Free AI sound effects generator: describe a sound, download the MP3
AIKIZI makes sound effects from a sentence with ElevenLabs' sound-effects model, free for every signed-in account: 20 free minutes a day (40 on Starter, Basic and Pro). Free audio can end at any time. Each effect runs up to 30 seconds, with an optional seamless loop. Sign in with Google, no card; the minutes reset at midnight UTC and are shared with voice and music.
Make a free sound effect · sign in with Google. A five-second example opens in Sound; edit it and press FREE.
What you get
Sound from a sentence
Say what makes it, where, and how it moves: "a stack of plates sliding off a tray onto a tile floor". Foley, impacts, UI blips, creatures, weather.
Seconds, not sounds
A short hit costs only its own length from the day's minutes, so a library of short effects stretches far.
Beds that never click
The loop switch asks the model for an effect that joins end to start, for ambience under a game level or a video.
Past the free minutes
12 1 credits a sound effect (season price). Studio shows which applies before you press Create. Season price, limited time. Normal prices return when the season ends.
How to make one
Open Sound in Studio and sign in with Google.
Describe the sound in one sentence, up to 450 characters.
Set the length, or write it in the prompt and leave it on Auto. Turn on loop for ambience.
Press FREE, listen, and download the MP3 from your Library.
The limits, plainly
- 30 seconds an effect; 450 characters a description (longer ones are shortened to fit).
- Spoken words come out blurred in a sound effect; use the voice generator for lines.
- About 240 five-second effects a day on a Free account (2 times that on Starter, Basic and Pro), fewer if you also make voice or music: all three share the 20 minutes.
- Unused seconds vanish at midnight UTC, when the day starts again.
- Sign in with Google; no card is asked for. Free effects can stop early on a day when every account together reaches the shared daily ceiling, and start again at midnight UTC.
- Free takes are kept for 30 days. Download what you want to keep.
- The free effects belong to a season, not a plan: they can end at any time, and this page will change when they do.

Questions
01How many free sound effects can I make a day?
On AIKIZI the cap is time, not a count. Every signed-in account gets 20 minutes a day this season (40 on Starter, Basic and Pro), which is about 240 five-second sound effects if you make nothing else. Free audio can end at any time.
02How long can one sound effect be?
Up to 30 seconds. Leave the length on Auto and a length written in the prompt, such as "a 3-second door creak", is used; with none, ten seconds are held until the real length is known.
03Can it make a seamless loop?
Yes. Turn on the loop switch and the effect comes back as a seamless loop, for rain, room tone, engines and other beds.
04Can I use the sound effects in a game or an app I sell?
This season, yes. AIKIZI does not claim the effects you make, and ones made with the free minutes may ship inside a game, an app, an ad or a monetised video of your own, under ElevenLabs' terms and AIKIZI's Terms. When the season ends, new audio goes back to credits and its rights follow the ElevenLabs plan AIKIZI is on then.
05What if my description is very long?
The sound model takes 450 characters. A longer description is shortened to its last whole sentence or word that fits, instead of failing.
