Video Sound Designer
Add procedural music and sound effects to short videos — a light sound designer, not a full DAW.
How to use
- Import an MP4/WebM/MOV you own (stays in your browser).
- Generate music (style, BPM, key, scale) and SFX; place them on the timeline with ducking.
- Preview in sync, then export WAV audio or WebM (picture + mixed audio).
Video Sound Designer
This tool generates simple layered oscillator/noise music and SFX with Web Audio. It is meant for draft Shorts/TikTok sound beds — not studio production. Only upload media you own or have permission to use. Procedural output is not a legal guarantee of copyright-free commercial use.
Export is WAV first, then WebM (video picture re-encoded with mixed audio). MP4 is not offered because it would require ffmpeg.wasm, which this site forbids. Everything runs locally; nothing is uploaded.
Frequently asked questions
Is this AI music?
No. It uses Web Audio oscillators, noise and envelopes with style templates — no AI APIs.
Can I export MP4?
Not in this tool. Use WAV or WebM. Converting WebM→MP4 elsewhere is up to you.
Are my videos uploaded?
No. They stay in memory in your browser until you close the tab.
