# Suno API: Sounds Generate
> Generate sound effects, ambience, and loopable audio from text prompts.
### Important Notes
* Supports `v5` and `v5.5`
* `prompt` is required and should clearly describe the target sound effect
* `sound_loop` can be enabled for ambient beds, UI sounds, and other repeatable effects
* `sound_tempo` and `sound_key` are optional controls for more structured sound design
* `grab_lyrics` can be enabled when you want lyric-style subtitle metadata if available
### Usage Scenarios
* 🔔 Product/application prompt tone
* 🎮 Game/interactive scene ambient loop sound
* 🎞️ Short video / Advertisement / Video transition sound effects
### Generate Sound Effects
Create non-music audio such as ambience, impacts, transitions, UI sounds, and loopable effects from a text prompt.
```json basic sound effect theme={null} theme={null}
{
"model": "suno/sounds-generate",
"callback_url": "",
"input": {
"model": "v5.5",
"prompt": "Heavy rain hitting a car roof with distant thunder and occasional windshield wiper movement."
}
}
```
```json loopable ambience theme={null} theme={null}
{
"model": "suno/sounds-generate",
"callback_url": "",
"input": {
"model": "v5",
"prompt": "Retro arcade room ambience with soft machine hums, coin sounds, and subtle electronic beeps.",
"sound_loop": true,
"sound_tempo": 110,
"sound_key": "Cm",
"grab_lyrics": false
}
}
```
