What it does

SFX Engine generates sound effects from a text prompt. You describe the sound, including its material, distance, mood or length, generate up to four variations side by side, pick one and download it for a video edit, game, podcast or DAW. The site says it handles ambience, foley, impacts, whooshes, UI sounds, creatures, vehicles, sci-fi and magic effects up to 47 seconds long, usually generated in 5 to 15 seconds. It says the tool is not built for full songs, melodies or vocals. A public library of generated sounds can also be browsed by category such as video game, footsteps, explosions and nature. The site describes every generated sound as royalty-free and licensed for commercial use. It also lists background music creation, DJ transitions and a stem splitter as features, and its plans mention API access.
