# Noise Reduction
|
||
|
|
|
||
|
|
Reduce background noise in an audio file using FFT-based denoising with selectable strength.
|
||
|
|
|
||
|
|
## API Endpoint
|
||
|
|
|
||
|
|
`POST /api/v1/tools/noise-reduction`
|
||
|
|
|
||
|
|
Accepts multipart form data with an audio file and a JSON `settings` field.
|
||
|
|
|
||
|
|
## Parameters
|

|
|
|
||
|
|
| Parameter | Type | Required | Default | Description |
|
||
|
|
|-----------|------|----------|---------|-------------|
|
||
|
|
| strength | string | No | `"medium"` | Denoising strength: `light`, `medium`, `strong` |
|
||
|
|
|
||
|
|
## Example Request
|
||
|
|
|
||
|
|
```bash
|
||
|
|
curl -X POST http://localhost:1349/api/v1/tools/noise-reduction \
|
||
|
|
-H "Authorization: Bearer si_your-api-key" \
|
||
|
|
-F "file=@audio.mp3" \
|
||
|
|
-F 'settings={"strength": "strong"}'
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example Response
|
||
|
|
|
||

```json
|
||
|
|
{
|
||
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
||
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.mp3",
|
||
|
|
"originalSize": 4500000,
|
||
|
|
"processedSize": 4500000
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
|
||
|
|
- `light` preserves more detail but removes less noise. `strong` removes more noise but may introduce subtle artifacts.
|
||
|
|
- Best results on recordings with consistent background noise (fan hum, air conditioning, static).
|
||
|
|
- Output format matches the input format.
