Land a title card on the frame
The impact hit has a fast attack and a short decay, so it strikes exactly where you place it and clears before the next beat.

Boom variations for trailers, edits, and games
Cinematic boom
0:06A soft swell opening into a heavy body. The slow attack is what separates a trailer boom from an impact: it arrives rather than hits.
Impact hit
0:03Fast, percussive, and tight. It lands on a frame instead of arriving at one, so it suits a cut where timing has to be exact.
Braam
0:05Detuned brass swelling into a dissonant blast. The detuning is the whole character, and a clean chord does not read as one at all.
Distant boom
0:06Soft and rounded with no front edge at all. Barely an event, which makes it usable under a scene that has to keep running.
Riser into boom
0:08A rising tension build that resolves into the hit. The build is what makes the boom feel earned rather than dropped in.
Boom with debris
0:06The hit followed by small material settling. The debris is what places it somewhere real rather than in a mix.

Ways to use a boom sound effect
Let a long decay carry a held shot
A slow-swelling cinematic boom fills five seconds on its own. It works over a game cinematic as readily as a trailer.
Edit prompt
Build tension and then release it
A riser resolving into a hit gives an audience the anticipation as well as the payoff, which the boom alone never delivers.
Edit prompt
Put a catastrophe over the horizon
A distant boom with no attack tells the audience something enormous happened somewhere else, for the cost of one clip.

FAQs
What is the difference between a cinematic boom and an impact hit?
The attack. A cinematic boom swells in slowly and feels like it arrives, while an impact hit has a fast percussive front and lands on a specific frame. Use the first to fill a held shot and the second to mark a cut.
What is a braam?
A low brass blast built from several detuned notes swelling together into a dissonant sustained chord. The detuning is what gives it the unease; a clean brass chord at the same pitch sounds triumphant rather than ominous.
Why can I not hear my boom on a phone?
Because small speakers cannot reproduce the lowest frequencies. Ask for some grit or distortion in the hit, which adds harmonics higher up that a phone can actually play, or pair the boom with a mid-range element.
How do I make a boom feel earned?
Put a riser in front of it. A build that climbs for a few seconds and resolves into the hit gives an audience anticipation, and the same boom lands considerably harder after one than it does dropped in cold.
How do I stop a boom burying my dialogue?
Shorten the decay and place the hit in a gap rather than under a line. A long low tail sits in the same space as a voice for several seconds, which is what actually swallows the line rather than the peak level.
Can I use these boom sounds commercially?
Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. Because each hit is generated rather than pulled from a shared catalogue, you also avoid the boom already under a thousand other trailers.
