DrawVerb

DrawVerb

A reverb you design, not adjust.

DrawVerb is a reverb where you design the space instead of dialing in abstract knobs. You draw the walls of a room in 2D, give each wall a material, place a sound source and a listener inside, and DrawVerb simulates how sound behaves in that space and turns it into a reverb.

The room you draw is the reverb. The engine accounts for the real physics of the space:

• Room shape and size. The geometry drives the sound. Changing the shape of the room can have a big impact on how fast the tail decays.
• Wall materials. Each material (concrete, glass, wood, plaster, marble, carpet, curtains and more) reflects and absorbs different frequencies the way the real material would.
• Source and listener placement. Distance and angle between them shape the early reflections, and you can aim the listener's head.
• Air absorption. Air eats high frequencies over distance, so bigger spaces naturally get darker.
• Speed of sound. Adjustable, and raising it lowers the decay time.

All of that gets rendered into a stereo impulse response that the plugin convolves in real time, so the reverb stays responsive while you move things around.

Two quality modes. High is the detailed, most physically accurate mode and runs on your GPU using your system's native graphics API (Direct3D on Windows, Metal on macOS, selected automatically). Low is a lighter approximation that captures the character of your room and runs on any machine.

Controls:

• Damping. How much high end the air absorbs over distance. Higher darkens the tail.
• Body. Weight and warmth of the late tail. Up for fuller and darker, down for lighter and more transparent.
• Phase (High only). Adds the natural resonances a real room gets from its shape and size. Off is the smoothest and most musical, Hybrid applies it to the early reflections only, Pure is the most realistic.
• Direct sound. Folds the straight source-to-listener path into the wet signal, with the same air roll-off as the reflections.
• Binaural. Head-aware processing for an immersive image on headphones.
• Plus the usual mix tools: pre-delay, dry and wet, high and low shelves, and a modulation section.

Factory presets (small, medium and big rooms, plus huge halls) give you starting points, and you can edit everything from there.
