Audio Watermarking Tools 2 (AWT2) is a set of software utilities for embedding (and retrieving) digital watermarks within (from) audio files. AWT2 uses proprietary patented technology to imperceptibly embed watermarks directly into the audio content so that they cannot be removed without damaging the original audio quality. The tools are distributed as a package of GUI and console utilities running on Microsoft Windows 7/Vista/XP/NT/2000/Server, Apple Mac OS X and Linux/*nix systems; both x86 and x64 versions are available. SDK is also available for different platforms.

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.

AWT2 highlights:
  - free evaluation package (no risk, no obligations, no registration)
  - cross-platform software (Windows, Linux, Mac OS, ...)
  - intuitive GUI front-end with drag-and-drop support
  - console tools for easy automation and quick deployment on servers
  - detailed documentation with examples and tips
  - flexibly configurable algorithm
  - industrial grade watermarking performance providing
      · truly robust watermarks
      · very high watermarking data rate
  - unique, proprietary, patented technology
  - dual-layer watermarking support
  - SDK available
      · cross-platform
      · fully thread-safe
      · with true real-time audio stream encoding functionality
  - free life-time updates
  - individual customer support
  - fair pricing
  - free supplementary Android app (read more...)

AWT2 performance highlights:
AWT2 watermarks are inaudible and highly robust, surviving low bitrate transcoding with lossy coders, mixing, effect processing, acoustic coupling (transducing via air) and time stretching. Check examples section.
AWT2 offers unprecedentedly high watermarking data rate up to 125 bps (i.e. more than 16 bytes in one second of audio); watermark payloads up to 120 bytes long are supported.

AWT2 brings reliable watermarking to your business. AWT2 protects your rights by ensuring that your watermark is detectable (only by you!) in any copy of your audio materials transmitted or broadcasted anywhere.

AWT2 package is free to try. Evaluation (demo) version of AWT2 with limited functionality is available and can be downloaded absolutely free. 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 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...

What it does and who it is for

AWT2 targets individual musicians, composers, music authors and music owners, 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:

  • content signing and ownership ascertainment (audio content is marked by a special digital signature stating your ownership) - most relevant for audio content authors and owners such as musicians, recording labels and studios
  • copy protection and monitoring (each recipient gets his own copy of audio an material copy watermarked with unique signature) - most relevant for web-stores, broadcasting companies

Here is a very simple 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.

If you need AWT2 for a platform not listed above, please do not hesitate to contact AWT2 author.

If you are interested in integration of AWT2 into your software, you can use AWT2 SDK, which is available for all major 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.
