Abstract
An embodiment of the present invention provides a method and a decoding apparatus for predicting a bandwidth extended frequency band signal. The method includes demultiplexing a received bit stream and decoding the demultiplexed bit stream to obtain a frequency domain signal; Determining if the highest frequency bin to which the bits of the frequency domain signal are allocated is lower than a predetermined starting frequency bin of the bandwidth extension frequency band; If the highest frequency bin to which the bit is allocated is lower than a predetermined starting frequency bin of the bandwidth extension frequency band, an excitation signal within a predetermined frequency band range of the frequency domain signal and a preset Predicting an excitation signal of the bandwidth extension frequency band according to a start frequency bin; If the highest frequency bin to which the bit is allocated is higher than or equal to a predetermined starting frequency bin of the bandwidth extension frequency band, an excitation signal within a predetermined frequency band range of the frequency domain signal, And predicting an excitation signal of the bandwidth extension frequency band according to the highest frequency bin to which the bit is assigned; And predicting the bandwidth extension frequency band signal according to an excitation signal of the predicted bandwidth extension frequency band and a frequency envelope of the bandwidth extension frequency band. The technical solution of the embodiment of the present invention can effectively guarantee the continuity of the predicted excitation signal of the bandwidth extension frequency band between the previous frame and the following frame so that the voice quality of the restored bandwidth extension frequency band signal can be guaranteed have.
