— Digital audio watermarking allows to imperceptibly embed (hide) secret digital signature (digital code) into acoustic content so that this information cannot be removed without damaging the original audio quality. The embedded inaudible information can be retrieved and used to verify authenticity of the audio content, identity of its owners or recipients, or serve as event trigger.
— Acoustic fingerprinting is a signal processing approach allowing identification, matching and comparison of audio recordings based on their compact digital acoustic fingerprints (“acoustic hashes”).

The family of AWT DSP solutions consists of the following core audio watermarking and fingerprinting software products:


AWT1	AWT1 – digital audio watermarking solution with insane robustness High grade robustness. Simple and effective.
AWT2	>>> AWT2 – flagship digital audio watermarking solution<<< Industrial grade performance, robustness, features and scalability. Reliable hidden “digital signing” for multipurpose use.
AWT3	AWT3 – far-field over-the-air acoustic triggering and signaling Especially designed for over-the-air applications.
AWT4	AWT4 – time-precise digital stamping and triggering For triggering and signaling over digital and analog audio channels with high timing accuracy.
AWT0	AWT0 (AWT-Zero) – inaudible signaling over lossless audio PCM channels Watermarking of extremely short wave files and triggering over completely lossless audio channels
AFT	AFT – robust acoustic fingerprinting solution Content matching, identification and monitoring by means of acoustic hashing
