Make sure your ComfyUI is updated.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 If you can’t find them in the template, your ComfyUI may be outdated.If nodes are missing when loading a workflow, possible reasons: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
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. Related links:

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:

​
Text encoder
