1. An audio signal playing method, comprising:
separating, from a first audio signal, a recorded audio signal corresponding to each of at least one sound source;
determining, on the basis of the first audio signal, a real-time orientation of each of the at least one sound source relative to the head of a user;
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; and
playing a second audio signal generated by fusing the target direct audio signal and the target reverberated audio signal corresponding to each sound source,
wherein generating the target direct audio signal corresponding to the sound source comprises executing a first processing step for each sound source, comprising:
selecting a first convolution function corresponding to the real-time orientation of the sound source, wherein the first convolution function is used for extracting, from the audio signal, the target direct audio signal corresponding to the sound source; and
on the basis of the recorded audio signal corresponding to the sound source and a convolutional audio signal obtained by performing convolution with the selected first convolution function, generating the target direct audio signal corresponding to the sound source.
