Abstract: This application provides an audio rendering method, including: obtaining a to-be-rendered BRIR signal, where an elevation angle corresponding to the to-be-rendered BRIR signal is 0 degrees; obtaining a direct sound signal based on the to-be-rendered BRIR signal; correcting, based on a target elevation angle, a frequency-domain signal corresponding to the direct sound signal, to obtain a frequency-domain signal corresponding to the target elevation angle; obtaining a time-domain signal based on the frequency-domain signal of the target elevation angle; and superposing the time-domain signal on a signal that is in the to-be-rendered BRIR signal and that is in a second time period after a first time period, to obtain a BRIR signal of the target elevation angle.
