About the inventor
My name is Alex Radzishevsky. I am an inventor and developer of digital audio signal processing technologies. I started developing my audio watermarking technology in 2007, and in 2009 I established AudioWatermarking.com (.info) as a specialist technology provider of proprietary audio watermarking and acoustic fingerprinting solutions.
My patented* audio watermarking approaches differ from traditional methods such as spread spectrum and echo hiding by offering efficient, robust, and imperceptible watermarking of audio signals at high data rates. I have developed multiple watermarking solutions based on patented DSP techniques that I invented.
I also hold a patent* for a novel acoustic fingerprinting technique that enables highly scalable, fast, and robust audio fingerprinting and matching.
I license these core technologies for use in a wide range of audio and sound applications, including digital delivery of music and spoken-word content, audio authenticity and proof of authorship, music recognition, protection of sensitive recordings, airplay monitoring, interactive and event-based experiences, over-the-air signaling, second-screen synchronization, and AI-era audio authenticity workflows.
As an independent developer, I work with every customer directly. You discuss your project with the person who designed the algorithms and develops the software — from the first evaluation to integration support.
A list of patents, white papers, and related technical publications is available on the White Papers page. Selected companies already using my technologies are listed on the Customers page.
