Original Abstract Submitted
a signal processing method and device includes obtaining spectral coefficients of a current frame of an audio signal, in which n sub-bands of the current frame comprises at least one of the spectral coefficients. a total energy of m successive sub-bands of the n sub-bands, a total energy of k successive sub-bands of the n sub-bands, and an energy of a first sub-band are obtained to determine whether to modify original envelope values of the m sub-bands. when the original envelope values of the m sub-bands are modified, encoding bits are allocated to each of the n sub-bands according to the modified envelope values of the m sub-bands.
