Audio Watermarking Tools 2 (AWT2)

Audio Watermarking Tools 2 (AWT2) of www.audiowatermarking.info are shareware utilities for embedding (and extracting) short data payload within audio streams (wave files). The tools are distributed as a package of GUI and console utilities running on Microsoft Windows, Apple Mac OS X and Linux. The watermark is highly robust. It survives almost all kinds of audio conversions: transcoding using MP3, Ogg Vorbis, air transducing, etc.
