+# 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 |
