Abstract
An audio coding method and device. The method comprises: dividing input audio signals into low band signals and high band signals (101); identifying the types of the low band signals and the high band signals respectively (102); allocating the total input rate of the audio signals to the low band signals and the high band signals adaptively according to different coding modes corresponding to the low band signals and the high band signals (103); and coding the low band signals according to the low band rate through the coding mode corresponding to the low band signals, and coding the high band signals according to the high band rate through the coding mode corresponding to the high band signals (104). The coding of low band signals and high band signals is not performed according to the rate given in the standard or set prior to coding, and instead, the coding rate is adjusted adaptively according to different types of the signals, so that the overall performance of audio coding is improved.
