Claim 24:
25. A non-transitory computer-readable storage medium storing computer instructions, which when executed by one or more processors, cause the one or more processors to perform operations, the operations comprising:
obtaining T audio signals in a current frame, wherein T is a positive integer;
obtaining S groups of metadata in the current frame, wherein S is a positive integer, T>S, the S groups of metadata correspond to the T audio signals, and the metadata describes a status of a corresponding audio signal in a spatial scene;
determining a first audio signal set based on the T audio signals, wherein the first audio signal set comprises M audio signals, M is a positive integer, and T≥M;
determining M priorities of the M audio signals in the first audio signal set; and
performing bit allocation on the M audio signals based on the M priorities of the M audio signals;
wherein determining the M priorities of the M audio signals in the first audio signal set comprises:
obtaining a scene grading parameter of each of the M audio signals; and
determining the M priorities of the M audio signals based on the scene grading parameter of each of the M audio signals.
