Audio rendering method, audio rendering apparatus and electronic apparatus

An electronic apparatus comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the processor is configured to perform an audio rendering method based on instructions stored in the memory device, the method comprising:
• obtaining scene-related audio metadata, wherein the scene-related audio metadata comprises a state and an energy of each sound propagation path between a sound source and a listener;
• determining a parameter for audio rendering based on the audio metadata, wherein the parameter for audio rendering comprises an energy attenuation coefficient for each sound propagation path, and wherein determining the parameter for audio rendering based on the audio metadata comprises adjusting the energy attenuation coefficient of each sound propagation path based on the state and the energy of the sound propagation paths;
• performing spatial audio coding on an audio signal of the sound source based on the parameter for audio rendering so as to obtain an encoded audio signal;
• and
• performing spatial audio decoding on the encoded audio signal so as to obtain a decoded audio signal for audio rendering.

A non-transitory computer-readable storage medium having a computer program stored thereon, that, when executed by a processor, implements an audio rendering method comprising:

• obtaining scene-related audio metadata, wherein the scene-related audio metadata comprises a state and an energy of each sound propagation path between a sound source and a listener;
• determining a parameter for audio rendering based on the audio metadata, wherein the parameter for audio rendering comprises an energy attenuation coefficient for each sound propagation path, and wherein determining the parameter for audio rendering based on the audio metadata comprises adjusting the energy attenuation coefficient of each sound propagation path based on the state and the energy of the sound propagation paths;
• performing spatial audio coding on an audio signal of the sound source based on the parameter for audio rendering so as to obtain an encoded audio signal;
• and
• performing spatial audio decoding on the encoded audio signal so as to obtain a decoded audio signal for audio rendering.
