An AI SFX generator: type what you want to hear, from a creaking door to a rainforest morning, and generate it as audio. Set the tempo and key, or make a seamless loop for backgrounds.
Write what happens, what makes the sound and where it is, in up to 500 characters. "Heavy wooden castle door creaking open, then slamming shut with a long stone-hall echo" gives far more to work with than "door".
Leave tempo on Auto for effects, or set 60 to 300 BPM for rhythmic sounds. Choose a key when the sound has to fit a track, and turn on Seamless Loop for ambiences and background beds.
Select Generate Sound. Each sound costs 1 credit with Suno Sounds V6 or V5. Listen, adjust the description and regenerate until it fits.

|---|---|
| Foley | Footsteps on fresh snow, slow and heavy, crunching under winter boots |
| Interface | Soft, friendly notification chime, two rising notes, clean and short |
| Ambience | Busy café at noon, quiet chatter, cups clinking, espresso machine hiss |
| Impact | Deep cinematic boom with a metallic tail, for a trailer title hit |
| Nature | Light rain on a tent with distant thunder rolling in |
| Sci-fi | Spaceship engine powering up, low hum rising into a bright whine |
