My name is Alex Radzishevsky, I'm inventor and developer of digital signal processing audio technologies.

I've patented* a novel 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 fully based on this invention, but use it in different ways.

I've also received a patent** for a novel acoustic fingerprinting approach that I've developed. This patented approach powers my audio fingerprinting software solution that features high scalability, speed and robustness.

I license these core technologies for using in different fields and applications involving audio and sound.

Please refer to a list of my patents and white papers here.
