Example outputs
Input: "heavy wooden door creaking open slowly in a stone castle hall, deep echo", 3 seconds. Model: ElevenLabs Sound Effects v2, 2 credits.
Input: "sci-fi laser cannon charging up with a rising hum, then firing a powerful blast with a short echo", 3 seconds. Model: ElevenLabs Sound Effects v2, 2 credits.
How it works
Describe the sound you need in plain words. Include the source, the environment and any qualities such as volume, texture and duration.
Pick a length: 3, 8 or 15 seconds. Press Generate. ElevenLabs Sound Effects v2 makes the sound in about 10 seconds.
Play the result on the page and download it as an MP3 (44.1 kHz, 128 kbps).

Generate any sound effect from a text description
The AI Sound Effect Generator turns a plain description into a custom audio file. You describe the source, the environment and the qualities you want, and the AI produces a unique sound that matches the description.
Every generated sound is original. No existing recording is repurposed or modified. This means you avoid the licensing concerns that come with stock sound libraries, and you can describe sounds that simply do not exist in any library: a mechanical cat purring on a spaceship, rain falling upward, a ghost sneezing. If you can describe it clearly, the AI will attempt it.
The generator is powered by ElevenLabs Sound Effects v2, and you get an MP3 at 44.1 kHz.
How to write prompts that work
Sound effect prompts work differently from image prompts. The most useful information to include is:
- The source: what is making the sound? A wooden door, a laser cannon, a crowd of people.
- The environment: where is the sound happening? A stone corridor, open space, a forest.
- Qualities: is it sharp or soft? Does it build, sustain or decay? Is it high-pitched or low-pitched?
- Duration: how long should it last? Describe this if it matters: "a 15-second downpour" or "a quick 2-second click".
Avoid vague prompts like "scary sound". Instead: "a low rumbling drone that builds slowly over 10 seconds with occasional distant thumps". The more specific the description, the more useful the result.
Uses for AI sound effects
Custom sound effects are useful across a wide range of projects:
Indie game development: custom SFX for footsteps, weapons, UI events and ambience without paying per-sound licensing fees. The MP3 imports into Unity and Godot.
YouTube and Twitch: unique sounds for stream alerts, channel intros and video transitions.
Podcast production: intro stingers, scene transition sounds and ambient backgrounds generated to fit the podcast's tone exactly.
Anime and video projects: sound effects for fight impacts, magical spells, environmental ambience and mechanical sounds in AI-generated anime videos.
Presentations and explainer videos: clean UI sounds, notification tones and transition stings for professional-looking presentations.
Comparing AI sound effects to free libraries
Free libraries like Freesound.org and the BBC Sound Effects Archive are large and genuinely useful. They have specific strengths: real field recordings, historical sounds and very precise naturalistic audio. Their limitations are equally specific: the exact sound you need may not exist, licenses vary by file (some are creative commons non-commercial only), and nothing stops another creator from using the same recording.
AI-generated sound effects solve a specific problem: when you need a sound that is precisely what you imagined, with no license restrictions and no hunting through thousands of files. The trade-off is that a real recording of rain may have a more natural texture than a generated one. For many projects, generated sounds are indistinguishable or preferable. For others, a real recording is better.
The practical answer is to use both: free libraries for naturalistic recordings where they exist, AI generation for sounds that are unusual, composite or need to fit an exact description.
Frequently asked questions
How do I make sound effects with AI for free?
Sign up with an email address and you get 40 free trial credits. A 3 second sound costs 2 credits, so that is about 20 sounds. Paid plans start at $12 a month for 1,000 credits. You need a free account to generate.
Are the AI-generated sound effects royalty free?
Every paid plan includes commercial use of what you make here, with no royalties to pay per use: videos, streams, games, podcasts and client work.
Can I use them in my YouTube videos?
Yes. Each sound is generated new from your description, not taken from a stock library.
Can I use them in games?
Yes. The MP3 imports into Unity, Godot and most other engines. If your engine prefers WAV or OGG, convert the file in any audio tool.
How long can a sound be?
You can pick 3, 8 or 15 seconds. They cost 2, 4 and 8 credits. For longer ambience, make a few sounds and layer or loop them in your editor.
What format does it download in?
MP3 at 44.1 kHz and 128 kbps, stereo. It plays in every video editor and browser.
How is this different from Freesound or the BBC Sound Effects library?
Freesound and BBC Sound Effects have existing recordings, but they may not have the exact sound you need, and some have license restrictions. With AI generation, you describe exactly what you need and get a new sound in seconds.
