SeedAudio
What it is
SeedAudio is a hosted web interface for ByteDance’s Seed-Audio 1.0 text-to-audio model. A natural-language prompt can combine multi-character dialogue, background music, and sound effects in one generation. Users may upload up to three reference audio clips for voice cloning or use one image to define a character; audio and image references cannot be mixed. Studio controls adjust speed, volume, and pitch, with MP3, WAV, and OGG listed as output formats. The script editor allows 3,000 characters, and each generation can run up to about two minutes. Longer pieces are intended to be made in parts. Usage is billed by output duration, and failed generations receive full refunds. The free plan includes 20 sign-up credits and generations up to 60 seconds. Paid plans start at $19.90 a month and allow commercial use. Listed use cases include drama, audiobooks, podcasts, advertising, and game audio.
