1. An electronic device, comprising:
an auxiliary microphone with a sound pickup protection structure;
a first main microphone without the sound pickup protection structure;
a second main microphone without the sound pickup protection structure;
at least one storage medium storing at least one set of instructions; and
at least one processor in communication with the at least one storage medium, wherein during operation, the at least one processor executes the at least one set of instructions to:
obtain a first main audio signal collected by the first main microphone, a second main audio signal collected by the second main microphone, and an auxiliary audio signal collected by the auxiliary microphone,
obtain a first frequency domain signal corresponding to the first main audio signal and a second frequency domain signal corresponding to the second main audio signal,
determine feature information based on a correlation between the first frequency domain signal and the second frequency domain signal, wherein the feature information comprises wind noise degree information, and
synthesize a target audio signal from a target main audio signal and the auxiliary audio signal based on the feature information, wherein the target main audio signal is the first main audio signal or the second main audio signal.
