Turn prompts into rich, realistic audio and music instantly.Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning - you still choose inputs, prompts, and settings.<h3 id="open-preloaded-workflow-on-runcomfy">Open preloaded workflow on RunComfy</h3><a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/stable-audio-3-0-medium-base-workflow-in-comfyui-text-to-audio?utm_source=civitai&amp;utm_medium=referral">Open preloaded workflow on RunComfy (browser)</a>Why RunComfy first - Fewer missing-node surprises - run the graph in a managed environment before you mirror it locally. - Quick GPU tryout - useful if your local VRAM or install time is the bottleneck. - Matches the published JSON - the zip follows the same runnable workflow you can open on RunComfy.When downloading for local ComfyUI makes sense - you want full control over models on disk, batch scripting, or offline runs.How to use (local ComfyUI) 1. Load inputs (images/video/audio) in the marked loader nodes. 2. Set prompts, resolution, and seeds; start with a short test run. 3. Export from the Save / Write nodes shown in the graph.Expectations - First run may pull large weights; cloud runs may require a free RunComfy account.<hr /><h3 id="overview">Overview</h3>With this official audio generation setup, you can turn text prompts into expressive, high-quality music and ambient audio. It supports extended playback, smooth tonal transitions, and flexible sound layering. Great for sound designers, musicians, or developers experimenting with text-to-audio generation. The workflow uses T5Gemma and Qwen3.5 encoders to enhance prompt accuracy and output quality. Its reproducible structure ensures consistent creative results for professional audio projects.Important nodes:<h2 id="key-nodes-in-comfyui-stable-audio-3.0-medium-base-workflow">Key nodes in Comfyui Stable Audio 3.0 Medium Base workflow</h2><ul><li><code>ComfySwitchNode</code> (#34). Toggles between the original <code>user_input</code> and the Qwen-generated text. Turn it on for structured, length-matched rewrites or off for direct control.</li><li><code>TextGenerate</code> (#28). Runs Qwen3.5 with a category-specific system prompt to expand ideas. To customize the rewrite style, edit the category templates in <code>JsonExtractString</code> (#49) and the glue prompts in the adjacent <code>Text Replace</code> nodes.</li><li><code>EmptyLatentAudio</code> (#11). Sets clip length. Keep this aligned with the inserted <code>AUDIO_LENGTH</code> token so the synthesis time matches the textual intent.</li><li><code>KSampler</code> (#3). Governs the denoising trajectory for Stable Audio 3. Adjust <code>seed</code> for variations while keeping other settings stable to compare takes fairly.</li><li><code>SaveAudioMP3</code> (#19). Controls the output filename prefix and format for quick library building from multiple runs.</li></ul><h3 id="notes">Notes</h3>Stable Audio 3.0 Medium Base workflow in ComfyUI | Text-to-Audio - see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/stable-audio-3-0-medium-base-workflow-in-comfyui-text-to-audio?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.
