A new algorithm can hide messages in your favorite dance music
It’s long been known that secret messages can be included in music through techniques such as backmasking, but now a Polish researcher has developed an entirely new approach. By subtly varying the tempo of a particular type of dance music, he’s managed to encode information in a way that’s completely inaudible to human listeners.
StegIbiza is an algorithm for hiding information in a type of dance music known as Ibiza, which originates on the island by the same name in the western Mediterranean Sea. Ibiza music is characterized by its trance-like beat, and that’s what Krzysztof Szczypiorski, a professor at Poland’s Warsaw University of Technology, made use of.
