We created the C ++ Watermark Library as a student project. It implements:

  • The less significant bit of the watermark (which will not resist anything)
  • Spread-Spectrum watermark (which should resist quite a bit, but very audibly)
  • There is MATLAB code for the compression-expansion algorithm, which is considered very reliable according to the document “Audio Watermark Using Frequency Compression Extension”.
