How do I make a sound effect with AI?

Describe the sound in one sentence, pick a length and click Generate sound effect. The MP3 appears on the page a few seconds later, ready to play and download.

Which model makes the sounds?

ElevenLabs Sound Effects v2, which Cicadas runs through fal.ai. We are not affiliated with ElevenLabs, and the official ElevenLabs app has its own plans and features.

How much does a sound effect cost?

Half a credit per second, rounded up: 1 or 2 seconds cost 1 credit, 5 seconds 3 credits, 22 seconds 11 credits. You are charged once when you click; if the sound fails, the credits come back.

How good are the sounds, and how fast?

In our test on 2026-10-01, four effects of 2 to 10 seconds were ready 6 to 14 seconds after we clicked, each exactly the length asked for. An automated listener that was not shown the prompts described them as glass shattering, steady rain, a mechanical whoosh with a hum and a clank, and a synthesized whoosh. Listen before you use a sound: it may not match every detail you wrote.

Can I use the sound effects in my videos?

Yes, they are yours to download and add to your edits. Do not describe a copyrighted recording or a real person's voice; the content policy applies to sound too.

Can it add sound to a video I already have?

Not on this page yet. Generate the effect here and add it in your editor, or make a new clip with sound on the AI video with sound page.
