Embodiment 1
[0051] figure 1 It is a flow chart of the audio signal processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the audio signal is processed in real time in the process of voice interaction to suppress noise. The method can be implemented by an audio signal processing device , the apparatus is configured in computer equipment, and specifically may be implemented by software and / or hardware in the computer equipment.
[0052] Such as figure 1 As shown, the audio signal processing method specifically includes:
[0053] S110. Acquire a far-end audio signal and a near-end audio signal, and group the far-end audio signal and the near-end audio signal according to preset frequency band groups to obtain sub-signals of multiple frequency bands.
[0054]Specifically, the far-end sound signal means that among the two parties performing voice interaction, for one of them, the other party's voice signal is the far-end sou...
