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