AudioWatermark: insert inaudible information into an audio signal

AudioWatermark is state of the art steganography technology for hiding user defined information into an audio signal (live streams or recordings) and extract it later after transmission or distribution.

The watermark is inaudible, can't be read by unauthorized attackers and is robust to most usual channel distortions and compressions, including lossy MP3 or recoding. Because the watermark travels inside the audio signal itself and not at file level, it can even survive digital to analog conversions! In addition, the watermark detects manipulations like deletion, copy & paste of audio segments.

Now you can keep track of the identity of the user that fetched a specific recording, send information hidden into a radio broadcast or enforce copyright in streaming audio/video content.

AudioWatermark is available as a SDK developed in C++ for maximum efficiency, speed and easy of integration.
