# Noise validator

> The Onepin Noise validator (validator_noise) — scores generated audio for clarity on a 0–100 scale, flagging background noise and artifacts, and retries lines below the threshold.

**Family: Validator · `type: validator_noise`**

The Noise validator answers: **is it clean?** It flags background noise and artifacts in each generated line, scoring clarity on a 0–100 scale where higher is cleaner. Lines below the bar are retried; lines at or above it pass.

## Config

| Config key    | Default | Range                                           |
| ------------- | ------- | ----------------------------------------------- |
| `threshold`   | `70`    | 0–100 (clarity score required to pass)          |
| `max_retries` | `3`     | 1–50 (regeneration attempts for a failing line) |

```python
node["config"] = {"threshold": 70.0, "max_retries": 3}
```
