Authentic ambiences and subtle sound design, automatically
Documentary sound that stays true to the story
Documentary sound design is a balancing act — you need to fill gaps in location audio and create atmosphere without making anything feel manufactured. Effct understands this. The Documentary and Natural presets are built specifically for non-fiction work, prioritizing authentic environmental sounds over dramatic effects. Interview scenes get subtle room tone. B-roll gets matched ambiences. Transitions stay clean. The AI respects the reality of your footage while giving it the sonic depth that keeps audiences immersed.

Frequently asked questions
Will the AI add over-the-top sound effects to my documentary?
No. The Documentary and Natural presets are specifically designed for non-fiction. They focus on subtle environmental sounds, room tone, and natural ambiences — never dramatic foley or cinematic whooshes.
Can I keep my existing interview audio and just add ambiences?
Yes. Enable 'Include existing audio' during project setup to preserve your location audio. Effct will layer appropriate ambiences and environmental sounds on top without replacing your original audio.
How does it handle different locations in the same project?
Effct analyzes each scene individually. When your documentary cuts from an indoor interview to outdoor b-roll, the AI detects the change and adjusts the ambience accordingly.
