Delay
Governed by: docs/design/specs/2026-07-15-plugin-catalog-tiered-packaging.md
49 plugins, 29 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.
3 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.
| Plugin | Package | Host | Latency at 96 kHz | Class | Cost at 96 kHz | 44.1 / 48 / 96 / 192 | Certified | Note |
|---|---|---|---|---|---|---|---|---|
| ADT | lv2-airwindows | suitable | 0 ms | zero | 0.38 % | ok / ok / ok / ok | yes | Extra — artificial double tracking (short stereo delays). |
| Allpass delay line, cubic spline interpolation | lv2-swh-plugins | suitable | 0.010 ms | low | 0.10 % | ok / ok / ok / ok | yes | |
| Allpass delay line, noninterpolating | lv2-swh-plugins | suitable | 0 ms | zero | 0.05 % | ok / ok / ok / ok | yes | |
| Comb delay line, cubic spline interpolation | lv2-swh-plugins | suitable | 0.010 ms | low | 0.10 % | ok / ok / ok / ok | yes | |
| Comb delay line, linear interpolation | lv2-swh-plugins | suitable | 0.010 ms | low | 0.06 % | ok / ok / ok / ok | yes | |
| Comb delay line, noninterpolating | lv2-swh-plugins | suitable | 0 ms | zero | 0.05 % | ok / ok / ok / ok | yes | |
| Doublelay | lv2-airwindows | suitable | 0 ms | zero | 0.42 % | ok / ok / ok / ok | yes | Extra — dual delay/doubler, proven to delay, but the 0..1 delay controls map non-linearly (0.1 -> 100.9 ms, 0.2 -> 245.7 ms) with no unit, which is awkward on a desk. |

| GxEcho-Stereo | lv2-guitarix-plugins | suitable | 0 ms | zero | 0.07 % | ok / ok / ok / ok | yes | |

| LSP Delay Compensator Stereo | lsp-plugins-lv2 | suitable | 0 ms | zero | 0.03 % | ok / ok / ok / ok | yes | |
| LSP Delay Compensator x2 Stereo | lsp-plugins-lv2 | suitable | 0 ms | zero | 0.03 % | ok / ok / ok / ok | yes | |

| SampleDelay | lv2-airwindows | suitable | 0 ms | zero | 0.19 % | ok / ok / ok / ok | yes | Extra — sample/ms delay proven exact (10.000 ms set -> 480 frames at 48 k), but its Inv/Wet control runs 0..1 where upstream is -1..1 (kept deliberately for presets). |
| Simple delay line, cubic spline interpolation | lv2-swh-plugins | suitable | 0.010 ms | low | 0.03 % | ok / ok / ok / ok | yes | |
| Simple delay line, linear interpolation | lv2-swh-plugins | suitable | 0.021 ms | low | 0.03 % | ok / ok / ok / ok | yes | |
