More on the Shepard Tone,
A Shepard Tone, or Shepard-risset glissando, is an auditory illusion, where layered octaves cause a perception that the sound is endlessly rising or falling in pitch.
The app "ShepardTone" is a unique software interface to generate these sounds instantly
Despite the fact that Shepard Tone illusions are used all the time, in movies, games, and more, such as the famous Super Mario never-ending staircase or notably, the film Dunkirk, which uses it continuously throughout the film.
Christopher Nolan explicitly stated that he wrote the script for Dunkirk according to the mathematical principles of the Shepard tone, the auditory illusion deeply influenced the film from the start.
In fact, while I've always had a fascination with hallucinations or illusions in general, both visual, auditory, but ever since developing this application I've noticed this audio illusion is actually used a lot more than I initially realized, just last night I seen a rather interesting film called Backrooms, it featured subtle shepard tones in various moments, which fit the movie quite well to be honest.
So now you can have the most intense anticipation & suspense from all the movies, ever, basically, right at your fingertips to listen to purely for entertainment.
