The AI audio generator for dialogue, music & sound effects
Not a TTS that reads text aloud. SeedAudio is an AI audio generator built on ByteDance's Seed-Audio 1.0 — describe one scene and get multi-character dialogue, background music, and sound effects, mixed in a single pass.
Reference voice / image (voice clone · audio-image exclusive)
Only upload or use voices you have the right to use. You are responsible for the audio you generate.

What is Seed-Audio 1.0?
Seed-Audio 1.0 (Chinese name: 豆包音频生成模型) is ByteDance's text-to-audio generation model. From one natural-language prompt it produces a finished audio scene — multi-character dialogue, background music, and sound effects mixed in a single pass — rather than a single text-to-speech voice. SeedAudio is a hosted interface to the model: billed by output duration, with a free first generation and no sign-up required.
One prompt, a full scene
Dialogue, music, and sound effects are generated together and mixed on output, with no separate scoring or editing.
Multiple characters, one pass
Several voices stay distinct and consistent in one clip, with the pauses and emotion of a real conversation.
Billed by output duration
You pay for the audio you actually get, and failed generations are refunded in full.
Three steps to a full scene
No studio, no voice actors, no multitrack post — one description is enough.
Write the script
Choreograph a whole scene in one prompt: characters, lines, emotion, SFX and music. Use the insert bar (+Character · +SFX · +Music · +Emotion), or start from an official template.
Add references (optional)
Upload reference audio to clone a voice (up to 3), or define a character from a single image, keeping the voice consistent across scenes.
Generate in one pass
Multi-character dialogue, background music and sound effects mixed in a single pass. A 2-minute clip renders in about a minute; failed jobs are auto-refunded and output is commercial-ready.
Official templates, one-click remix
Every clip below is a real generation. Listen, then take the template into the studio.

Music & SFX in one pass
Background music, ambience and foley are generated together with the voices. No multitrack editing — output is the final cut.

Upload reference audio to lock a voice across scenes, or define a character from a single image.
