Does my original video audio stay?

Yes. Source audio is kept at full volume. SFX are summed on top.

Can I preview sounds before assigning them?

Yes. The play button next to each sound in the picker plays it through your speakers without touching the marker.

Is there a marker limit?

Three on the free plan, unlimited with Pro.

What do the LUFS numbers mean?

Integrated LUFS is the loudness your mix averages out to. YouTube and Spotify normalize to roughly −14, Apple Music to −16, broadcast to −23. True Peak should stay at or under −1 dBTP to survive lossy codecs.

Sound design editor

Sound Design Editor is a browser-based tool that adds sound effects to video. It places markers automatically on beats, flashes and cuts, renders the clip's audio as a waveform you can drag markers on, accepts custom audio uploads, and checks the final mix against broadcast loudness targets (ITU-R BS.1770-4 / EBU R128). Bundled pack covers shutters, whooshes, impacts, risers, sub drops and UI clicks.

Tips

Add a Shutter click on every cut, instant rhythm.
Pair a Sub drop with a black cut marker in Deep Shell for a bigger hit.
The Master slider pulls the whole SFX bed down under dialogue.
If integrated loudness is above −14 LUFS, streaming platforms will turn it down, bring it in range before export.
