Reverbs
Reverbs simulate acoustic spaces by creating many delayed, filtered reflections. Different algorithms offer different sonic characteristics.

freeverb
Freeverb - Classic Schroeder-style algorithmic reverb.
| Param | Type | Default | Description |
|---|---|---|---|
| in | signal | - | Input signal |
| room | number | 0.5 | Room size (0-1) |
| damp | number | 0.5 | High frequency damping (0-1) |
| room_scale | number | 0.28 | Density factor (affects comb filter feedback) |
| room_offset | number | 0.7 | Decay baseline offset |
Aliases: reverb
A classic reverb algorithm with a smooth, natural sound. Higher room values create larger spaces with longer decay. The advanced room_scale and room_offset parameters let you tune the reverb character.
// Medium room reverb
osc("saw", 220) * ar(trigger(2)) |> freeverb(%, 0.5, 0.5) |> out(%, %)// Large hall
osc("saw", 110) * ar(trigger(1)) |> freeverb(%, 0.9, 0.3) |> out(%, %)// Damped small room
osc("noise") * ar(trigger(4), 0.001, 0.05) |> freeverb(%, 0.2, 0.8) |> out(%, %)// Custom room character (more density, longer baseline decay)
osc("saw", 220) * ar(trigger(2)) |> freeverb(%, 0.5, 0.5, 0.35, 0.8) |> out(%, %)dattorro
Dattorro Reverb - High-quality plate reverb algorithm.
| Param | Type | Default | Description |
|---|---|---|---|
| in | signal | - | Input signal |
| decay | number | 0.7 | Decay time (0-1) |
| predelay | number | 20.0 | Predelay in milliseconds |
| in_diff | number | 0.75 | Input diffusion (smears input transients) |
| dec_diff | number | 0.625 | Decay diffusion (smooths reverb tail) |
Aliases: plate
The Dattorro plate reverb produces lush, shimmering tails perfect for vocals and synth pads. The predelay separates the dry signal from the reverb onset. The diffusion parameters control how quickly transients are smeared.
// Lush plate reverb
osc("saw", 220) * ar(trigger(2)) |> dattorro(%, 0.8, 30) |> out(%, %)// Short bright plate
osc("tri", 440) * ar(trigger(4)) |> dattorro(%, 0.5, 10) |> out(%, %)// High diffusion for pad-like washes
osc("saw", 220) * ar(trigger(2)) |> dattorro(%, 0.9, 50, 0.9, 0.8) |> out(%, %)fdn
FDN Reverb - Feedback Delay Network reverb.
| Param | Type | Default | Description |
|---|---|---|---|
| in | signal | - | Input signal |
| decay | number | 0.8 | Decay time (0-1) |
| damp | number | 0.3 | High frequency damping (0-1) |
Aliases: room
A matrix-based reverb using multiple delay lines with cross-feedback. Creates dense, even decay patterns suitable for ambient textures.
// Dense ambient reverb
osc("saw", 55) * ar(trigger(0.5)) |> fdn(%, 0.9, 0.4) |> out(%, %)// Tight room
osc("noise") * ar(trigger(8), 0.001, 0.02) |> fdn(%, 0.4, 0.6) |> out(%, %)
