What is Seed Audio 1.0?
Seed Audio 1.0 is an online AI audio generator built around ByteDance Seed's multimodal audio model. Instead of producing a single speech track, it creates full sound scenes, combining multi-speaker dialogue, expressive voices, ambience, background music and foley-style sound effects from one text prompt, with optional image or audio references to guide the result.
Users describe speakers, emotion, language, location, timing, music direction and sound events together, and the model returns one mixed audio track of up to about two minutes per generation. This scene-level approach sets it apart from traditional text to speech, which usually outputs voice only and leaves music, effects and mixing to separate tools. The site also offers API access that shares one credit balance with the web workspace.
