| Platform | Editing tip |
|---|---|
| YouTube / TikTok | Keep hits short; verify license for monetization |
| Podcasts | Use beds sparingly (−18 dB) under hosts |
| Games | Normalize peaks; map one-shots to events |
| Ads / client work | Export stems + keep license screenshot |
Pro tip: Sci-fi beeps clutter mixes fast — one signature laser or HUD tone per scene is enough. Pair with YouTube music, gaming music, or browse filters when you need underscore plus SFX.
