Abstract  Abstract

Embodiments of the present invention disclose a voice / audio signal processing method and apparatus. In one embodiment, the audio / audio signal processing method includes obtaining an initial high frequency signal corresponding to a current frame of the audio / audio signal when the audio / audio signal switches bandwidth; Obtaining a time domain global gain parameter of the signal, weighting the energy ratio and the time domain global gain parameter, and using the obtained weighted value as the predicted global gain parameter, To obtain a corrected high frequency time domain signal, where the energy ratio is the ratio between the past frame energy of the high frequency time domain signal and the current frame energy of the initial high frequency signal Use predicted global gain parameters Therefore comprising a step of correcting the initial high frequency signal, by combining the current frame and the corrected high-frequency several time-domain signal of a narrow frequency time domain signal, and outputting a combined signal.
