1. A method for decoding an audio signal, comprising:

  • receiving a bitstream including a plurality of spectral coefficient parameters;

    obtaining, based on the spectral coefficient parameters, spectral coefficients of a current frame of the audio signal by decoding the received bitstream;

    classifying a sub-band of the current frame as a bit allocation un-saturated sub-band;

    restoring a spectral coefficient associated with the hit allocation un-saturated sub-band by performing noise filling; and

    obtaining a frequency domain signal according to the obtained spectral coefficients and the restored spectral coefficient, associated with the bit allocation un-saturated sub-band.
