Eternal Reverb

Draw the room.
Shape the tail.

A lush everyday reverb, plus spaces you draw yourself. Connect rooms with doorways, move the sound through them in time, and shape how every tail evolves.

Eternal Reverb’s Space page with the Felt Room preset and the tail envelope preview — Space: six modes, with the tail envelope at a glance.

Eternal Reverb’s Space Map with two rooms joined by a doorway and the listener’s path — Space Map: draw rooms, join them with doorways, move the sound through them.

Eternal Reverb’s Space Map side view with two stacked rooms joined by a vertical opening — Side view: stack rooms and set heights.

Eternal Reverb’s tail timeline with drawn curves for brightness, width, shimmer, modulation and density — Tail timeline: shape how the tail changes from start to finish.

Eternal Reverb’s Harmony page tuned to D Dorian with a fifth up — Harmony: tune the tail to your key and scale.

Eternal Reverb’s Shimmer view with octave up and down — Shimmer: octaves up, down or both.

Eternal Reverb’s Reverse view with per-note reverse on — Reverse: tails that build backwards into each note.

Eternal Reverb’s Freeze view, frozen and synced to one bar — Freeze: hold the tail for a bar, or forever.

Six spaces

Room, Hall, Plate, Chamber, Spring, and Ambience, with early/late balance, diffusion, density, chorus, saturation, and 64 factory presets.

Space Map

Draw up to three rooms, choose their materials, and join them with doorways. Stack them, then move the source and listener along paths in time with your song.

Tail timeline

Draw how brightness, width, shimmer, modulation, and density change across the tail, with adjustable Bloom and Reverse.

Tuned and under control

Harmony and shimmer that follow your key, band decay, pre and post EQ, Mid/Side decay, ducking, and Freeze that holds as long as you choose.
