AWT3 overview

Audio Watermarking Tools 3 (AWT3) is an archived audio triggering and watermarking solution originally designed for reliable far-field over-the-air digital signaling. Typical uses included second-screen synchronization, interactive experiences, triggering, event initiation, handshake, and data transmission over the air by means of sound waves. AWT3 is an ultrasonic extension of AWT2 and is based on the same patented technique.
