How to Remove Background Noise in DaVinci Resolve
By the Inverse.AI team · Updated June 2026
Quick answer: In DaVinci Resolve, go to the Fairlight page, select your audio clip, and in the clip inspector enable Voice Isolation — Resolve's AI dialogue cleaner — then adjust the Amount dial. For finer control use the Dialogue Processor (Studio) or the Noise Reduction panel. Voice Isolation is the single best one-control fix. When it over-processes (thin, watery voice) or you're on the free version and want a stronger result, clean the exported file with a dedicated tool like Noise Reducer.
DaVinci Resolve has some of the best built-in audio cleanup of any editor — but the controls live in Fairlight, and the strongest options are split between the free and Studio versions. Here's the fastest path to clean dialogue, what you get for free vs paid, and when to reach for a specialist tool.
The one-control fix: Voice Isolation (Fairlight)
- Switch to the Fairlight page (bottom toolbar).
- Select the dialogue clip.
- In the Inspector, find Voice Isolation and toggle it on.
- Adjust the Amount — start around 40–50% and raise only as needed. Voice Isolation uses a neural model to lift speech out of noise, and it's remarkably good on traffic, wind and room tone.
This single control replaces most manual de-noising for talking-head and interview footage.
Finer control: the Dialogue / Noise Reduction tools
- Noise Reduction panel (in the clip's effects / Fairlight FX): supports a Learn mode — sample a noise-only section so Resolve knows the noise profile, then dial the Threshold/Attenuation.
- Dereverb and Dialogue Processor give targeted echo and tonal control (Dialogue Processor is a Studio feature).
Free vs Studio — what you actually get
- Voice Isolation: available in current Resolve versions including the free edition (it moved out of Studio-only in recent releases — verify on your version).
- Dialogue Processor, some advanced Fairlight FX, and higher render options: Studio only.
- If you're on the free version and Voice Isolation isn't enough, you don't have the full Studio dialogue chain to fall back on — which is exactly when an online cleaner earns its place.
Best order of operations
- Voice Isolation (or Noise Reduction with a learned profile) first.
- Dereverb for room echo.
- EQ to restore warmth/clarity.
- Compression/limiting last for consistent level.
Avoid stacking Voice Isolation at 100% with heavy Noise Reduction — you'll get a watery, artifact-laden voice.
When to clean the exported file online instead
If Voice Isolation over-processes the voice, you're on the free edition, or you simply want a fast one-step result, export and run the file through a model built specifically for noise removal. Noise Reducer uses a custom Mel-band neural network with a LoRA adaptation layer to separate voice from noise — wind, traffic, hum, hiss, chatter — while keeping speech natural. It accepts your video directly (MP4, MOV, MKV) and returns it cleaned in about 30 seconds: clean a video here or enhance muffled speech here.
Frequently asked questions
Where is Voice Isolation in DaVinci Resolve?
On the Fairlight page: select the clip, open the Inspector, and toggle Voice Isolation, then set the Amount.
Is Voice Isolation free in DaVinci Resolve?
It's available in the free edition of current versions (verify on yours); the Dialogue Processor and some advanced Fairlight FX remain Studio-only.
Why does Voice Isolation make my audio sound watery?
The Amount is too high, or it's stacked with heavy Noise Reduction. Lower it, remove reverb separately, and if it still sounds off, clean the exported file with Noise Reducer.
Can I remove background noise from a video without using Fairlight?
Yes — upload the whole video to Noise Reducer; it cleans the audio track and returns the video, no Fairlight needed.
