Audio signal processing method and electronic device

An electronic device, comprising:

• a processor, and a memory configured to store executable instructions of the processor, wherein when the processor is configured to execute the instructions, the electronic device is enabled to perform a method in an audio system, wherein the audio system comprises the electronic device and a headset that are communicatively connected, the method comprising:
• splitting an audio signal into a direct part and a diffusion part;
• obtaining a corresponding room impulse response from a preset room impulse response database based on a current scene, wherein the room impulse response database comprises room impulse responses corresponding to scenes, and the current scene is a scene in which the electronic device is currently located;
• performing synthesis based on the room impulse response and a head-related transfer function to obtain a first binaural room impulse response for sense-of-orientation rendering and a second binaural room impulse response for sense-of-space rendering;
• rendering the direct part of the audio signal and the diffusion part of the audio signal based on the first binaural room impulse response to obtain a sense-of-orientation rendered audio signal;
• rendering the diffusion part of the audio signal based on the second binaural room impulse response to obtain a sense-of-space rendered audio signal;
• and
• synthesizing the sense-of-orientation rendered audio signal and the sense-of-space rendered audio signal, and inputting a synthesized signal to the headset.

A computer-readable storage medium, storing computer program instructions, wherein when the computer program instructions are executed by an electronic device, the electronic device is enabled to perform a method applied to an electronic device in an audio system, wherein the audio system comprises the electronic device and a headset that are communicatively connected, the method comprising:

• splitting an audio signal into a direct part and a diffusion part;
• obtaining a corresponding room impulse response from a preset room impulse response database based on a current scene, wherein the room impulse response database comprises room impulse responses corresponding to scenes, and the current scene is a scene in which the electronic device is currently located;
• performing synthesis based on the room impulse response and a head-related transfer function to obtain a first binaural room impulse response for sense-of-orientation rendering and a second binaural room impulse response for sense-of-space rendering;
• rendering the direct part of the audio signal and the diffusion part of the audio signal based on the first binaural room impulse response to obtain a sense-of-orientation rendered audio signal;
• rendering the diffusion part of the audio signal based on the second binaural room impulse response to obtain a sense-of-space rendered audio signal;
• and
• synthesizing the sense-of-orientation rendered audio signal and the sense-of-space rendered audio signal, and inputting a synthesized signal to the headset.
