Coding system for protecting sound recordings by analog remastering, has original master audio on any type of medium such as compact disk or digital video disk with help of phase encoding audio software

摘要

The coding system has an original master audio on any type of medium such as compact disk or digital video disk with the help of a phase encoding audio software. The phase encoding audio software is transformed into a coded master audio for establishing a specific decoding key (5). The specific decoding key allows the conversion of coded master audio in a decoded hearing audio so that the security derives from the anti-replay audio in the absence of the appropriate key.
