The audio signal to be separated may be an audio signal of a conference, or may be a recording of a public security trial, and the like. The audio signal to be separated may be an audio signal obtained by recording in advance from another recording device in a wired or wireless manner, or an audio signal directly collected in real time.
In order to improve the quality of the audio signal, the audio signal to be separated may be subjected to noise reduction processing to filter out noise signals present in the audio signal.
The extracting module 12 is configured to extract multiple frequency points of the audio signal, where the multiple frequency points are peak points of a frequency domain of the audio signal.

In order to separate the audio signals of all people, the separated audio signals are respectively used as new audio signals to be separated, the step of extracting a plurality of frequency points of the audio signals is returned to be executed until the maximum phase difference is smaller than a preset threshold value, the audio signals are considered to belong to the sound of the same person, and the audio signal separation is completed.

In the embodiment of the present invention, the first phase shift value and the second phase shift value are determined by taking as an example that the first phase shift value and the second phase shift value are obtained according to the difference between the phase corresponding to the two frequency points and 180 °, for example, when the phases of the two frequency points corresponding to the maximum phase difference are a ═ P (100Hz) and b ═ P (1800Hz), respectively, the first phase shift value may be (180-a), and the second phase shift value may be (180-b), where P (100Hz) and P (1800Hz) represent the phases corresponding to the frequency points of 100Hz and 1800 Hz.
