What platforms does Lagrange support?

Lagrange is available on Windows, macOS.

What is Lagrange best for?

Lagrange is best for granular delay and texture generation (break audio into manipulable grain fragments), creating ambient soundscapes from any source (turn impacts into evolving layers), pitch-shifted grain effects (harmonies and dissonant textures from grain manipulation), abstract sound design and processing (otherworldly, unpredictable results), turning short sounds into evolving textures (stretch moments into atmospheres).

Lagrange (Free Granular Delay)

Name: Lagrange
Author: Ursa DSP

by Ursa DSP · Free Plugins

A unique stereo delay that produces otherworldly echoes using granular techniques, where each grain samples a different point in the delay buffer.

What it does

A free granular delay from Ursa DSP. Takes incoming audio, chops it into tiny grains, and plays them back with independent control over pitch, size, density, and position. The result is everything from subtle textural delays to completely abstract soundscapes.

The granular engine is the key — instead of just repeating a delayed copy, it breaks the audio into fragments and lets you manipulate how those fragments are arranged and played back. Pitch-shifting individual grains creates harmonies and dissonant textures that normal delays can't do.

Remarkably capable for a free plugin. Clean UI with real-time visualization of the grain activity.

Why it's useful for game dev

Extremely useful for game audio sound design. Turn any source into atmospheric textures — feed it a single impact and you get evolving ambient layers. Great for creating otherworldly environments, magical effects, and abstract soundscapes from concrete source material. The pitch manipulation creates alien vocal textures too.

Pros

+Free granular delay — rare at this quality
+Grain pitch, size, density, and position control
+Real-time grain visualization
+Goes from subtle to completely abstract
+Clean, modern UI

Cons

−Can be CPU-intensive with high grain density
−Granular processing has a learning curve
−Results can be unpredictable

Use Cases

Best suited for

•Granular delay and texture generation (break audio into manipulable grain fragments)
•Creating ambient soundscapes from any source (turn impacts into evolving layers)
•Pitch-shifted grain effects (harmonies and dissonant textures from grain manipulation)
•Abstract sound design and processing (otherworldly, unpredictable results)
•Turning short sounds into evolving textures (stretch moments into atmospheres)

Less suitable for

•Predictable, repeatable delay effects
•Simple echo and slapback needs
•Low-CPU processing chains with many instances
•Traditional tempo-synced rhythmic delays

Delay

An audio effect that records and plays back a signal after a set period of time.

PaulXStretch

Xenakios / Sonosaurus

Extreme time-stretching for ambient textures — different technique but similar ambient-from-anything results.

Valhalla Freq Echo

Valhalla DSP

Frequency-shifted delays for alien textures — more controlled than granular but still otherworldly.
