## Core Model Context

- Seed Audio 2.0 is positioned as a multimodal sound-scene model rather than only a text-to-speech system.
- The published specification describes T2A, TA2A, TV2A, and TAV2A inputs, up to six minutes of audio, as many as six audio references, and support for 30 languages.
- Seed Audio 2.0 is described as producing separate dialogue, music, ambience, and sound-effect stems with more precise timestamp control.
- A strong prompt should define characters, setting, emotion, pacing, spoken dialogue, music mood, ambience, specific sound events, and important timing cues.
- These Seed Audio 2.0 capabilities are upcoming on SeedAudio.co; the currently available generator still runs Seed Audio 1.0.
- Commercial use depends on the terms of the access channel used to generate audio. Users should check output rights before publishing.

## Prompt Guidance

- Write a production brief with the input mode, scene type, target duration, location, characters, language, emotion, pacing, references, stem intent, and timing cues.
- Write dialogue or describe the conversation structure when spoken content matters.
- Specify ambience such as room tone, weather, crowds, traffic, machinery, or environmental texture.
- Specify music direction such as tempo, mood, instrumentation, intensity, and where it should enter or fade.
- List foley or sound effects in sequence, including timing and intensity when important.

## High-Value Use Cases

- Film, short drama, and video dubbing: coordinate dialogue, atmosphere, foley, and music against picture.
- Advertising and localization: preserve voices while adapting language, timing, music, and effects for different markets.
- Game and interactive production: create character dialogue, ambience, music, UI sounds, and cinematic moments as editable layers.
- Longer narrative audio: draft multi-character scenes that need more continuity than a short text-to-speech clip.

## Generator Availability And Boundaries

- Seed Audio 2.0 is upcoming and is not currently generating on SeedAudio.co.
- SeedAudio.co currently exposes a Seed Audio 1.0 preview generator for signed-in users when the configured generation provider is available.
- The current homepage generator supports Seed Audio 1.0 prompts, optional preset voice selection, up to three audio references, or one image reference. Audio and image references cannot be combined.
- Free previews are constrained internally and paid generations settle credits from the returned audio duration when available.
- Generated tasks and outputs are tied to the signed-in user account and shown in generation history.
- Exact generation limits, access rules, API terms, and commercial rights depend on the provider channel used to create audio.
- If a user wants to publish generated audio, guide them to review the active service terms, license limits, and output rights first.
