More Information
Summary:The present application provides a bit allocating method and apparatus for audio signal. The bit allocating method for audio signal of the present application includes: obtaining T audio signals of a current frame, where T is a positive integer; determining a first audio signal set based on the T audio signals, where the first audio signal set include M audio signals, where M is a positive integer, the T audio signals includes the M audio spinals, T≥M; determining the priorities of the M audio signals of the first audio signal set respectively; performing bit allocation for the M audio signals based on the priorities of the M audio signals. The present application can adaptive to the characteristic of an audio signal, and different quantities of encoding bits are mapped to different audio signals, thus improve the encoding/decoding efficiency of the audio signal.
