How the sound effects generator works
1. Pick your sounds
Enable scream, wind, heartbeat, thunder or any of the 12 original synth patches. Solo a sound to focus on one layer.
2. Tune the mix
Set master volume, track length, intensity and pitch. Every sound reacts to intensity and pitch so you can make it subtle or over-the-top.
3. Export WAV or MP3
Rendered locally at 44.1 kHz 16-bit. Free exports carry a short periodic SpookyMedia chime; Pro removes the watermark.
Frequently asked questions
Are these sound effects original? Can I use them commercially?
Yes. Every effect is synthesized from oscillators and filtered noise inside your own browser — no sampled recordings, no stock libraries. You own the result and can use it in monetized TikTok, Reels, YouTube and Twitch videos with no attribution.
Why synthesize sound effects in the browser instead of downloading MP3s?
Three reasons: privacy (audio never leaves your device), instant customization (intensity, pitch and length are live sliders), and unlimited free use. You also get a custom mix layered exactly the way you want, instead of a one-size stock clip.
What is the audio watermark and how do I remove it?
Free exports insert a short three-note “SpookyMedia” chime roughly every 3 seconds. It is quiet, melodic and easy to duck under dialogue or remove in your editor. Pro removes it entirely along with unlocking batch export and HD mastering.
Which browsers are supported?
Chrome, Edge and Firefox work best for both preview and WAV/MP3 export. Safari supports WebAudio preview and WAV export; MP3 encoding uses the local lamejs encoder and works in all modern browsers. No uploads — everything renders on your machine.
WAV or MP3 — which should I download?
WAV is uncompressed 44.1 kHz 16-bit, best for importing into CapCut, Premiere or DaVinci for further editing. MP3 (128 kbps) is smaller and ready to drop straight into TikTok, Reels, Twitch or a presentation.
