; and
obtaining a scene grading parameter of the first audio signal based on the obtained one or more of: the movement grading parameter, the loudness grading parameter, the spread grading parameter, the diffuseness grading parameter, the status grading parameter, the priority grading parameter, or the signal grading parameter, wherein
the movement grading parameter describes a movement speed of the first audio signal in a unit time in the spatial scene, the loudness grading parameter describes loudness of the first audio signal in the spatial scene, the spread grading parameter describes a spread range of the first audio signal in the spatial scene, the diffuseness grading parameter describes a diffuseness range of the first audio signal in the spatial scene, the status grading parameter describes sound source divergence of the first audio signal in the spatial scene, the priority grading parameter describes a priority of the first audio signal in the spatial scene, and the signal grading parameter describes energy of the first audio signal in an encoding process.
