SFX Engine

SFX Engine turns a text description into a new sound effect that can be downloaded and used in games, films, videos, podcasts, apps, ads and social media. Users describe the sound, optionally adding material, distance, mood or length, generate up to four takes, and download their pick. The page states every generated sound is royalty-free and licensed for commercial use. A free library of sound effects is also available to browse and download. Free trial gives 5 sounds with no card needed; paid plans include commercial use and are priced in credits. Sounds can be up to 47 seconds long, and the tool is not built for full songs, melodies or vocals. Generation typically takes 5 to 15 seconds.
