Audio rendering method and apparatus

An audio rendering method, comprising:

• obtaining a to-be-rendered binaural room impulse response (BRIR) signal, wherein an elevation angle corresponding to the to-be-rendered BRIR signal is 0 degrees;
• correcting, based on a target elevation angle, a frequency-domain signal corresponding to the to-be-rendered BRIR signal;
• and
• performing frequency-time conversion on a corrected frequency-domain signal to obtain a BRIR signal of the target elevation angle.

An audio rendering method, comprising:

• obtaining a to-be-rendered binaural room impulse response BRIR signal, wherein an elevation angle corresponding to the to-be-rendered BRIR signal is 0 degrees;
• obtaining a head related transfer function (HRTF) spectrum corresponding to a target elevation angle;
• and
• correcting the to-be-rendered BRIR signal based on the HRTF spectrum corresponding to the target elevation angle, to obtain a BRIR signal of the target elevation angle.

An audio rendering apparatus, comprising:

• a memory storing instructions;
• and
• a processor, wherein execution of the instructions by the processor cause the apparatus to:
• obtain a to-be-rendered binaural room impulse response BRIR signal, wherein an elevation angle corresponding to the to-be-rendered BRIR signal is 0 degrees;
• obtain a direct sound signal based on the to-be-rendered BRIR signal, wherein the direct sound signal corresponds to a first time period in a time period corresponding to the to-be-rendered BRIR signal;
• correct, 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;
• obtain a time-domain signal based on the frequency-domain signal of the target elevation angle;
• and
• superpose 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 the first time period, to obtain a BRIR signal of the target elevation angle.
