Reverb
Governed by: docs/design/specs/2026-07-15-plugin-catalog-tiered-packaging.md
58 plugins, 22 of them cleared to run on the console's own audio thread. Figures are at 96 kHz; the columns are explained on the catalog index. Sorted by hosting verdict, then by name.
5 of them declare no LV2 category at all and are filed here from their own name or description — our reading, not the plugin's claim.

| MDA Ambience | lv2-mdala-plugins | suitable | 0 ms | zero | 0.04 % | ok / ok / ok / ok | yes | |
| MV | lv2-airwindows | suitable | 0 ms | zero | 0.54 % | ok / ok / ok / ok | yes | Extra — huge 'MV' reverb: effectively 100 % wet at defaults (dry -89.9 dBFS), 111 ms wet onset, builds for 760 ms and is still -16.6 dB re peak at 1 s. |
| PocketVerbs | lv2-airwindows | suitable | 0 ms | zero | 1.55 % | ok / ok / ok / ok | yes | Extra — multi-type small reverb (room/chamber/spring…); tails decay, but the default Room is very short and it is the dearest live-tier reverb here after Reverb. |
| StarChild | lv2-airwindows | suitable | 0 ms | zero | 0.85 % | ok / ok / ok / ok | yes | Extra — comb/space effect praised by the community but reported to cause xruns on MOD hardware with sustain past noon; 0.86 % of a core here. |
| Verbity | lv2-airwindows | suitable | 0 ms | zero | 0.28 % | ok / ok / ok / ok | yes | Recommended — the author's starter-kit reverb and the cheapest usable one here (0.29 % of a core): dry at 0 ms, a 27 ms wet onset at defaults and a clean decay (-51 dB re peak at 200 ms, -99 dB at 1 s). |
| kCosmos | lv2-airwindows | suitable | 0 ms | zero | 0.48 % | ok / ok / ok / ok | yes | Extra — kCosmos reverb/ambience, research standout but not run through the tail oracle here. |
| kGuitarHall2 | lv2-airwindows | suitable | 0 ms | zero | 0.40 % | ok / ok / ok / ok | yes | Extra — guitar-hall reverb. |
| kPlateA | lv2-airwindows | suitable | 0 ms | zero | 0.61 % | ok / ok / ok / ok | yes | Recommended — plate reverb with a clean, decaying tail: dry at 0 ms, wet onset 4.3 ms at defaults (wetness=0.25), -50 dB re peak at 200 ms and -110 dB at 2 s. |
| kPlateB | lv2-airwindows | suitable | 0 ms | zero | 0.63 % | ok / ok / ok / ok | yes | Extra — kPlate variant B; not run through the tail oracle (kPlateA was). |
| kPlateC | lv2-airwindows | suitable | 0 ms | zero | 0.62 % | ok / ok / ok / ok | yes | Extra — kPlate variant C; not oracle-characterised. |
| kPlateD | lv2-airwindows | suitable | 0 ms | zero | 0.72 % | ok / ok / ok / ok | yes | Extra — kPlate variant D; not oracle-characterised. |
| BrightAmbience3 | lv2-airwindows | conditional — its latency changes with its own controls | 0 ms | zero | 0.29 % | ok / ok / ok / ok | yes | Extra — bright ambience v3. |
| Classic Reverb RE-02 | lv2-classicreverb-re02 | conditional — its latency changes with its own controls | 0 ms | zero | 0.46 % | ok / ok / ok / ok | yes | Classic Reverb RE-02 (AnClark, AI-assisted reverse-engineering of Kjaerhus Classic). |
| Infinity | lv2-airwindows | conditional — its latency changes with its own controls | 15.906 ms | high | 0.48 % | ok / ok / ok / ok | yes | Studio, not recommended: an infinite-hold reverb by design (feedback infinite at defaults) — the tail does not decay and a sustained tone holds at -11..-16 dBFS. |
| Infinity2 | lv2-airwindows | conditional — its latency changes with its own controls | 12.604 ms | high | 0.53 % | ok / ok / ok / ok | yes | Studio, not recommended: at defaults (feedback=1) it raises a sustained -6 dBFS sine to +3.9 dBFS peak within a second and holds there. |

| Galactic | lv2-airwindows | unknown — reports a latency it does not keep | 94.375 ms | high | 0.40 % | ok / ok / ok / ok | yes | Studio, not recommended for the live desk: 100 %-wet by default with a 95.7 ms wet onset and a tail still -32 dB re peak at 2 s; the v34.0 build also lacks the 2026-08-24 right-channel dither fix. |

| CloudReverb | lv2-cloudreverb | unsuitable — costs more of a core than one insert may | 0 ms | zero | 3.06 % | — / — / — / — | no | Extra, not a default pick. |
| Dragonfly Early Reflections | lv2-dragonfly-reverb | unsuitable — allocates, locks or calls the system inside the audio callback | 0 ms | zero | 0.29 % | ok / ok / ok / ok | no | Dragonfly Early Reflections — an early-reflections-only processor, NOT a reverb with a tail: at 20 m the reflections span 8.6-162 ms and are gone by 200 ms (-114 dB), so it fails the generic reverb oracle by design, not by fault. |
| Dragonfly Hall Reverb | lv2-dragonfly-reverb | unsuitable — allocates, locks or calls the system inside the audio callback | 0 ms | zero | 1.57 % | ok / ok / ok / ok | no | Dragonfly Hall — the live-tier hall. |
| Dragonfly Plate Reverb | lv2-dragonfly-reverb | unsuitable — allocates, locks or calls the system inside the audio callback | 0 ms | zero | 0.24 % | ok / ok / ok / ok | no | Dragonfly Plate — a plate reverb, and the cheapest reverb in the package: 0.24 % of a core per instance at 96 kHz (411/core), 0 ms dry-path latency at all four rates, flat cost in silence and exact-zero idle output. |
| Dragonfly Room Reverb | lv2-dragonfly-reverb | unsuitable — allocates, locks or calls the system inside the audio callback | 0 ms | zero | 1.53 % | ok / ok / ok / ok | no | Dragonfly Room — a live-tier room/ambience reverb. |

| KlangFalter | DISTRHO-Ports | unsuitable — needs a host facility the audio thread will not become | 0 ms | zero | 0.06 % | ok / ok / ok / ok | no | |
| MatrixVerb | lv2-airwindows | unsuitable — costs more of a core than one insert may | 25.719 ms | high | 7.20 % | ok / ok / ok / dies | no | Studio, not recommended: 51.3 ms wet onset at 100 % wet with no latency port, a tail that does not decay within 2 s, and the family's second-dearest plugin (7.3 % of a core per instance at 96 k). |
| Reverb | lv2-airwindows | unsuitable — costs more of a core than one insert may | 0 ms | zero | 6.09 % | ok / ok / ok / dies | no | Extra — the plain 'Reverb': a clean decaying tail, but 7.1 % of a core per instance at 96 k, the family's third-dearest plugin. |
| Tal-Reverb | DISTRHO-Ports | unsuitable — allocates, locks or calls the system inside the audio callback | 0 ms | zero | 1.58 % | ok / ok / ok / ok | no | |
