The Endless Series are three plugins based on the auditory illusion known as Circular Pitch (or more commonly the Shepard/Risset tone). Circular pitch means a sound that appears to be constantly ascending or descending but ultimately
doesn’t seem to get any higher or lower (it returns to where it started).
Endless Flanger is like a traditional flanger except that instead of flanging
up and then down, it appears to continuously flange in one direction. Endless
Phaser works in the same way but instead of using delay lines it uses filters
to produce its effect.
Endless Tone can be used to generate classic Shepard/Risset tones. It also
can be used as a ring modulator either with an internal (sine wave) carrier
or using the audio input. Endless Tone is a free plugin.
