Problems solved by technology
However, when the main microphone is facing the direction of the wind, the sound pressure level of the wind noise collected by the main microphone is usually very high, so that the main sound signal processed by the noise canceling module is still not recognized by the human ear, thus causing a call Quality drops, affecting user call experience

The invention relates to a microphone wind noise elimination method and device, a storage medium and a mobile terminal. The method comprises the steps: obtaining a first voice signal received by a main microphone when voice signals are received through a plurality of microphones; determining whether wind noise occurs in the main microphone or not according to a peak factor of the first voice signal, wherein the peak factor is used for representing the clipping distortion degree of the first voice signal; and when wind noise occurs in the main microphone, a target voice signal is switched fromthe first voice signal to a second voice signal received by the auxiliary microphone, and the target voice signal is a main voice signal adopted when the denoising module performs voice signal processing and outputting. According to the invention, when wind noise occurs in the main microphone, the voice signals collected by the auxiliary microphones arranged at different positions are used as themain voice signals for voice transmission of the mobile terminal, so that the influence of wind noise on the call quality is reduced, and the user experience of mobile terminal call is improved.
Description
technical field [0001] The present disclosure relates to the field of mobile terminal design, and in particular, to a microphone wind noise cancellation method, device, storage medium and mobile terminal. Background technique [0002] When a mobile terminal user holds a mobile terminal to make a call in a windy environment, the sound collected by the microphone will be affected by the wind, resulting in wind noise. In related technologies, in order to reduce the impact of noise on call quality, most mobile terminals will set two or more microphones at different positions, and receive the sound signals collected by multiple microphones through the noise canceling module; The sound signal collected by the main microphone at the bottom of the mobile terminal is used as the main sound signal, and the sound signal collected by the auxiliary microphone installed in other positions is used as a reference signal to perform noise reduction processing on the main sound signal, and out...
