New Shepard Tone Synth For Windows, Mac

Oli Larkin has introduced Endless Series v3 – a Shepard Tone synthesizer for Windows & Mac.

If you’re not familiar with Shepard Tones, they are basically an auditory illusion created by fading out one rising pitch while fading in another, starting at a lower pitch. The result is a sound that appears to be infinitely rising. The same effect can also be created with descending tones.

The above video offers an introduction to Shepard tones.
