Abstract

An audio coding method and a related apparatus are disclosed. The audio coding method includes: performing time-frequency transformation processing on a time-domain signal of a current audio frame, to obtain spectral coefficients of the current audio frame; acquiring a reference coding parameter of the current audio frame; and if the acquired reference coding parameter of the 5 current audio frame satisfies a first parameter condition, coding the spectral coefficients of the current audio frame based on a transform coded excitation algorithm, or if the acquired reference coding parameter of the current audio frame satisfies a second parameter condition, coding the spectral coefficients of the current audio frame based on a high quality transform coding algorithm. The audio coding method and the related apparatus help improve coding quality or coding 10 efficiency of audio frame coding. [Figure 1]
