Audio gain control method and device, equipment and storage medium

The invention discloses an audio gain control method and device, equipment and a storage medium. The method comprises the following steps: acquiring a target audio signal, and performing voice analysis processing on the target audio signal to obtain audio frame information corresponding to each audio frame in the target audio signal; determining target short-time energy and a target spectrum centroid corresponding to the target audio frame according to the audio frame information; determining an actual audio frame type corresponding to the target audio frame according to the target short-time energy, the target spectrum centroid and a predetermined preset theoretical judgment threshold; determining a target gain ratio corresponding to the target audio frame based on the actual audio frame type and a preset curve vector; and according to the target gain ratio corresponding to the target audio frame, performing audio gain processing on the target audio signal, thereby simplifying the calculation step of the gai
