To make a whoosh sound effect, reverse a sound with a long, smooth decay — a crash cymbal, a breath, a noise burst with reverb — so its fade-out becomes a swell. Trim the reversed clip to about half a second to a second and a half, fade the front in, and place it so its loudest instant lands exactly on the cut. A free browser tool or a phone handles the reversing; your editor handles the timing.
What makes a sound read as a whoosh?
A whoosh is a short burst of broadband noise whose loudness and brightness rise and then stop — or rise and fall — over a second or so. The ear interprets that shape as motion: something passing close by, air being displaced, a camera swinging to a new shot. It carries no pitch the listener needs to follow and no rhythm, which is why it can sit under dialogue or music without clashing.
Two properties do most of the work. The first is the envelope: energy has to build rather than start at full level. The second is the spectrum: noise-like sources with lots of high-frequency content (air, cymbals, hiss) sound like movement, while tonal sources sound like notes. That is why reversal is such an efficient recipe. Almost every natural sound with a sharp attack and a long tail — a crash, a clap in a big room, a struck sheet of metal — has the wrong envelope forwards and exactly the right one backwards.
A whoosh is a close cousin of the riser. The difference is duration and job: a riser builds anticipation over bars of music, while a whoosh marks one instant of motion and is gone.
Which sources make the best whoosh?
Anything noisy with a smooth tail. Cymbals and breath are the easiest; noise with reverb is the most controllable.
| Source | How to get it | Character after reversing | Best for |
|---|---|---|---|
| Crash or ride cymbal | Record one hit, let it ring | Bright, shimmering, metallic | Music video cuts, energetic edits |
| Breath (“fffff” / “shhhh”) | Blow past the mic, not into it | Soft, airy, human | Vlogs, podcasts, subtle transitions |
| Paper or fabric swipe | Swish a sheet or a jacket past the mic | Textured, dry, close | Swipe-style UI and slide transitions |
| White noise plus reverb | Short noise burst into a long reverb | Smooth, wide, easy to tune | Trailers, title cards, cinematic cuts |
| Reverb tail of any hit | Clap or knock in a large room, record the tail | Roomy, natural | Scene changes that need space |
The cymbal version is covered step by step in how to make a reverse cymbal swell; for a whoosh you just trim it much shorter. If the source has a clear pitch — a piano chord, a sung note — it will still reverse into a swell, but it reads as a musical riser rather than air moving.
How do you make a whoosh on your phone or in the browser?
The quickest route needs no editor at all until the timing step.
- Record or import the source. Blow a long breath past the microphone, strike a pot lid, or import a noise-with-reverb sample. Let the tail decay completely before stopping — the tail is the whoosh.
- Reverse it. In the free audio reverser, drop the file on the page or record straight from the microphone. It flips in the browser with nothing uploaded, lets you A/B the original against the reversed clip, and downloads the result as a WAV.
- Trim it short. Keep only the smooth part of the swell, typically 0.5 to 1.5 seconds, ending at the loudest instant.
- Fade the front in. A short fade from silence hides where the trim begins.
- Export as WAV and import it into your video editor or DAW.
On a phone, Reverse Audio PRO records, reverses, and exports the same way, and adds speed and pitch controls: slowing a reversed breath stretches it into a longer, darker whoosh, and speeding it up tightens it into a quick flick. Platform-specific walkthroughs are in reverse audio on iPhone and on Android.
Where should the whoosh sit relative to the cut?
The loudest point of the whoosh should land on the edit — the first frame of the new shot or the moment a title appears. That peak is where the old attack used to be, and the ear hears it as arrival. If it lands late, the whoosh trails behind the picture and feels like an afterthought; if it lands early, the cut arrives after the energy has already dropped.
Work backwards from the cut. Put the playhead on the first frame of the incoming shot, align the end of the reversed clip there, and let the swell occupy the frames before it. At 24 frames per second each frame is about 42 milliseconds, so nudging the clip by one or two frames is usually all the fine-tuning needed. At 30 fps, a frame is about 33 milliseconds.
Two common variations help:
- Reverse into forward. Follow the reversed swell with a short piece of the original, forward sound. The swell builds into the cut, the forward tail decays away after it, and the pair reads as something rushing past rather than stopping dead.
- Duck the music. Pull the music bed down a few decibels under the whoosh so the transition cuts through without making the overall mix louder.
How do you make a whoosh feel like it is moving?
Add change over the length of the clip, because static noise sounds like hiss while changing noise sounds like motion.
Pan it. Automate the pan from one side to the other across the whoosh, matching the direction the picture moves. A whip-pan to the right wants a whoosh that travels left to right.
Sweep a filter. Automate a low-pass filter opening upward as the whoosh builds. Rising brightness reinforces rising loudness, and the combination reads as approaching.
Shift the pitch. A slight upward pitch glide into the peak and a downward one after it imitates the Doppler effect — the drop in pitch you hear when a car passes. Even a few semitones is enough to suggest it.
Layer, sparingly. A breath layered under a cymbal gives body and shimmer at once. Keep it to two or three layers; more tends to blur into general noise. If you want the same inhale-into-the-hit feel on a voice, reverse reverb is the vocal version of this technique.
