Audiowmark is an Open Source (GPL) solution for audio watermarking.
Audiowmark is an Open Source (GPL) solution for audio watermarking. A sound file is read by the software, and a 128-bit message is stored in a watermark in the output sound file. For human listeners, the files typically sound the same. However, the 128-bit message can be retrieved from the output sound file. The process of retrieving the message does not need the original audio file (blind decoding). Internally, audiowmark is using the patchwork algorithm to hide the data in the spectrum of the audio file.
