AWT3 overview

--== NOTE: AWT3 is now deprecated and is replaced with AWT5 ==--

Audio Watermarking Tools 3 (AWT3) is an audio trigger and watermarking solution specially designed for reliable far-field over-the-air digital signaling. The list of possible uses includes "second screen" synchronization, "kick-shopping", triggering, events initiation, handshake and data transmission over-the-air by means of sound waves. AWT3 codes can be reliably detected even on large distances such as cinema halls and stadiums. AWT3 is an ultra-sonic extension of AWT2 and is fully based on its patented technique.
