Hidden images in sound recordings
We all knew that secret messages could be hidden in audio tracks by using a process called backmasking, where a sound is played backwards on a track that is meant to be played forwards. But it doesn’t stop there: did you know that hidden messages can now be seen as well as heard? Below are a collection of rather spooky images created when passing certain tracks through a spectograph: a highly sensitive audio decrypter used primarily to identify the cries of animals.
Musicians, like Disasterpeace, have started to exploit this method and hide bonus viewing in their tracks for loyal and tech-savvy fans. More mainstream artists like Aphex Twin and Nine Inch Nails are also known to have used the technique.
