Phonon
Your precision granular laboratory for sonic alchemy
With sub-sample precision and audio-rate modulation, Phonon transforms any source into a spectrum of new sound - from vaporised textures and dark drones to sharp, machine-funk beats.

Feature Summary
From surgical time-stretching to total sample destruction, turn any sound into a playable, expressive synth
- Granular Engine: Eight voices and sub-sample precision bridge the gap between classic textures and sharp “graintable” synthesis
- Effects: Shape your sound with a character-driven signal chain, from saturating drive to resonant filtering and a utility reverb for glue or depth
- Modulation: Drag-and-drop, flexible, audio-rate modulation matrix with unique sources like metadata and noise flavours
- Presets: Easily capture, export, evolve and share your sonic creations with sample embedding and eight-way snapshots.
Phonon provides a drag and drop workflow in a resizable interface, for ease of use as a standalone instrument or plugin-based production in the DAW of your choice.
