SeedAudio is a web studio for turning text prompts into audio with ByteDance’s Seed-Audio 1.0 model. One natural-language prompt can combine dialogue between characters, background music, and sound effects. To shape a character’s voice, users can provide up to three reference audio clips or one image; the two reference types cannot be combined. The studio includes speed, volume, and pitch controls, with MP3, WAV, and OGG listed as output formats. Its script editor has a 3,000-character limit, and a generation can run for up to about two minutes; longer pieces are recommended in parts. Usage is billed by output duration, and failed generations are refunded in full. The free plan includes 20 sign-up credits, approximately one generation, and generation lengths up to 60 seconds. Paid plans start at $19.90/mo, and audio generated on paid plans can be used commercially. Listed uses include drama, audiobooks, podcasts, live commerce, short-video ads, and game audio.
