Add detail, transitions, and emphasis with SFX.

Sound effects work best when they clarify an action or create a production beat. Search the library, upload an owned asset, or generate a candidate, then place it precisely on the SFX lane.

Find an effect

Open the SFX selector and use search terms that describe the audible event: source, material, movement, intensity, distance, and environment.

• Soft UI confirmation, short, clean
• Car door close, exterior, realistic
• Cinematic impact, restrained, no tail
• Coastal ambience, distant waves, calm

Preview the result and add useful candidates to Favorites when available.

Generate with AI

1. Open AI Generate in the SFX selector.
2. Describe one clear audible event: its source, material, movement, intensity, distance, and environment.
3. Choose Duration:
   • Auto lets the generator choose a suitable length.
   • Fixed requests a target from 0.5 to 30 seconds.
4. Enable Loop when the result should repeat seamlessly.
5. If needed, open Advanced and adjust Prompt adherence. Lower values allow more creative freedom; higher values follow the prompt more strictly. The default is 30.
6. Click Generate, preview the returned candidate, and confirm it when it fits the creative.

The requested fixed duration is a generation target. Review the actual duration shown on the result card. For looped effects, also audition the transition from the end back to the beginning.

Upload an effect

Upload is a staged flow: choose the file, preview it, then confirm or discard. Confirm only assets your account is authorized to use and distribute.

Place it on the timeline

• Drag the clip to the intended production beat.
• Resize within the available source duration.
• Layer multiple effects only when each has a clear role.
• Use the playhead and waveform to align transients.
• Check the event under the voice and music, not solo only.

If a resize stops at the edge, the source has reached its available limit. Drag the opposite edge or choose a longer source rather than expecting synthetic audio beyond the file.

Mix SFX

Use the SFX lane preset for a consistent starting point, then adjust a specific clip only when it needs separate treatment. Clip effects are applied before lane effects in the final production chain.

• Lower gain before adding heavy compression.
• Use fades to remove abrupt ambience edges.
• Keep important speech intelligible during impacts.
• Check on speakers as well as headphones.

Common roles

SFX approval checklist

• The effect has an editorial purpose.
• Its transient does not obscure a key word.
• The source and commercial rights are known.
• The duration and ending are intentional.
• Layered effects do not create unexpected peaks.
