# AudioX Models (Safetensors)

`.safetensors` conversions of [AudioX-MAF](https://huggingface.co/HKUSTAudio/AudioX-MAF) model checkpoints for use with [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA).

AudioX is a unified anything-to-audio model from ICLR 2026 that supports text-to-audio, text-to-music, video-to-audio, and audio inpainting.

## Models

| File | Description | Size |
|------|-------------|------|
| `model.safetensors` | AudioX-MAF DiT model (full precision) | 5.19 GB |
| `synchformer_state_dict.safetensors` | Synchformer temporal encoder (shared with MMAudio) | 475 MB |
| `config.json` | Model architecture configuration | 3.3 KB |

## Sources

All models were downloaded from their **original sources** and converted by us:

- **AudioX-MAF**: [HKUSTAudio/AudioX-MAF](https://huggingface.co/HKUSTAudio/AudioX-MAF)
- **Synchformer**: Shared with [MMAudio](https://huggingface.co/hkchengrex/MMAudio)

## Usage

These models are automatically downloaded by the `generate_music` and `audio_inpaint` skills in ComfyUI-FFMPEGA. No manual setup needed.

**Manual installation:**
```
ComfyUI/models/audiox/
├── model.safetensors
├── synchformer_state_dict.safetensors
└── config.json
```

> **Note:** The `synchformer_state_dict.safetensors` is shared with MMAudio. If you already have it in `ComfyUI/models/mmaudio/`, AudioX will reuse it automatically — no duplicate download needed.

## Capabilities

| Skill | Description |
|-------|-------------|
| `generate_music` | Text-to-music and video-to-music generation |
| `audio_inpaint` | Fill gaps, extend, or regenerate sections of audio |
