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 and a family of algorithms designed to allow quantitative estimation of perceptual similarity of audio recordings based on their compact digital acoustic fingerprints (“acoustic hashes”).

A number of different core audio watermarking and fingerprinting software products are offered:

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
