What is it
Seed Audio 1.0 is ByteDance's universal audio generation model released in June 2026. Unlike traditional text-to-speech systems that simply read words aloud, Seed Audio understands the full spectrum of sound. It generates multi-character dialogue with distinct voices and emotions, background music, realistic sound effects, and immersive ambient soundscapes in a single generation pass. The model accepts both text prompts and reference audio as multimodal input, allowing users to describe a scene or provide a sample for style matching.
Key Features
- One-model generation: Produces voices, music, sound effects, and ambient sounds simultaneously.
- Multimodal input: Accepts text prompts and reference audio clips.
- Up to 2 minutes of continuous audio per generation, extendable with consistent voice characteristics.
- Broadcast-quality output with natural emotion, spatial audio, and no artifacts.
- Multilingual support with natural accents and pronunciation.
- Enterprise integration via Volcano Engine's API and consumer access through ByteDance products like CapCut.
Who Is It For
Seed Audio is designed for content creators, game developers, filmmakers, advertisers, and anyone needing professional audio without a studio. It benefits podcasters, audiobook creators, video producers, e-learning teams, and social media creators who need quick, high-quality audio production.
