Sound effects from a sentence
How to describe a sound so ElevenLabs makes the one your scene needs: source, space, motion; seconds and loops; a night-street scene in six takes. Free in AIKIZI Studio, 10 minutes a day.
Describe three things: the source, the space it is in, and how it moves. "Heavy wooden door closing in a stone hallway, one slow swing, a soft latch" gets you the door. "Door sound" gets you a guess. Set the length yourself, and turn on loop for anything that has to run under a scene.
Sound libraries are big and never quite right. The door is too modern, the rain is too heavy, the crowd is the wrong size. A text-to-sound model fixes the exact problem: you describe the sound your scene needs and it makes that one. ElevenLabs' sound-effects model is the one AIKIZI Studio runs, and it is unusually good at reading a sentence as a recording brief.
Source, space, motion
What makes the sound
Material and size. "Thin glass", "heavy iron", "a small dog", "a single bicycle". The material sets the timbre before anything else.
Where it happens
"In a tiled bathroom", "across an open field", "inside a car with the windows up". Space sets the reverb and the distance.
How it moves in time
"One slow swing", "three quick taps", "passing left to right", "fading in over four seconds". Motion sets the shape of the sound.
Leave out the mood
"Scary door" does nothing. "Rusted iron door, slow, with a dry hinge squeal, in an empty basement" is scary because it is specific.
Length and influence
Set the duration yourself. Most hits and one-shots want one to three seconds; leave it longer and the model pads the tail. Ambience wants the full length you will use under the scene. Studio takes one to thirty seconds a take.
There is a second control, prompt influence, that the model reads as "how literally should I take this". Studio leaves it at the model's default, which is the right place for nearly everything. If a result feels generic, the fix is a more specific sentence, not a higher setting.
| You want | Write | Seconds |
|---|---|---|
| A door | Heavy wooden door closing in a stone hallway, one slow swing, soft latch | 3 |
| Rain outside | Steady rain on a tin roof, heard from inside a small room, no thunder | 20, loop |
| A footstep | Single footstep, leather sole on wet concrete, close | 1 |
| A market | Small evening street market, twenty people, distant scooters, no music | 30, loop |
| A UI click | Short soft plastic click, dry, close, no reverb | 1 |
| A whoosh | Fast cloth whoosh passing left to right, close, with a short tail | 2 |
Loops and beds
Anything that runs under a scene, rain, wind, a room tone, a crowd, should loop without a seam. Turn on Loop in Studio and the model returns a take whose end meets its start; you can set it on repeat and forget it. Ask for beds without events: "no thunder", "no voices", "no music". Events belong on their own take, so you can place them.
A good scene is three or four takes stacked, not one sentence that asks for everything. Bed, one or two events, a texture. Each is its own short prompt.
A scene in six sounds
A night street, a character walks to a door, goes in. Six takes, about a minute of the day's ten free minutes:
- Bed, 30 s, loop: quiet city street at night, distant traffic, one far dog, light wind.
- Footsteps, 6 s: slow footsteps, leather soles on wet asphalt, approaching, close.
- Keys, 2 s: a small bunch of keys lifted from a coat pocket, close.
- Lock, 2 s: old brass lock turning, one click, close.
- Door, 3 s: heavy wooden door opening inward with a low creak, then closing, soft latch.
- Room, 20 s, loop: silent apartment, a refrigerator hum, a clock, no traffic.
Doing it in AIKIZI Studio
Open Studio, pick SFX, set the seconds, flip Loop for beds, write the sentence, press Create. Each take plays in the Sonic Field player and lands in your Library with a download. A five-second sound uses five seconds of the free ten minutes, so a whole scene costs nothing.
