What is SFX Engine?
SFX Engine turns a written description into sound effects for games, video, podcasts and apps, generating up to four takes per prompt. Everything it produces is royalty-free for commercial use, and a library of previously generated sounds can be searched and downloaded.
You describe the sound, adding details like material, distance, mood or length, compare up to four variations and download the one that fits your edit or DAW. Effects can run up to 47 seconds. The same credits also cover background music, DJ transitions, stem splitting and voiceover generation.
An API is included on paid plans for developers who want to generate sounds inside their own apps or games. New users can try five sounds without a card, but downloading requires a subscription, and each take costs three credits.
