Audio Limiter
Keep every peak at or under a ceiling, reading the peaks between samples, so a clip can be made louder without clipping. The final stage of a master, before Audio Normalize or after it.

Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| audio | AUDIO | The clip to limit. | |
| gain_db | FLOAT | 0.00–24 | dB pushed into the limiter, which is how much louder the result gets. `0` = only catch overs; `6` = noticeably louder. |
| ceiling_db | FLOAT | -1.0-24–0 | Highest level let through. `-1` = safe for lossy encoding; `-0.3` = lossless delivery; `0` = full scale. |
| release_ms | FLOAT | 1001–2000 | Milliseconds the gain takes to recover. `20` = loud and dense; `100` = natural; `500` = transparent on sparse material. |
| lookahead_ms | FLOAT | 5.00.5–20 | Milliseconds the gain starts falling before a peak. `5` = clean; `1` = sharper transients, more distortion on bass. |
| true_peak | BOOLEAN | true | `true` = reads peaks between samples, four times oversampled, so the ceiling holds after encoding; `false` = sample peaks only. |
