• Preserves the natural tone of the speaker's voice, making your content sound more polished and professional without needing advanced audio skills.
• Speeds up the editing process by reducing the need for manual noise removal or layering multiple audio effects.
• Enhances viewer engagement and clarity, especially in content where the spoken message is central like tutorials, podcasts, or explainer videos.

• Step 1.Open DaVinci Resolve and launch your project. Make sure your audio or video clip is placed on the timeline.

• Step 7.If needed, fine-tune the effect using available parameters under the Detection, Smoothing, and Output sections. For example, adjust the Threshold to control how much noise reduction is applied, Sensitivity to determine how responsive the filter is to noise, and Ratio to define how the filter behaves relative to your voice signal.

• Step 8.Under Smoothing, use the Frequency setting to fix any harmonic ringing caused by the filter. In the Output section, balance the Dry/Wet mix and adjust the Level to control how much of the cleaned audio is applied.

  

• Step 9.Play the audio back and make small adjustments until your voice sounds clean and natural without losing quality.

• Step 10.Once satisfied, save your project. Your audio is now processed with DaVinci Resolve's voice isolation using the Noise Reduction effect.

Fix: In order to use voice isolation, you must upgrade to DaVinci Resolve Studio. Once upgraded, go to Fairlight page and the voice isolation option is found in the Audio FX section of the Inspector panel.

2. Voice Sounds Unnatural

Reason: When you increase the isolation level too much, the software may go past the processing of the audio and turn into a sound like a robot or a harsh sound. It is due to the fact that it begins deleting the frequency of the audio as well as background noise.

Fix: Move the Inspector slider down to lower the voice isolation intensity. Monitor the playback and decrease it gradually, finding the perfect balance to clean the audio without eliminating the background noise.

3. Lag or Audio Delay

Reason: Real-time audio effects like voice isolation DaVinci resolve lead to excessive system loads, resulting in rags, audio delays, or pauses in playback, particularly when RAM and CPU are absent.

Fix: To resolve the lag, lower the playback resolution, disable other effects, and close the background app. For smoother results, use Render in Place to process audio before previewing to reduce the load on your system during editing.

4. Noise Still Present

Reason: Speech separation is not perfect. It is effective for stable background sounds, but it may be difficult to cope with large noise mixed with complex noise and audio. Even if the effect is applied, some noise may remain.

Fix: Fairlight merges voice separation with noise reduction or EQ settings to achieve improved results.
