Your music stays yours.

No cloud dependencies or background telemetry. Audio processing runs 100% locally on your machine with offline license caching.

  • Six prime-timed reflections

    Carefully spaced, prime-numbered delays distribute reflections smoothly across the stereo field without resonant flutter.

  • 7 room environments

    Choose from Closet, Pantry, Hallway, Live Room, Club, Warehouse, and Arena geometries.

  • 8 surface materials

    Shape absorption with Heavy Fabric, Acoustic Tile, Wood, Plaster, Brick, Concrete, Plate Glass, or Metal.

  • Stereo return bus integration

    Outputs 100% reflections for precise send-level blend control in any modern DAW.

From our studio.
For your next move.

Calibrated and tested in Lit Factory NYC mixing sessions to seat drums, vocals, and instruments naturally in a 3D stereo acoustic environment without cluttering the frequency spectrum.

Prime Pro creates acoustic depth and stereo dimension using six carefully spaced, prime-numbered early reflections. Inspired by a classic studio recording technique attributed to Steve Albini, it brings the character of physical space into your mix—without conventional reverb tails. Choose from 7 room environments and 8 surface materials (56 acoustic combinations) that let you shape size, brightness, absorption, and character.

Audio Demonstrations

Hear It In Action

Hear the difference. Compare the original recording with the same performance processed through the plugin.

Featured Demonstrations

Vocal / Small vs Medium Room

Closet vs Live Room · Untreated Wood

44.1 kHz · 320 kbps

Demonstrates the acoustic difference between an intimate recording booth (Closet: 0.10x scale, 3–17 ms) and an open studio environment (Live Room: 1.00x scale, 29–107 ms).

0:000:00

Drums / Room Character

Hallway vs Warehouse · Untreated Wood

44.1 kHz · 320 kbps

Demonstrates reflection density and room shape around drum hits. Hallway (0.50x scale, 13–53 ms) delivers tight slap reflections; Warehouse (2.00x scale, 59–211 ms) spreads reflections across a wide stereo perimeter.

0:000:00

Guitar / Room Character

Pantry vs Club · Untreated Wood

44.1 kHz · 320 kbps

Contrasts acoustic boundaries around rhythmic guitar. Pantry (0.25x scale, 5–29 ms) tightens the instrument into a compact reflective space; Club (1.50x scale, 43–163 ms) introduces club-stage acoustic spread.

0:000:00

Synth / Room Scale

Live Room vs Arena · Untreated Wood

44.1 kHz · 320 kbps

Places electronic synthesizer textures inside physical acoustic spaces. Live Room adds tangible studio realism; Arena (4.00x scale, 113–431 ms) creates massive, stadium-sized prime reflection patterns.

0:000:00

Complete Seven-Room Tour

Audition the exact same dry drum performance across all seven calibrated acoustic room sizes. Switch freely between rooms during playback to hear the prime-number timing scale progression.

Acoustic Progression Through All Seven Rooms

Identical Drum Performance · Untreated Wood · Profile A Output Compensation

44.1 kHz · 320 kbps

Every room features a deterministic six-tap prime-number timing profile. Notice how the prime interval distribution avoids resonant comb-filtering peaks while scaling from intimate closet reflections to vast arena tails.

Material Comparison

Compare contrasting boundary absorption models in Live Room. Heavy Fabric rapidly damps high frequencies for an intimate, warm decay, while Plate Glass preserves high-frequency energy with bright, specular clarity.

Wall Absorption & Damping Contrast

Live Room (1.00x) · Heavy Fabric vs Plate Glass

44.1 kHz · 320 kbps

Both models process the identical dry drum performance with matched room geometry. Switch between absorptive Heavy Fabric and highly reflective Plate Glass to hear physical surface damping in action.
