Boom Riser

The rising sweep that climbs and lands on a low boom, the whole trailer gesture in one clip. Describe the boom riser your cut needs, from a long cinematic swell to a short snap, and Morphic generates it in seconds.

  • Choose how steeply the build climbs and how much low end arrives when it finally lands
  • A build made for your cut instead of the trailer preset that shipped with everyone's editor
  • Arrives with the impact and its tail intact, so the hit still rings underneath your title card

Boom risers for trailers, video, and games

Classic boom riser

The familiar rising tone that resolves into a low hit, the default when you want an audience braced before a cut.

Modifier le prompt

Cinematic swell

Orchestral in feel, wide and harmonic, with a warmer climb suited to prestige trailers and emotional reveals.

Modifier le prompt

Short snap

A compressed climb and impact packed into a brief span, for fast social cuts where a long build would overstay.

Modifier le prompt

Reverse swell

Runs backwards into the moment, pulling air out of the scene rather than pushing it, useful just before a hard silence.

Modifier le prompt

Sub boom riser

Weighted almost entirely in the bass, felt more than heard, for reveals playing on cinema rigs or good headphones.

Modifier le prompt

Noise boom riser

Built from filtered noise instead of tone, abrasive and modern, at home in sci-fi and hard-edged action work.

Ways to use a boom riser sound effect

Hit the moment your title slams on

Line the swell up so the boom lands on the frame your logo appears and the title feels inevitable. The same timing trick works on podcast intros.

When the gap before a reveal feels empty

Bridge a silent stretch before a reveal so the wait feels deliberate, handy in game cutscenes, event openers and social edits that need momentum.

Dread building under a quiet room

Held low and quiet, a slow riser turns an ordinary room tense long before anything happens, which is why horror shorts and audio dramas lean on it.

Whatever is coming has not arrived yet

A build with no visible source suggests scale: a ship, an army, a storm arriving just outside the frame of your film or your level.

Questions fréquentes

What is a boom riser sound effect?
A boom riser is a two-part cue: a rising sweep that climbs in pitch or intensity, and a low boom that it lands on. It is a complete gesture in one clip, carrying both the anticipation and the payoff, which is why trailer and title sound design uses it to pull an audience into a cut and stamp the arrival at the same time.
Where can I get a boom riser sound for a video?
Generate one rather than search for it. Describing the rise and hit you want takes less time than digging through a stock library, and you get the exact gesture your cut needs instead of the closest available clip. 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 boom riser sound effect?
Describe the rise, how long it climbs, and the hit it lands on, then generate it. A prompt like "an airy whoosh rising in pitch then landing on a low boom" gives Morphic enough to work with, and you can adjust the length of the rise so the boom lands on your cut.
What is the difference between a boom riser and a build up?
A build up is the rise on its own: it climbs and hands off, and you place the hit yourself. A boom riser bakes the landing in, ending on a low boom, so it is a single self-contained gesture. Use a build up when you want to control exactly where the drop lands, and a boom riser when you want the rise and the hit as one clip.
Can I use these boom riser sounds commercially?
Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. Because each sound is generated rather than pulled from a shared library, you also avoid the clip turning up in someone else's video.
Why does my boom riser not sit right in the edit?
Usually it is the length of the rise rather than the sound itself. The boom has to land on the exact frame the picture cuts, so if the sweep is too long or too short the hit arrives early or late. Generate a version whose rise matches the seconds before your cut, and line the boom up to the frame the picture changes.
