Exploring the Shepard Tone

The video explores auditory illusions, focusing on the Shepard Tone, an audio effect that creates the illusion of a continuously rising pitch. Invented by Roger Shepard in 1964, this effect uses psychoacoustics to manipulate sound perception. The Shepard Tone consists of a series of tones separated by octaves, with varying volumes that trick the listener into perceiving an endless rise. This effect is used in music and can evoke feelings of movement or unease. The video concludes with a brief mention of the complexity of brain activity involved in processing such auditory illusions.
