Seed Audio 1.0 FAQs
What is Seed Audio 1.0?
Seed Audio 1.0 is ByteDance’s text-to-audio model for natural speech and directed audio scenes. On MixVio you write a script or scene brief, generate one private 44.1 kHz MP3, and review pronunciation before delivery—credits shown first.

How do I direct timing and speakers?
Describe each speaker’s age, tone, and delivery in the prompt, and use time ranges like [2.8s:8.4s] when turns must land on specific beats. Vague “make it cinematic” lines are weaker than naming who speaks, when, and what the space sounds like.
