description An audio watermark processing method includes: obtaining input audio; segmenting the input audio, to obtain audio segments; determining original frequency domain coefficients for the audio segments; obtaining embedding information including watermark information and mark information for positioning the watermark information; determining, based on the embedding information, adjustment information corresponding to a first original frequency domain coefficient of a first audio segment of the audio segments; performing an inverse frequency domain transformation on the adjustment information, to obtain a superimposing segment corresponding to the first audio segment; superimposing the first audio segment and a first superimposing segment, to obtain a target audio segment; obtaining target audio segments, embedded with the watermark information; and outputting target audio including the target audio segments.
