Air raid siren sounds for games, animation, and video edits
Rise and fall wail
The classic civil-defence siren, swelling up and sinking back over and over, for a raid, a disaster or a war film.
Siren wind-up
A siren motor spinning up from silence to a full scream, for the first second of an alert or the start of a lockdown.
Steady alert tone
One held, unbroken siren pitch, for a drill, a test or a warning that will not stop until the danger has passed.
All-clear wind-down
The pitch sinking slowly as the rotor coasts to a stop, for relief after a raid, a drill ending or an eerie aftermath.
Hand-crank siren
A hand-cranked siren whining up and down unevenly, for a small village alarm, a warning at a camp or a factory drill.
Two sirens at once
Two wails out of step, beating against each other, for a whole town being warned at once or a spreading emergency.

Ways to use an air raid siren sound effect
Hold an empty street without a score
A steady alert tone carries a long shot of an abandoned road with no music needed, in a drama, a disaster game or a documentary.
Edit prompt
Tell the audience it is wartime
The rising and falling wail over the opening shot sets the era and the threat before a single plane appears, in film, games and audio drama.
Edit prompt
Let the danger pass off screen
An all-clear wind-down heard from a shelter tells everyone the raid is over without showing the sky, in a period drama, a game or a radio play.

FAQs
What is an air raid siren sound effect?
An air raid siren sound effect is the wail of a large civil-defence siren, made by a motor spinning a slotted rotor that chops air into a scream. Its rising and falling pitch is the sound most people link with wartime warnings.
Where can I get air raid siren sounds for a video?
Generate them from a short prompt on Morphic. Describing the wail you want is quicker than searching a stock library, and every sound on this page was made from the prompt printed beside it, so you can start from one and adjust it.
How do I make a custom air raid siren sound effect?
Describe the siren type, what the pitch is doing and how long it runs, then generate it. A prompt like "a large motor-driven air raid siren, the wail rising slowly to a high scream and falling back again" gives Morphic enough to work with.
What is the difference between a wail, a steady alert and an all clear?
A wail rises and falls over and over and usually means take cover now. A steady alert holds one tone without changing pitch. The all clear says the danger has passed, and depending on the country it is a long steady tone or a slow wind-down.
Can I use these air raid siren sounds commercially?
Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. Because each sound is generated for you, you also avoid the clip turning up in someone else's video.
Why does my air raid siren sound not sit right in the edit?
Usually the siren sounds too close and dry for a huge outdoor horn. Add a long reverb and roll off some top end so it seems to carry over rooftops, and keep it below dialogue. A siren heard indoors should be duller still.
