Endless Series 2

Four audio effect plug-ins based on the auditory illusion known as Circular Pitch or more commonly the Shepard Tone/Scale after Roger N. Shepard who discovered it in the 1960s. Shepard showed that using basic additive synthesis its possible to create the illusion of a continuously rising or descending chromatic scale. The term circular pitch was used because, although the scale sounds as if it is moving in one direction, in fact, after twelve steps it returns to where it started.
