Techopedia Explains Constrictor
If someone is trying to copy an audio, a type of constrictor software is put into place to significantly lowers the audio quality, decreasing potential for copying it. The video also can be distorted and not easily viewed. Constrictor software actively degrades the quality of any copy, thus preventing the pirating or distribution of such unauthorized copies.
