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.

Local users

Make sure your ComfyUI is updated.

• Download ComfyUI
• Update Guide

Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated.

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

Cloud users

• Cloud 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.

Workflow

Stable Audio 1.0: Text to Audio

Generate audio from text prompts using Stable Audio.

Run on Comfy Cloud

Open in Comfy Cloud

Download Workflow

Download JSON or search “Stable Audio 1.0: Text to Audio” in Template Library

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

stable-audio-open-1.0.safetensors

2.3GB. Place in models/checkpoints/

Place the checkpoint in:

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

Text encoder

t5-base.safetensors

Text encoder for prompt conditioning. Place in models/text_encoders/

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.
