## Usage |
|
|
|
|
|
### Installation |
|
|
|
|
|
1. Install [ComfyUI-AudioSR](https://github.com/Saganaki22/ComfyUI-AudioSR) via ComfyUI Manager |
|
|
2. Download model(s) from this repository |
|
|
3. Place in `ComfyUI/models/AudioSR/` |
|
|
|
|
|
### Quick Start |
|
|
|
|
|
``` |
|
|
ComfyUI Workflow: |
|
|
Load Audio → AudioSR → Preview/Save Audio |
|
|
``` |
|
|
|
|
|
**Recommended Settings:** |
|
|
- Steps: 50-100 |
|
|
- Guidance Scale: 3.5-5.0 |
|
|
- Model: Use `audiosr_speech_fp32.safetensors` for voice, `audiosr_basic_fp32.safetensors` for everything else |
|
|
|
|
|
## What it does |
|
|
|
|
|
AudioSR upscales low-quality audio to high-quality 48kHz output using latent diffusion. It: |
|
|
|
|
|
- Resamples to 48kHz |
|
|
- Enhances high frequencies |
|
|
- Reduces compression artifacts |
|
|
- Adds clarity and detail |
|
