Generates speech, music, and sound effects from one prompt across Magnific's Voice Generator, MCP, and Spaces.

Magnific has added Seed Audio 1.0, ByteDance's all-in-one audio model, letting creators generate voice, music, and sound effects from a single prompt.

## One prompt, a full sound scene

Traditional text-to-speech tools only give you a spoken line. Seed Audio 1.0 goes further, producing an entire soundscape in a single pass: natural human speech, original background music, foley-style sound effects, and environmental ambience, all from one instruction. Announced by ByteDance Seed on June 23, 2026 at the Volcano Engine FORCE conference, the model treats audio as a finished scene rather than a series of isolated voice clips, which makes it a natural fit for video, podcast, and game workflows where the whole mix matters.

## Scene control and multi-character dialogue

Inside Magnific, Seed Audio exposes granular scene control — you can direct the environment, the voice, the emotion, the background music, and the SFX independently. Because the model generates multi-character dialogue in a single pass, each speaker keeps a distinct voice, emotion, and native accent, so you can script an exchange between two or three characters without stitching separate renders together. Emotional delivery and cross-lingual synthesis come built in, so a line can shift tone or language without fine-tuning.

## Text, reference audio, or an image as your guide

Seed Audio can be steered three ways. The simplest is a plain text prompt describing the scene you want. For tighter control, you can attach up to three short reference audio clips — useful for zero-shot voice cloning or matching a specific timbre — or supply a single reference image that informs the delivery and mood. This flexibility lets creators move from a rough idea to a polished, on-brand track without leaving the Magnific canvas.

## Where you can use it on Magnific

Magnific has wired Seed Audio 1.0 into three surfaces: the Magnific Voice Generator for interactive creation, the MCP for programmatic and agent-driven pipelines, and Spaces for collaborative projects. That means the same model powering multi-speaker dialogue and full-scene audio is available whether you are experimenting by hand, calling it from a workflow, or building alongside a team. For an all-in-one creative platform that already spans image and video generation plus the original Magnific upscaler, adding a scene-aware audio model closes an obvious gap in the production stack.
