The genome project - music style
The RAA project, funded by the EC is just such an approach of watermarking technologies that has resulted in an application called AudioDNA. AudioDNA uses a unique fingerprinting approach that requires anything between 5 to 60 seconds in order to establish copyright and identity details of music and commercial advertising broadcasted either over the Internet or live over the air. While numerous copyright protection programs are available, they all face the same unique problems, one of which is the most commonplace; signal variance. Whether a song is broadcast over Internet radio or live over the air, its signal will vary accordingly. Additionally, its original format also incorporates signal variance, making an MP3 format register quite differently from a standard CD audio format. Therefore, what is required is a program that not only traces all incidences of a song's distribution, but also has the means to interpret its variance of signal in order to derive its legality. Given that the introduction of new technologies has made the distribution of illegal content more common than its legal consumption, the arena for control is vast. Therefore AudioDNA's application ability to monitor three audio input signals simultaneously is a vital step forward for IPR preservation. Combined with the fact that it need but monitor several seconds of a song or commercial in order to determine its legal status, gives it the capacity to register thousands of hits an hour. Based on C++ the AudioDNA compiles several functionalities. There is the AudioDNA Extractor, the basic engine that seeks, monitors and analyses input signals. There is the AudioDNA Music Monitor, capable of storing 50 000 titles, identifying titles within a minimum of 10 seconds. The AudioDNA Commercial Monitor performs similarly, but is used to identify audio commercials broadcast either over radio or television. Perhaps one of the core attractions to this technology revolves around more than just the technology behind AudioDNA, it is also a comprehensive system to preserve the European music industry by attempting to root out its largest undermining influence: piracy.
