# Remaster

> Remaster an existing Suno clip with a newer model and quality sliders. See supported inputs, parameters, pricing, response fields, and API examples.

Re-render an existing clip through Suno's remaster model. The song stays the same; production quality, tone, and stereo image are refreshed. Each request returns a pair of remastered clips.

## Model

```
suno-ai/remaster
```
