Seed Audio 1.0
Create dialogue, expressive voices, ambience, music, and sou
Seed Audio 1.0 is ByteDance Seed’s all-in-one AI audio generation model for complete sound scenes. From a single text (or multimodal) prompt, it creates multi-speaker dialogue with emotional delivery and natural accents, plus matching ambience, background music, and foley-style effects—ready for video, ads, podcasts, games, and more. Supports optional reference audio/image, up to 2-minute generations, and API access.
Features
- One-prompt generation of complete sound scenes: multi-speaker dialogue + emotion + accents + ambience + BGM + SFX
- Multimodal input: text + optional reference audio (voice cloning/style) and image
- Layer-aware output that keeps dialogue, music, and effects more separable for post-production
- Up to 2-minute single-session audio generation with voice continuity
- Native-sounding multi-language support (strong Chinese & English)
- Adjustable parameters: speed, pitch, sample rate, output format, etc.
- Web workspace + shared credit API access for production use
Use Cases
- Short-film & video pre-visualization: quickly draft dialogue, foley, ambience and music beds
- Marketing & social ads: create localized product demos, voiceovers and campaign sound design
- Podcasts & radio dramas: multi-character scenes with consistent voices and atmosphere
- Game & XR prototypes: character lines, ambient loops, UI sounds and cinematic moments
- Educational & e-learning content: scenario-based lessons with immersive spatial audio
- Content creators needing fast, coherent full-scene audio without separate TTS + music + SFX tools

Hey makers! Seed Audio 1.0 is ByteDance Seed’s new multimodal audio model that can generate a complete sound scene — multi-speaker dialogue with emotion & accents, background music, ambience, and SFX — all from a single prompt. I built seedaudio.co because I kept running into the same problem: most AI audio tools only do TTS or only music, and stitching everything together is still a pain. This model changes that, so I wanted to make it easy for creators (especially video, ad, podcast and game people) to actually try it without friction. Would love your honest feedback on the interface, generation quality, and what features you’d want next. Feel free to drop any thoughts or questions!
This is really impressive. The ability to generate dialogue, ambience, music, and SFX together from a single prompt feels like a much more practical approach than having to stitch together several different AI audio tools. The multi-speaker emotion and voice continuity are especially interesting for video and storytelling. Definitely going to give this a try.
