A1
Abstract:
An audio signal playing method and apparatus, and an electronic device. The method comprises: separating, from a first audio signal, a recorded audio signal corresponding to each of at least one sound source (101); on the basis of the first audio signal, determining a real-time orientation of each of the at least one sound source relative to the head of a user (102); for each sound source, according to the real-time orientation of the sound source and the recorded audio signal corresponding to the sound source, generating a target direct audio signal corresponding to the sound source, and generating a target reverberated audio signal corresponding to the sound source (103); and playing a second audio signal that is generated by means of fusing the target direct audio signal and the target reverberated audio signal corresponding to each sound source (104). By means of the method, a sound field formed by at least one sound source can be accurately restored.
