Abstract: A audio signal processing method includes: sampling and holding, in a time sharing manner, an audio-left channel analog signal output by an audio-left channel microphone of a stereo headset and an audio-right channel analog signal output by an audio-right channel microphone; performing analog-to-digital conversion on the audio-left channel analog signal and audio-right channel analog signal that are sampled and held, so as to obtain a corresponding audio-left channel digital signal and an audio-right channel digital signal; performing data encapsulation on the audio-left channel digital signal and the audio-right channel digital signal to obtain a serial digital signal; and receiving and demodulating, by a terminal, the serial digital signal to obtain an audio-left channel digital signal and an audio-right channel digital signal.

Abstract: A sound signal processing method includes: receiving direction indication information input by a user and used for indicating a target direction (S110); and adjusting, according to the direction indication information, a beam direction of a sound signal processing array to the target direction (S120). A sound signal processing device includes: a receiving module (810), configured to receive direction indication information input by a user and used for indicating a target direction; and an adjustment module (820), configured to adjust, according to the direction indication information, a beam direction of a sound signal processing array to the target direction. According to the sound signal processing method and device, a beam direction of a sound signal processing array is adjusted according to direction indication information a target direction, so that a sound signal can still be accurately processed in a noisy environment, thereby achieving an enhancement effect for the processed sound signal.
