What is Audiobox?
Audiobox is an AI audio generation model developed by Meta Research. It lets you create realistic speech in custom voices, generate ambient sound effects, and combine both into rich audio scenes — all from text descriptions or short voice samples. As an open research project, Audiobox is free to experiment with and represents Meta's push toward controllable, versatile audio AI.
