FRCTL has introduced a new audio effect plugin that runs a selection of parallel DSP characters to add depth, space, and motion to any sound.
Instead of stacking separate chorus, reverb, tremolo, and saturation plugins, SWRL blends 6 effects (characters) into one cohesive signal chain that runs together.
Every sound in your project is sitting still. SWRL fixes that. Six distinct motion effects — chorus, spatial rotation, tremolo, diffusion reverb, rhythmic pump, and warm saturation — each with its own fader. Blend them however you want. Shape the result with built-in crossover protection, output filters, and a spectrum analyzer. No effect chain stacking. No menu diving. Just faders and movement.
SWRL features
- Individual amount control per character.
- Adjustable rate and stereo width.
- Crossover filters (HP/LP).
- Built-in spectrum analyzer.
- Reactive visualization.
- Automatic gain compensation.
Priced $19.99 USD, SWRL is available for macOS, Windows and Linux in VST3, AU, and CLAP plugin formats. Available for free, SWRL Lite uses the same engine simplified to 2 controls (Amount and Mix) driving all 6 characters at once.
