Seed Audio 1.0

Seed Audio 1.0 is ByteDance Seed's multimodal audio generation model, hosted here as a web workspace: from text, image or audio prompts it produces multi-character dialogue with emotional delivery and authentic accents, ambient soundscapes, background music and realistic foley — complete sound scenes from a single prompt. It's designed for longer-form audio and supports layered output (dialogue, music and effects as separate layers), targeting film, ads, podcasts, games, education and XR prototyping. Free credits with daily check-ins; limited-time launch discount up to 50% off.

Layered output is the feature that matters for actual production — getting dialogue, music and effects as separate stems is the difference between a demo and something you can mix.

Who it's for: podcasters, ad creators and game developers who need full sound scenes rather than isolated TTS lines. As with any model-specific site, judge it on whether Seed Audio's quality fits your content — ByteDance's audio models have been strong in multilingual and expressive delivery, and trying it is free.
