Audio data processing method and device, computer equipment and storage medium

The embodiment of the invention discloses an audio data processing method and device, computer equipment and a storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining a frequency spectrum image of target audio data, obtaining a target expression parameter set matched with the frequency spectrum image of the target audio data based on a mapping relation between the frequency spectrum image and the expression parameter set, and adjusting a template face model according to the target expression parameter set to obtain a target face model with a facial expression. The invention includes obtaining a target expression parameter set matched with the target audio data based on a mapping relation between the spectrum image and the expression parameter set, wherein target expression parameters in the target expression parameter set are used for simulating facial expressions when the singer sends the audio data; obtaining a target face model with facial expressions ac
