AWT2 implements so called "blind watermarking" approach in the sense that the watermark can be extracted directly from the watermarked audio recording (so that the source audio is not needed).
AWT2 package does not require installation and can be used right after unpacking. It consists of encoder (watermark embedding tool), decoder (watermark extraction tool), GUI front-end utility, detailed User Guide and examples.
You can download AWT2 evaluation package here. Despite its limited functionality, the demo package offers enough flexibility to perform a variety of performance tests so that you can decide whether AWT2 suits your needs before buying a fully functional version.
AWT2 comes with an optional AWT2 Watermark Listener - free Android application that lets you use your portable Android device (phone, tablet) to detect digital watermarks in the audio content processed with AWT2 technology. Details...
This software is offered "as is". Please try and buy.

AWT2 GUI tool is available for Microsoft Windows, Apple Mac OS X and Linux (Gentoo, OpenSuse, Ubuntu) platforms. It comes with drag'n'drop support. Console AWT2 encoder and decoder are available for Windows, Mac OS X, Linux and FreeBSD. Other platforms can be supported upon request.
What it does and who it is for
AWT2 targets audio recording and production studios, on-line music stores, audio hosting services, broadcasting companies and other small and medium sized businesses. Here are some of the most common AWT2 applications:
Here is a very simplistic example of AWT2 usage. Imagine, you're a musician selling your tracks on the web. Using AWT2 you add a hidden inaudible digital signature (watermark) into every sold track. The signature contains your (creator's) identifier together with identifier of the target user who buys the track. Now imagine that later on you find your track on torrents or broadcasted on radio. You download or simply record the file and easily extract the signature from it. The signature confirms your ownership and indicates who was your "bad" customer who spread the file.
Evaluation (demo) version of AWT2 can be downloaded here:
AWT2 can be compiled for any platform not listed above. If you are interested in integration of AWT2 into your software, you can use AWT2 SDK, which is available for all major desktop, server and mobile platforms upon request.
The demo version of the encoder has limited functionality: the only permitted watermarks that can be embedded into audio stream are: 0x12, 0x56 (1 byte), 0x7890, 0x9876 (2 bytes), 0xABCDEF12, 0x12345678 (4 bytes), 0x112233445566 (6 bytes), 0x1122334455667788 (8 bytes) and 0x001122334455667788990011...8899 (40 bytes). This is quite strict limitation, however it offers enough flexibility to perform a variety of performance tests so that you can decide whether AWT2 suits your needs or not before buying fully functional version. If this limitation seems to you too strict and you wish to test the package with other watermarks, please feel free to contact AWT2 author by e-mail.
