This ComfyUI workflow turns a single text prompt into a complete audio scene—speech, dialogue, background music, and sound effects—in one pass. It centers on the ByteDanceSeedAudio node (Seed Audio 1.0, text-only), which interprets your description to synthesize multi-speaker audio up to roughly two minutes without any reference audio. The MarkdownNote node in the graph provides on-canvas guidance, and SaveAudioAdvanced handles exporting the generated waveform to disk.
Technically, the ByteDanceSeedAudio node takes a natural-language prompt and conditions a generative audio model to produce a mixed-down waveform containing voices and non-speech elements guided by your instructions (e.g., voice qualities, emotions, ambience, music genre, and timing cues). In ComfyUI, the node outputs an audio object that flows directly into SaveAudioAdvanced, where you set output folder, file name pattern, and format. The result is an end-to-end text-to-audio pipeline that’s fast to iterate: refine the prompt, re-run, and compare versions until the scene sounds right.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
