Audio watermark processing method and apparatus, computer device, and storage medium

An audio watermark processing apparatus, comprising:

• at least one memory configured to store computer program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• first obtaining code configured to cause at least one of the at least one processor to obtain input audio from an input audio signal, an input audio transmission, an input audio stream, or an input audio file;
• segmentation code configured to cause at least one of the at least one processor to segment the input audio to obtain a plurality of audio segments;
• first determining code configured to cause at least one of the at least one processor to determine a plurality of original frequency domain coefficients corresponding to the plurality of audio segments;
• watermark code configured to cause at least one of the at least one processor to obtain embedding information comprising watermark information and mark information for positioning the watermark information;
• first adjustment code configured to cause at least one of the at least one processor to determine based on the embedding information, adjustment information corresponding to a first original frequency domain coefficient of a first audio segment of the plurality of audio segments;
• second adjustment code configured to cause at least one of the at least one processor to perform an inverse frequency domain transformation on the adjustment information, to obtain a first superimposing segment corresponding to the first audio segment;
• superimposition code configured to cause at least one of the at least one processor to superimpose the first audio segment and the first superimposing segment, to obtain a target audio segment;
• second obtaining code configured to cause at least one of the at least one processor to obtain a plurality of target audio segments embedded with the watermark information;
• and
• outputting code configured to cause at least one of the at least one processor to output, as at least one of a target audio signal, a target audio transmission, a target audio stream, or a target audio file, target audio comprising the plurality of target audio segments,
• wherein the mark information comprises first mark information and second mark information, and the first mark information and the second mark information satisfy a preset similarity condition.

A non-transitory computer-readable storage medium, storing computer code which, when executed by at least one processor, causes the at least one processor to at least:

• obtain input audio from an input audio signal, an input audio transmission, an input audio stream, or an input audio file;
• segment the input audio to obtain a plurality of audio segments;
• determine a plurality of original frequency domain coefficients corresponding to the plurality of audio segments;
• obtain embedding information comprising watermark information and mark information for positioning the watermark information;
• determine based on the embedding information, adjustment information corresponding to a first original frequency domain coefficient of a first audio segment of the plurality of audio segments;
• perform an inverse frequency domain transformation on the adjustment information, to obtain a first superimposing segment corresponding to the first audio segment;
• superimpose the first audio segment and the first superimposing segment, to obtain a target audio segment;
• obtain a plurality of target audio segments embedded with the watermark information;
• and
• output, as at least one of a target audio signal, a target audio transmission, a target audio stream, or a target audio file, target audio comprising the plurality of target audio segments,
• wherein the mark information comprises first mark information and second mark information, and the first mark information and the second mark information satisfy a preset similarity condition.
