Re: Q spoiler
'Q-Spoiler' is a method to plug the Analog Hole which inserts data into digital audio files that is inaudible as long as the file is played “as is.”

Q-Spoiler also prevents conversion through codecs, e.g. CD to MP3 for P2P
file swapping. Therefore preventing the creation of MP3 or WAV files that
can be then loaded to the Internet.

Unlike existing CD copy protection, which tries to make CD music files invisible or unreadable to computers and other copiers, Darknoise(UK company) actually modifies the audio of the songs slightly. If those songs are then copied--even by holding a tape recorder in front of a stereo speaker--the formerly inaudible Darknoise addition becomes audible and makes the copy unlistenable.
