# Stable Audio 1.0 ComfyUI workflow example

> Guide to using Stability AI's open-source Stable Audio 1.0 model in ComfyUI for text-to-audio generation.

<Tip>
  <Tabs>
    <Tab title="Portable or self deployed users">
      Make sure your ComfyUI is updated.

      * [Download ComfyUI](https://www.comfy.org/download)
      * [Update Guide](/installation/update_comfyui)

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated. (Desktop version's update will delay sometime)

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup
    </Tab>

    <Tab title="Desktop or Cloud users">
      * The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

**Stable Audio 1.0** is Stability AI's first open-source audio generation model. It takes a text prompt and generates an audio clip. In ComfyUI, it works like a standard text-to-audio pipeline: CLIP encodes the prompt, a KSampler denoises the latent, and the VAE decodes it to audio.

The workflow uses **standard ComfyUI nodes** — no custom nodes required. It loads the Stable Audio 1.0 checkpoint, encodes your prompt via a CLIP text encoder (t5-base), denoises the latent audio with a KSampler, and decodes it to audio through the model's VAE.

**How to use**:

1. **Load the checkpoint** — The `CheckpointLoaderSimple` node uses `stable-audio-open-1.0.safetensors`
2. **Write a prompt** — Enter your description in the `CLIPTextEncode` node (e.g. "heaven church electronic dance music")
3. **Set duration** — Adjust the `EmptyLatentAudio` node's length value (default 47.6 seconds)
4. Click **Run** (`Ctrl/Cmd + Enter`) to generate. The audio will be saved to `ComfyUI/output/audio/`

## Model download

When loading the workflow, ComfyUI will prompt you with download links for any missing models. To set up manually, download the files below and place them in the correct folders.

### Checkpoint

<Card title="stable-audio-open-1.0.safetensors" icon="download" href="https://huggingface.co/StabilityAI/stable-audio-open-1.0/resolve/main/stable-audio-open-1.0.safetensors">
  2.3GB. Place in models/checkpoints/
</Card>

Place the checkpoint in:

```
📂 ComfyUI/
├── 📂 models/
│   └── 📂 checkpoints/
│       └── stable-audio-open-1.0.safetensors
```

### Text encoder

<Card title="t5-base.safetensors" icon="download" href="https://huggingface.co/Comfy-Org/t5-base/resolve/main/t5-base.safetensors">
  Text encoder for prompt conditioning. Place in models/text\_encoders/
</Card>

Place the text encoder in:

```
📂 ComfyUI/
├── 📂 models/
│   └── 📂 text_encoders/
│       └── t5-base.safetensors
```

After placing the files, press **R** in ComfyUI to refresh nodes and load the latest models.
