Abstract
The embodiment discloses an audio coding method and a device thereof. The method comprises the following steps of: dividing input audio signals into low band signals and high band signals; identifying the types of the low band signals and the high band signals respectively; allocating an input total 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; and coding the low band signals according to a low band rate through a coding mode corresponding to the low band signals, and coding the high band signals according to a high band rate through a coding mode corresponding to the high band signals. In the embodiment, the coding of the low band signals and the high band signals is not performed according to a 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.
