These audio watermark shareware command line utilities embed and retrieve a short data payload within and from audio wav files. Once embedded within the audio content, the watermarks persist through a wide range of audio manipulations ranging from compression (such as MP3 for instance) to down-sampling and even acoustic coupling. These standalone executables require no installation other than being copied on your drive. In their demo mode, they offer enough features to perform a variety of performance tests so that you may assess whether they fit your needs before purchasing any license.
