My name is Alex Radzishevsky, I am an inventor and developer of audio technologies for digital signal processing. I founded (.info) in 2009. AudioWatermarking is a technology provider offering proprietary licensable audio watermarking and acoustic fingerprinting solutions.

I have patented* a novel watermarking approach that differs from other "common" watermarking techniques such as spread spectrum, echo hiding, etc., and enables very efficient, robust and imperceptible watermarking of audio signals with at a watermarking data rate. So far, I have developed three complete watermarking solutions based entirely on this invention but using it in different ways.

I have also received a patent* for a novel acoustic fingerprinting technique. This patented technique enables my audio fingerprinting software solution, which  features high scalability, speed and robustness.

I license these core technologies for use in varios fields and applications related to audio and sound.

A list of my patents and white papers can be found  here.
