Abstract
An audio coding method and apparatus are disclosed, where the method includes: dividing an input audio signal into a low-band signal and a high-band signal; identifying types of the low-band signal and the high-band signal; adaptively allocating a total input rate of the audio signal to the low-band signal and the high-band signal according to different coding modes corresponding to the low-band signal and the high-band signal; and coding the low-band signal through a coding mode corresponding to the low-band signal according to the low-band rate, and coding the high-band signal through a coding mode corresponding to the high-band signal according to the high-band rate. In embodiments of the present application, when the low-band signal and the high-band signal are coded, coding rates are adaptively adjusted according to different types of the signals, thereby improving overall audio coding performance.
