12 free boom sound effects
When to use a boom sound effect
- On the one sentence that matters most: the claim, the result, the twist.
- On a title card or the first frame of a hook.
- After a riser, on the reveal.
- Once per video: a boom on every line loses its punch.

How to add these sounds to TikTok, Reels, Shorts and CapCut
TikTok
The TikTok editor adds sounds from its own library. To use a downloaded sound, mix it into your video in an editor first (CapCut, StoryCut or any desktop editor), then upload the finished video.
Instagram Reels
The Reels editor uses Instagram’s library. Meta’s Edits app can import audio files from your phone, or mix the sound in an editor before you upload.
YouTube Shorts
The Shorts editor adds one track and a voiceover. For sound effects at exact moments, place them in an editor and upload the finished Short.
CapCut
Import the MP3 (desktop: drag it into the media panel; mobile: tap Audio, then Sounds, and import it from your device), drag it to the cut or the word, and keep it quieter than your voice.
Timing and volume matter more than the sound: start it on the first syllable of the word, peak whooshes on the cut, and keep effects 6 to 12 dB under your voice. More in our guide to adding sound effects.
Free for commercial use, no credit needed (CC0)
Every sound in this library is published on Freesound.org under CC0 1.0, the Creative Commons public-domain dedication. You can copy, edit and use it in personal and commercial videos, ads and client work, on any platform, without asking permission or giving credit.
How we picked them: we searched Freesound for CC0 sounds only, kept short, clean, well-rated ones, left out recordings of trademarked sounds (phone, app and game sounds), trimmed the silence, matched the loudness and converted them to MP3. The original sound and its creator are linked under each one.
