Claim:
1. An audio signal processing apparatus, comprising a non-transitory memory storing instructions; and a processor coupled to the non-transitory memory and configured to execute the instructions to: acquire an audio-left channel super-directional differential beamforming weighting coefficient and an audio-right channel super-directional differential beamforming weighting coefficient when the output signal type required by the current application scenario is a dual-channel signal type; perform super-directional differential beamforming processing on the audio input signal according to the audio-left channel super-directional differential beamforming weighting coefficient in order to obtain an audio-left channel super-directional differential beamforming signal; perform super-directional differential beamforming processing on the audio input signal according to the audio-right channel super-directional differential beamforming weighting coefficient in order to obtain an audio-right channel super-directional differential beamforming signal; transmit the audio-left channel super-directional differential beamforming signal and the audio-right channel super-directional differential beamforming signal; and
