Demo summary

The creator demonstrates how to access the Stable Audio 3.0 workflow via ComfyUI templates, download the necessary checkpoint and text encoder models, and navigate the prompt nodes for music and sound effect generation.

Step-by-step

Update ComfyUI to the latest version
Open Comfy templates and select the Stable Audio Open 1.0 Medium model workflow
Click the download buttons on the right side of the interface to acquire the checkpoint and two text encoders
Move the checkpoint file into the checkpoints folder and the text encoders into the text encoder folder
Configure the duration and seed in the prompt node
Select the appropriate category for your generation, such as music, instrument, or sound effect
Run the workflow to generate and save the MP3

Options

Swap the standard VAE decode for a tiled audio decoder if you encounter issues

Watch out for

You must update ComfyUI to the latest version to access the templates
The workflow requires three specific models: one checkpoint and two text encoders

Tips

Use the 'music' category if you are trying to generate a full ensemble
Use the 'instrument' category if you only want to generate a single instrument
