What SeedAudio is
SeedAudio is a hosted web interface to ByteDance’s Seed-Audio 1.0 text-to-audio model. A natural-language prompt can generate multi-character dialogue, background music, and sound effects together. Users can upload up to three reference audio clips to clone a voice, or use one image to define a character; audio and image references cannot be combined. The studio provides speed, volume, and pitch controls, with MP3, WAV, and OGG output formats. Its script editor has a 3,000-character limit, and a generation can run for up to about two minutes; the service recommends making longer pieces in parts. Usage is billed by output duration, and failed generations are refunded in full. The Free plan costs nothing and includes 20 sign-up credits, approximately one generation, with up to 60 seconds per generation. Paid plans offer commercial use of generated audio. The listed uses include drama, audiobooks, live commerce, podcasts, short-video ads, and game audio. The Starter plan includes email support, while Studio includes dedicated support.
