We develop and license proprietary audio watermarking and acoustic fingerprinting software technologies for commercial and professional use. This is the home of Audio Watermarking Tools (AWT) and Audio Fingerprinting Tools (AFT) - robust DSP software solutions and services for forensic audio watermarking, steganography, acoustic signaling, and acoustic fingerprinting based on proprietary patented* technology.

Our technologies help professionals and organizations control the distribution of audio content, deter piracy, trace leaks, authenticate recordings and recipients, license and protect digital assets, embed data into audio for forensic and signaling purposes, monitor live streams and broadcasts, recognize music, synchronize playback time, de-duplicate audio content, and more.

— Digital audio watermarking allows an imperceptible digital signature or code to be embedded in audio content so it can later be detected and extracted for authentication, traceability, rights protection, or event triggering.
— Acoustic fingerprinting is a signal processing technique for identifying, matching, and comparing audio recordings by means of compact digital acoustic fingerprints (“acoustic hashes”) derived from the sound itself.
