Do you know about the shepard tone?

Named after cognitive scientist Roger Shepard, this tone is a unique tone that is represented by a number of sine waves.

When you analyze it visually, it shows that the tone is either increasing or decreasing.

But that’s just an illusion, the octaves that separate it make it sound like it’s neither going up or down in overall pitch.

How does it work?

Your ears can get tricked because the tones that are increasing in pitch together are constantly changing in volume. The tone that is still increasing is the loudest of the three tones that you hear. You can generate tones with some amazing online tools.

The track loops, but the prominent tone is always the one that stands out to you. And, thus, it creates the Shepard tone illusion, where your ears believe that the tone is ascending infinitely.

Why does the Shepard tone illusion matter? And how can you utilize it in your own filmmaking? Are there generators out there that can help you to get this auditory effect? Let’s take a look at the Shepard tone and some Shepard tone generators.

Part 1: The Purpose of the Shepard Tone

The Shepard Tone has been used in a variety of films for many reasons, but the main purpose of it is that it creates tension.

In scenes that are already tense for one reason or another, adding the Shepard Tone to the score can really get people engaged and make them feel nervous or hypervigilant.

One of the most famous uses of the Shepard tone is in the film The Dark Knight. When the Bat-Pod is in use during chase scenes, the sound designer utilizes the Shepard tone to make it feel like the chase is never-ending.

It draws you in and keeps you on the edge of your seat while you wait for Batman to actually achieve his goal.

So, as a filmmaker, you want to be able to utilize the Shepard tone for your own purposes, correct? Let’s take a look at some Shepard tone generators and downloads you can try out.
