We offer a set of tools for marking audio files (wav, mp3). The algorithm embeds inaudible marks as to prevent their removal without damaging the file. Marked files can be burned to a CD, converted into another format, edited, and hidden on the entire length of the file, watermark still be readable using special software.
Audio WaterMark technology of marking, music files, audiobooks.
Audio Watermark (digital marking of audio files) it process of embedding characters in beeps. The signs/mark can identify a specific buyer track in the online store (transactional watermark). For buyers, this means full freedom of use, can listen to purchased music on different devices (MP3 players, cell phones, computers). Marking the Audio Watermark, gives users complete freedom in contrast to the DRM (Digital Rights Management), where the user is forced to use a special software and the compatible devices.
Audio Watermark isan ideal solution for online stores selling music ,audiobooks and other files as mp3, wav files to download. In the absence of labeling of all copies sold are identical, and the identification of the purchaser is very difficult. Using Audio Watermark for marking Watemark Transaction, which will contain the transaction code and explicitly pointed to a particular buyer eliminates this problem. Reading the hidden characters in the audio file, requires special decoder, available in the Toolkit Audio Watermark and can be exercised only by this system, that made the mark. *(Read out the mark does not contain personal data, credit cards information, logins or passwords. Contain only the ID, which points to a specific client in a database system, so personal information is secure).
Signs affixed by the Audio Watermark tools do not give up even when trying to analog copying. Hidden characters and scattered along the entire length of the file are difficult to identify. Any attempt to remove, modify, blur information, ends damage to the file. Even though you try to record a song by a microphone applied to the loudspeaker, on analog tape, ends in failure, the characters are still legible. While converting audio files into other formats, editing, or division into fragments is possible to read the plotted characters. In addition to copyright protection, watermarking is also clear evidence for the buyer, that he has a right to use the purchased copy. Use of Audio Watermark Technology means for publishers, authors, producers guarantee the identification of the file owner in case of abuse.
Audio Watermark Tool Kit consists of two programs: Encoder – program used to impose watermarks. Marks may have a length, from 1 to 120 bytes. The most effective sign should contain up to 8 bytes with scattered along the entire length of the file. The program can operate in several modes, allowing you to set the density and resilience, but at the expense of efficiency/speeds. Encoder can also serve to mark the popular video formats. Normal speed marking on the Intel Core 2 Duo 2.0 GHz with default parameters allows the marking of 20x playback speed using a single processor core. Appropriate set of scripts, will allow the marking Audiobook which consists of multiple files using several processors. In practice, it is possible to marking an audiobook with a length of 500 minutes in 3 minutes, on processor: 2x Intel Xeon QuadCore 2.0 GHz. Audio Watermark offers probably the most resilient characters deposition, available on the Internet.
Decoder – program used to read the characters through in-depth analysis of the source file. With the supplied library ffmpeg, it is possible to analyze the source files in various formats: mp3, wav, acc, ogg, amr, etc. Decoder can find the characters in files from analog recordings, fragments of songs, mixed and blended, edited and converted to other formats. High effectiveness of this program means that he can read characters in the tracks that also serve as a background of the movie, broadcast radio, etc..
Audio Watermark Tool Kit is available on different OS platforms: Windows, Linux, FreeBSD, OSX and various processors 32 and 64 bit. Depending on demand, we prepare version for a specific system.
The programs operate in an environment character so you can freely use in popular shell scripts bash, sh, etc.. Additional facilitation is a graphical interface for the Encoder and Decoder, which will allow use the software in the graphical environments.
