My name is Alex Radzishevsky, I'm sole inventor and developer. I've patented* a unique watermarking approach that differs from other "common" watermarking techniques (such as spread spectrum, echo hiding, etc.) and allows very efficient, robust and imperceptible watermarking of audio signals with high watermarking data rate. So far I developed three complete watermarking solutions which are based on this invention, but use it in different ways.
