Reverside is a sophisticated dual‑engine algorithmic reverb that combines Early and Late reflection processing into interlinked engines, each with independent diffusion, EQ, filtering, modulation and stereo/M‑S routing. Use it for believable spatialization, immersive staging or bold creative effects—from intimate close‑ups to wide cinematic placements.
The Early Reflection engine can host up to 200 reflections and lets you control virtual geometry with both relative and absolute dimension controls, shape, wall absorption, air‑induced decay, fill‑in and time‑warp parameters to create natural or artificial reflection patterns. The algorithm simulates sound propagation in 3D, so you can place source and listener anywhere in a virtual space to derive natural direct‑path timing and first‑reflection cues for coherent externalization and controllable distance and direction.
The Late Reflection engine delivers smooth long tails and strong envelopment. Twelve diffusion models and a non‑exponential FAT envelope let you sculpt onset and tail behavior. Frequency‑dependent decay profiles are set using a 3‑band filter whose band gains can be adjusted independently per channel, enabling asymmetric tonal and decay behaviors.
Both engines offer independent pre‑delays that can be set in milliseconds or tempo‑synced subdivisions, letting you create precise, rhythmic or spatial effects. Reverside uniquely supports setting many engine parameters independently per channel (L/R, M/S or anything between), enabling asymmetric tails, rotating perspectives and evolving spatial effects.
Reverside provides extensive internal modulation that preserves clarity and harmonic content. Each engine has its own modulation controls, and the interface exposes 100+ adjustable parameters for deep sound shaping without external tools.
FEATURES
- Multi‑engine architecture: interlinked Early and Late processing for flexible tonal and spatial shaping
- 3D source/listener placement: position and orient source and listener in virtual geometry for realistic timing and spatial cues
- Spatial FX: independent frequency‑dependent decay, reverb time and envelope profile per L/R or M/S channels for asymmetric and evolving stereo tails
- ER engine: up to 200 reflections, geometry controls (absolute/relative), shape, wall absorption, air decay, fill‑in and time‑warp
- LR engine: 12 diffusion models, FAT non‑exponential envelope, long smooth tails and envelopment control
- Per‑engine pre‑delay with time and tempo modes: ms or tempo‑synced subdivisions, absolute and relative timing options
- Spectral shaping: per‑reflection absorption, frequency‑dependent decay, 3‑band filters and multi‑band filtering/panning
- Bidirectional filter routing: ER→LR, LR→ER or ER|LR modes for different material/decay interactions
- Asymmetric parameter panning: split time‑domain and filter parameters between L/R or M/S for asymmetric decay and imaging
- Advanced imaging: mid/side/rotation control, width, decorrelation and spectral panning for rich, stable fields
- ER to LR routing with multiple pick‑up points for flexible signal flow
- Modulation: extensive, artifact‑free modulation with per‑engine settings
- Workflow & UI: param locks, A/B/C/D memory slots, preset management, customizable color schemes, fonts and skins, localization support
- GPU‑accelerated UI (OpenGL) for smooth rendering
Current version: 0.9.6.b480 — stable and production‑usable. The user interface is subject to redesign. The included factory preset library is small and intended for testing; it does not cover the plugin’s full capability.
