Delirion
Key Features
- Splits the Doppler-based effect across independent low, middle, and high frequency bands
- Lets each band use its own speed and cutoff settings for focused tonal movement
- Uses Odd and Even channel controls to create asymmetric stereo motion from a stereo source
- Links Doppler instances when a more grounded low-frequency image is wanted
- Adds Invert, Freeze, and Sync modifiers for directional shifts, held washes, and timed drift
- Blends Bottom-band wave shaping and a global dry/wet control for extra weight without losing the source
- Makes every parameter available to host automation for evolving sound-design moves
Description
Delirion is a three-band Doppler shifter for turning sustained, harmonically rich material into anything from restrained chorus movement to unstable pitch-smearing and microtonal textures. Its low, middle, and high sections work independently, so you can treat a full sound evenly or let one part of the spectrum do the unsettling work.
Each band has separate speed and cutoff control, with Odd/Even channel settings for asymmetrical stereo motion. Linking the instances is useful when you want to keep the low end more centered, while independent settings can make pads, guitars, electric keys, and vocals feel wider and less predictable.
Invert changes the direction of the Doppler shift, Freeze captures the middle band into a repeating wash, and Sync keeps the inverted effect aligned with the source. A Bottom control adds wave shaping to the lower band, while the main Mix dial lets the processed signal support the original rather than erase it.
This is a character effect rather than a transparent corrective chorus: it rewards slow, sustained sources and parameter automation. Start with a modest wet mix and linked low band for musical width, then separate the bands or engage Freeze when a part needs a deliberately strange, moving layer.
Frequently Asked Questions
What kind of effect is Delirion?
Delirion is a Doppler-based modulation effect with three independently controlled frequency bands. It can produce gentle chorus-like width, but it is designed to reach more pronounced detune, pitch movement, and experimental textures as the bands are pushed apart.
Which sounds work best with Delirion?
The developer recommends harmonically rich, sustained sources. Pads, held guitar chords, electric keys, vocals, and long sound-design tails leave enough material for the Doppler motion and the middle-band Freeze function to become audible.
What do Invert, Freeze, and Sync do?
Invert changes the direction of the Doppler shift. Freeze holds the middle frequency band as a repeating diffuse wash, while Sync is available with the inverted signal to keep its drift timed to the input.
Does Delirion include separate controls for a stereo signal?
Yes. The Odd and Even controls set Doppler speed per channel on multichannel material, corresponding to left and right on a stereo signal. The Link control can instead make the sections follow the odd-channel speed, which is often useful for keeping bass energy more centered.
