Seed Audio 1.0

Seed Audio 1.0 is presented as a multimodal AI audio generation model rather than a plain text-to-speech tool. Users write a sound-scene prompt, optionally add up to three audio references or one image reference, choose output settings, and generate audio in the SeedAudio.co workspace. The page states outputs are fully mixed audio scenes up to about 2 minutes, with free users limited to about 8 seconds per generation. It describes voice cloning from authorized reference clips (about 30 seconds or less), timeline control for dialogue timing, and natural-language control of emotion, tone, accent, and pacing. Pricing includes a free tier with 10 credits, Pro and Max subscription plans, and credit packs, with API access included in paid plans and one shared credit balance across web app and API. Commercial use depends on the terms of the access channel used.
