|
|
| ## 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 |
|
|
| ## Model Info |
|
|
| Based on [AudioSR: Versatile Audio Super-Resolution](https://arxiv.org/abs/2309.07314) by Haohe Liu et al. |
