Synthesize Sound Effects

How ElevenLabs SFX works

Go from a written acoustic description to clean, master-ready audio files in three simple steps.

Describe the Acoustic Event

Detail the physical materials, resonant environment, and sound dynamics using acoustic terminology.

Set Duration and Influence

Specify a target length between 0.5 and 22.0 seconds or let the model calculate natural duration, then adjust prompt influence.

Export Production Audio

Render and download your synthesized sound effect in lossless PCM 44.1kHz, MP3, or Opus formats.

What ElevenLabs SFX is good at

Explore generative acoustic synthesis engineered for precise duration control, natural decay, and clean spectral clarity.

Acoustic Material Resonance

Synthesize physical interactions with natural acoustic decay across wood, stone, glass, and metal, capturing realistic microphone perspective and material weight.

Variable Duration Timing

Lock sound cues to precise timeline markers with adjustable clip lengths from 0.5 to 22.0 seconds, or leave duration unset for automatic acoustic envelope shaping.

Cinematic Risers and Sub Drops

Generate wide stereo trailer whooshes, modular synthesizer risers, and low-end braams engineered with crisp transient attacks and minimal phase smearing.

Studio-Grade Audio Export

Export uncompressed PCM 44.1kHz audio for professional mixing in digital audio workstations, or lightweight 48kHz Opus and 192kbps MP3 formats for web applications.

What people build with ElevenLabs SFX

Discover how game developers, film editors, sound designers, and UI engineers synthesize custom audio assets on demand.

Game Audio and Foley Design

Synthesize bespoke item pickups, footstep variations, weapon clicks, and UI interactions without searching repetitive stock audio libraries.

Film and Video Post-Production

Populate film timelines with bespoke physical foley, cloth movements, door slams, and footsteps tailored to on-screen pacing and shot depth.

Trailers and Commercial Spots

Build dramatic narrative tension with custom sub-bass drops, sweeping transitional whooshes, glitch impacts, and dynamic synth risers.

Environmental Room Tone Beds

Synthesize seamless background environments, acoustic room tones, weather beds, and atmospheric drones up to 22.0 seconds per generation.

Interactive UI and App Audio

Craft distinct brand sounds, button clicks, notification chimes, and alert tones with lossless 44.1kHz PCM fidelity for native app deployment.

Frequently Asked Questions

The model is purpose-built for discrete foley, cinematic impacts, interface cues, transitional whooshes, sci-fi synthesis, and environmental room tone beds. It is not designed for full multi-instrument musical compositions, intelligible human speech, or stem separation.

You can specify exact durations from 0.5 to 22.0 seconds, or omit the parameter entirely to let the model determine the natural duration from your prompt. For brief transients like clicks or impacts, short durations prevent unnatural trailing flutter, while values up to 22.0 seconds suit continuous ambient soundscapes.

Use the prompt influence parameter, which scales from 0.0 to 1.0 with a default of 0.3. Higher values (0.6 to 0.8) enforce stricter adherence to literal acoustic prompts, while lower settings (0.1 to 0.2) encourage creative variation for experimental or abstract sound design.

The model outputs uncompressed PCM audio at 44.1kHz for lossless DAW editing, MP3 streams at 64kbps, 128kbps, or 192kbps at 44.1kHz, and Opus audio at 128kbps at 48kHz for low-latency interactive applications.

ElevenLabs developed and released this specialized text-to-audio foundation model on May 31, 2024. It was trained on extensive licensed audio datasets to generate realistic physical acoustic resonance without relying on pre-recorded stock audio libraries.
