Abstract

The invention discloses a sound signal processing method and device and a computer readable storage medium. The method comprises the steps: obtaining the delay time and signal compensation parameters of a second pickup channel relative to a first pickup channel; according to the delay time, acquiring a first sound signal corresponding to a first pickup channel and a second sound signal comprising sound transmitted by a second pickup channel from sound signals received by the microphone; according to the delay time, performing delay processing on the first sound signal, and according to the signal compensation parameter, performing compensation processing on the second sound signal; and obtaining a target sound signal according to the first sound signal after the delay processing and the second sound signal after the compensation processing, and outputting the target sound signal. According to the technical scheme of the invention, the cost for realizing the sound space directivity can be reduced.

Description

technical field [0001] The invention relates to the technical field of sound processing, in particular to a sound signal processing method, sound signal processing equipment and a computer-readable storage medium. Background technique [0002] At present, for acoustic products (including but limited to head-mounted VR devices or head-mounted AR devices or earphones, etc.), when sound noise is reduced, the general microphone array is used to realize the spatial directivity of the sound and improve the voice quality. However, the microphone array needs to use multiple microphones, and the cost is high. Contents of the invention [0003] The main purpose of the present invention is to propose a sound signal processing method, aiming at reducing the cost of realizing sound spatial directivity. [0004] In order to achieve the above object, the sound signal processing method proposed by the present invention is used in a sound signal processing device, the sound signal process...
