Abstract
A method and apparatus for audio coding is disclosed, comprising: dividing an input audio signal into a low band signal and a high band signal; Identifying the type of the low band signal and the high band signal, wherein the different types of low band signal and the high band signal respectively correspond to different coding modes; Adaptively allocating an overall input rate of the audio signal to the lowband signal and the highband signal according to different coding modes corresponding to the lowband signal and the highband signal, wherein the lowband signal has a lowband Adaptively allocating a rate and allocating a highband signal to the highband signal; And coding a low band signal through a coding mode corresponding to the low band signal according to the low band speed, and coding a high band signal through a coding mode corresponding to the high band signal according to the high band speed. Include. In the embodiment of the present invention, when the low band signal and the high band signal are coded, no coding is performed according to the speed given in the standard or the speed set before the coding, and the coding speed is adaptively adapted to the different types of signals. Adjustment, thereby improving the overall audio coding performance.
