1. An audio signal processing method, applied to an electronic device in an audio system, wherein the audio system comprises an electronic device and a headset that are communicatively connected, and the method comprises:
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.
