Oli Larkin has released the Endless Series, four effect plugins based on an auditory illusion known as “Circular Pitch” or more commonly the “Shepard Tone/Scale” after Roger N. Shepard who discovered it in the 1960s.
Endless Series features
- Specify glissando or chromatic (stepped) mode
- Change the rate and direction of the tone/effect
- Adjust the base-pitch of the tone/effect
- Mix between two different amplitude envelopes
- Spread the partials across the stereo image
- Presets and manual included
Endless Tone can be used to synthesize classic Shepard/Risset tones. It can also be used as a ring modulator either using an internal sine wave or the audio input for the carrier signal.
Endless Flanger is a circular pitch (barber-pole) flanger – instead of flanging up and down the frequency spectrum, it appears to continuously flange in one direction.
Endless Phaser works in the same way but rather than using delay lines, it uses filters to produce its effect.
Endless Shifter provides a further variation by using pitch shifting to impose the illusion of circular pitch on the source material.
The Endless Series is available for Windows VST/RTAS and Mac VST/AU/RTAS UB and costs £15 GBP.
The plug-ins require Pluggo Runtime 3.61 or higher to run.
