Abstract  Abstract

voice / audio signal processing method and apparatus embodiments of the present invention disclose a voice / audio signal processing method and apparatus. in one embodiment, the method of processing voice / audio signals includes: when an alternating band voice / audio signal, obtaining an initial high frequency signal corresponding to a current voice / audio signal frame; obtaining a global gain parameter time domain of the initial high frequency signal; execution of weighting processing in an energy relation and the world gain parameter in the time domain, and using a weighted value obtained as a global gain parameter, where the energy proportion is a relation between the energy of a historical signal frame in the domain of high frequency time and energy of a current frame of initial high frequency signal; rectifies the initial high frequency signal, using the predicted global gain parameter, to obtain a corrected high frequency time domain signal; and synthesizing a current signal frame in the narrow frequency time domain and corrected high frequency time domain signal and outputting the synthesized signal.
