AWT solutions provide ways to back-trace distribution of audio content, prevent piracy, authenticate recipients, license the content digitally, embed and hide digital data for forensic purposes, track and monitor broadcasts by means of audio, enforce digital rights and more.
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:
In addition to the above core software technologies, audio watermarking is also offered as a completely FREE web-service via TrustedAudio.com:
