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 to be carried by a user 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; decomposing the room impulse response into a direct part of the room impulse response, an early reflection part of the room impulse response, and a later reverberation part of the room impulse response; performing synthesis based on the direct part of the room impulse response, the early reflection part of the room impulse response, and a head-related transfer function corresponding to each orientation of the user's head to obtain a first binaural room impulse response for sense-of-orientation rendering, the sense-of-orientation rendering restoring a location of a sound source in a sound field; and performing synthesis based on the early reflection part of the room impulse response, the later reverberation part of the room impulse response, and another head-related transfer function in a preset orientation to obtain a second binaural room impulse response for sense-of-space rendering, the sense-of-space rendering achieving a sense of space and surround sound of a sound field; 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. 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; decomposing the room impulse response into a direct part of the room impulse response, an early reflection part of the room impulse response, and a later reverberation part of the room impulse response; performing synthesis based on the direct part of the room impulse response, the early reflection part of the room impulse response, and a head-related transfer function corresponding to each orientation of the user's head to obtain a first binaural room impulse response for sense-of-orientation rendering, the sense-of-orientation rendering restoring a location of a sound source in a sound field; and performing synthesis based on the early reflection part of the room impulse response, the later reverberation part of the room impulse response, and another head-related transfer function in a preset orientation to obtain a second binaural room impulse response for sense-of-space rendering, the sense-of-space rendering achieving a sense of space and surround sound of a sound field; 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.
