Audio synchronization method and related device

The invention discloses an audio synchronization method and a related device, the method is applied to a microphone acquisition system comprising a first acquisition end and a second acquisition end, and the method comprises the following steps: acquiring a first frequency domain signal acquired by the first acquisition end and a second frequency domain signal acquired by the second acquisition end; obtaining phase angle information of the first frequency domain signal and the second frequency domain signal under a plurality of preset frequencies, and determining a phase difference mean value and a time difference mean value between the first frequency domain signal and the second frequency domain signal based on the phase angle information; and based on the phase difference mean value and the time difference mean value, adjusting the acquisition time delay of the first acquisition end and the second acquisition end. In this way, the calculation cost can be saved, and the audio synchronization efficiency can
