What It Does
Seed Audio 1.0 is a multimodal AI audio generation model designed to create complete sound scenes rather than voice-only narration. It can use text, image, and audio references to generate multi-speaker dialogue, emotional delivery, accents, ambience, background music, and foley-style effects in a single workflow. It is primarily suited to creators working on audio drama, video sound design, dubbing, advertising, games, podcasts, and other projects that need layered audio.
A typical workflow starts with a production-style prompt describing the scene, speakers, language, emotion, ambience, music, sound effects, and timing. Users can optionally provide up to three audio references or one image reference, choose output controls such as format, sample rate, speed, volume, and pitch, then generate, review, download, or revise the resulting audio.

Frequently Asked Questions
Is Seed Audio 1.0 better than traditional text-to-speech?
Seed Audio 1.0 is designed for complete sound scenes, while traditional TTS primarily converts written text into speech. Seed Audio 1.0 is therefore better suited to projects where music, ambience, sound effects, and dialogue need to work together.
How does Seed Audio 1.0 compare with ElevenLabs?
ElevenLabs provides a broader collection of dedicated audio tools, including text-to-speech, voice cloning, music generation, sound effects, dubbing, and an integrated editor. Seed Audio 1.0 is more specifically positioned around generating complete sound scenes from a production-style prompt.
Can Seed Audio 1.0 use reference audio?
Yes. The supplied documentation states that users can provide up to three audio references for voice or style direction. The prompt guide recommends explicitly mapping each reference to the relevant speaker or style.
Can Seed Audio 1.0 generate music and sound effects?
Yes. The documented capabilities include background music, ambience, foley, footsteps, impacts, doors, environmental sounds, and other sound effects alongside dialogue.
Is Seed Audio 1.0 suitable for long audio projects?
It can support longer sound scenes, but each generation is limited to approximately 2 minutes. Projects requiring substantially longer continuous outputs would need additional generation and editing workflows.
