ElevenLabs SFX v3: AI Sound Effects Generator

What is ElevenLabs SFX v3?

ElevenLabs SFX v3 is a text-to-sound-effects model that turns a written description into an original, royalty-free sound effect up to 30 seconds long. Describe a single sound - a camera shutter, a creaking door - or a full scene with several sounds happening in sequence, and SFX v3 renders them together as one clip. It is the newest ElevenLabs sound effects model, and its biggest step over SFX v2 is reliability: when a prompt lists multiple sounds, more of them land, in the order you wrote.

Key Features

• •Multi-sound prompts: describe several sounds in one prompt and hear them in sequence - a cheer, a ball drop, a boo - without stitching clips by hand.
• •Stronger music and vocals: short musical phrases, drum loops and vocal textures sound more convincing.
• •Cleaner, natural audio: resonant sounds like gongs, chimes and whistles keep their ring without clipping.
• •Seamless looping: generate ambiences and beds that repeat with no audible start or end.
• •Duration control: 0.5 to 30 seconds, or let the model pick a length that fits the prompt.
• •Flexible output: MP3, Opus or WAV up to 48 kHz, all royalty-free.

Best Use Cases

SFX v3 suits film and trailer sound design, game and interactive audio, Foley for video, UI and notification sounds, and ambient beds for long passages. Because it follows multi-part prompts, you can build a whole scene's sound from one description - start with the main action, add the surroundings, then refine the wording.

Prompt Tips and Output Quality

Describe the action, setting and atmosphere rather than a broad category, and order the events as you want to hear them ("hammer strike, ringing metal, then a steam hiss"). Raise prompt influence for a literal reading and lower it for more variety. Avoid exact repetition counts, which are not always followed. In testing, a layered forge sequence rendered cleanly as an 8-second clip with three distinct, in-order events.

How to Use ElevenLabs SFX v3

ElevenLabs SFX v3 generates sound effects from a text prompt. Write what you want to hear, set a length if you need one, and the model returns an original, royalty-free clip up to 30 seconds.

Writing the prompt

Describe the action, setting and atmosphere, not a broad label - "heavy wooden door creaking open in a stone hall" beats "door sound". For a scene, list each sound in the order it should play: "footsteps on gravel, then a metal gate opens, then wind through trees". SFX v3 is built to follow these multi-part prompts, so more of the sounds you name actually appear. Small wording changes matter, so try a synonym if a sound is off.

Choosing parameters

• •Duration: set duration_seconds (0.5 to 30) when a clip must fit a cut; leave it empty to let the model choose.
• •Loop: enable for ambiences and backgrounds that must repeat seamlessly under long passages.
• •Prompt influence: raise it (0.6 to 1.0) to follow a precise brief literally; lower it (0.1 to 0.3) for more creative variation.
• •Output format: keep MP3 for general use; choose WAV 48 kHz for high-quality, non-looping masters.

Recommended Settings

For a layered, multi-sound effect, the tested default works well: a descriptive, in-order prompt with duration_seconds 8 and prompt_influence 0.5 produced a clean clip with three distinct, sequential events. For ambient beds, raise duration toward 20 to 30 seconds and turn looping on. For single impact sounds, a short duration of 1 to 3 seconds is enough. Avoid asking for an exact number of repetitions - the count is not reliably followed.

Music and vocals

SFX v3 also handles short musical phrases, drum loops and vocal textures. Use it for stings and accents; for full compositions, reach for a dedicated music model.

Examples to try

Each example below ran end to end at the settings shown - a descriptive, in-order prompt at prompt_influence 0.5, with duration_seconds and looping carried over exactly as listed.

• •Multi-sound sequence in one prompt. Prompt: "A blacksmith's hammer strikes hot steel on an anvil, the metal ringing and fading between blows, then the glowing blade plunges into a water trough with a sharp hiss of steam". Three named events land in order in one 8-second clip. Tip: list each sound in the order it should play.
• •Music and vocals together. Prompt: "A street busker fingerpicks a phrase on a steel-string guitar while a woman sings a short wordless melody over it; footsteps and murmurs echo through a subway station". A pitched guitar phrase and a sung melody sit over station ambience without garbling. Tip: name the instrument, the voice and the surroundings.
• •A whistle that holds its tone. Prompt: "A stovetop kettle heats on the burner, its rising hiss building into a steady high whistle, then a hand lifts it clear and the whistle falls away". The high whistle holds a steady, clean tone, then falls as it is lifted - no harsh clipping. Tip: describe the arc: rise, hold, release.
• •Seamless looping bed. Prompt: "A tropical coral reef underwater - steady water movement, the constant crackle of snapping shrimp, and a distant whale call rolling past". A 30-second ambience that repeats with no audible seam. Tip: turn loop on and push duration_seconds to 20-30 for beds.

More to try: "Footsteps on gravel, then a metal gate opens, then wind through trees", "Vintage brass stabs in F minor", "Heavy rain on a tin roof, thunder rolling in the distance".
