| audio | `audio` | The audio file to process. | `{"type":"audio","uri":"","asset_id":null,"data"...` |
| threshold_db | `float` | Threshold in dB above which the limiter is applied. | `-2` |
| release_ms | `float` | Release time in milliseconds. | `250` |
| auto_gain | `bool` | Apply automatic makeup gain so the limited peaks reach 0 dBFS, turning the headroom below the ceiling into added loudness (maximizer behaviour). | `true` |

## Outputs

| Output | Type | Description |
