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

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 have 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. This patented technique empowers 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.
