The program is designed for defining the identity of a sound signal with previously recorded patterns in real time mode and off-line mode. One of the main spheres of the program's application is the sound signal monitoring (TV, Radio, Video advertising announcements monitoring, advertisements editing, making songs ratings, roadcasting copyrights control etc.). According to the Russian law, each radio/TV channel must have the recording of its broadcasts for the past 30 days. This program can check when and how many times certain sound fragments (ads, songs, etc.) were broadcast, and it can also check the continuity of the fragment.
