Here is the step-by-step workflow for consistent broadcast-level audio across your timeline." tags: ["DaVinci Resolve", "Audio", "Fairlight", "Tutorial", "Audio Normalization"] --- Set perfect audio volume in DaVinci Resolve by selecting your audio clips, right-clicking, choosing Normalize Audio Levels, and setting the Target Level to -14 LUFS with a True Peak of -1dB. This instantly calculates and adjusts the gain of every clip to a consistent professional volume. For more advanced control, use the Dialogue Leveler plugin on the Fairlight page, which applies real-time compression and gain adjustment to maintain consistent levels across multiple speakers. Cutsio provides an alternative pre-processing workflow — upload your audio to Cutsio, let the Silent Slicer remove dead air and normalize levels, then export an XML to DaVinci Resolve for the final mix. ## What is audio normalization and why does it matter for YouTube? Audio normalization is an automated process that mathematically calculates the average loudness of an audio clip and applies a uniform gain adjustment to bring that volume to a specific target level. This ensures every clip in your timeline plays at the same perceived volume, regardless of how it was recorded. This is the most critical step in audio post-production. If you record an interview with three different microphones — a lavalier, a shotgun, and a USB desktop mic — each speaker will inevitably be a different volume. Without normalization, the viewer must constantly adjust their volume knob, which leads to frustration and early video abandonment. Streaming platforms enforce loudness standards for a reason. YouTube targets -14 LUFS (Loudness Units relative to Full Scale), Spotify targets -14 LUFS, Apple Podcasts targets -16 LUFS, and broadcast television requires -23 LUFS. If your video exceeds these targets, the platform applies downward compression, which can distort your audio. If it falls below, your video sounds quieter than everything else on the platform. Normalization to the correct target ensures your audio sounds competitive on any platform. ## How do you normalize audio on the Edit page? The fastest way to achieve consistent volume across multiple clips is the built-in normalization tool on the Edit page timeline. This method processes all selected clips simultaneously and applies individual gain adjustments to each one. 1. **Select the Clips:** On the Edit page, click and drag to highlight all the dialogue audio clips you want to balance. 2. **Open the Normalization Tool:** Right-click any of the highlighted clips and select "Normalize Audio Levels" from the context menu. 3. **Choose the Target Level:** A dialogue box appears where you set the loudness target. For YouTube, podcasts, and general web delivery, select "Target Loudness (LUFS)" and enter "-14 LUFS." For strict broadcast standards, use "-23 LUFS." 4. **Set the True Peak Limit:** Below the target level, set the True Peak to "-1.0 dB." This prevents any sample from exceeding -1dB, ensuring your audio never clips during playback. 5. **Execute the Change:** Click the "Normalize" button. DaVinci Resolve analyzes each clip's loudness and adjusts the volume lines up or down to match your target. This process is non-destructive. Resolve does not modify the original audio files — it adjusts the clip gain (volume line) on the timeline. You can undo or tweak any clip individually after normalization. ## How do you fix dialogue that fluctuates wildly within a single clip? Normalization fixes the overall volume of a clip, but it does not fix a speaker who whispers one sentence and shouts the next. If the audio fluctuates wildly within the same clip, you must compress the dynamic range using the Fairlight page. To fix fluctuating dialogue on the Fairlight page: 1. **Navigate to Fairlight:** Click the musical note icon at the bottom of the DaVinci Resolve interface. 2. **Open the Inspector:** Select your dialogue track (e.g., Audio 1) and open the Inspector panel on the top right. 3. **Enable the Compressor:** Scroll down to the "Dynamics" section and double-click to open the full dynamics window. Enable the "Compressor" by clicking its power button. 4. **Adjust the Settings:** Lower the "Threshold" to around -20dB. This tells the compressor to start reducing gain on any audio that exceeds -20dB. Set the "Ratio" between 3:1 and 4:1 — this determines how aggressively the compressor reduces loud sounds. 5. **Set Attack and Release:** Set the "Attack" to around 10ms and "Release" to around 100ms. Fast attack catches sudden shouts, while moderate release prevents the compression from sounding unnatural. 6. **Adjust Makeup Gain:** Increase the "Makeup Gain" slider to bring the overall volume of the compressed audio back up to your target level. This makes the whispered sections audible without the shouted sections becoming overwhelming. The compressor automatically squashes the loud parts down to a manageable level while the makeup gain raises the quiet parts. The result is a consistent, listenable audio track where every word is clear regardless of the speaker's original volume. ## How do you use the AI Dialogue Leveler plugin? If you own DaVinci Resolve Studio (the paid version), the software offers an incredibly powerful, one-click AI solution that combines normalization and compression into a single plugin. To apply the Dialogue Leveler: 1. **Navigate to Fairlight:** Go to the Fairlight page. 2. **Open the Effects Library:** Click the Effects button to open the library panel. 3. **Find Dialogue Leveler:** Search for "Dialogue Leveler" under the "Resolve FX Audio" category. 4. **Apply to the Track:** Drag the Dialogue Leveler plugin directly onto your dialogue track header (e.g., Audio 1). This applies the effect to every clip on that track simultaneously, saving you from processing individual clips one by one. 5. **Enable the Plugin:** In the Inspector panel under the Effects tab, toggle the plugin on. The Neural Engine automatically analyzes the spoken words, smoothing out volume inconsistencies without requiring manual compressor settings. 6. **Add Voice Isolation:** If the speaker was recorded in a noisy room — air conditioning, traffic, or computer fans — add the "Voice Isolation" plugin directly above the Dialogue Leveler. The AI instantly removes the background hum while preserving the clean voice, then applies the leveler for consistent volume. The Dialogue Leveler is significantly faster than manual compression. It processes the entire track in real-time and requires no threshold, ratio, or attack settings. For most dialogue-based content, it produces professional results with a single click. ## How do you use audio ducking to balance music and dialogue? Audio ducking automatically lowers the volume of background music whenever someone speaks. This prevents the common problem of music drowning out dialogue during quieter sections of a video. To set up ducking in DaVinci Resolve: 1. **Navigate to Fairlight:** Go to the Fairlight page where your timeline is organized into tracks. 2. **Open Dynamics on the Dialogue Track:** Select your dialogue track (e.g., Audio 1). In the Inspector, open the Dynamics panel and enable the Compressor. Go to the "Output" tab and enable "Side Chain Listen." 3. **Configure the Music Track:** Select your music track (e.g., Audio 2). Open its Dynamics panel, enable the Compressor, and set the "Side Chain" input to "Audio 1" — this tells the music compressor to listen to the dialogue track. 4. **Adjust Ducking Depth:** Set the music compressor's Threshold to around -20dB and Ratio to 4:1. Adjust the Attack (10ms) and Release (500ms). A faster attack ducks the music quickly when speech starts; a slower release brings the music back up gradually after speech ends. 5. **Fine-tune the Amount:** Adjust the music track's Makeup Gain so the music sits at a comfortable level during silence. When speech starts, the music will automatically lower by the amount defined by your compressor settings. Proper ducking is the difference between amateur and professional audio mixing. It ensures your dialogue is always clear while your music track maintains energy throughout the video. ## How do you speed up heavy audio workflows with Cutsio? Balancing dozens of individual audio clips manually in the Fairlight page is tedious and prone to human error. Professional editors avoid this by using AI pre-editing platforms like Cutsio to prepare their timeline before importing into DaVinci Resolve. The efficient workflow is: 1. Upload raw footage to Cutsio. The AI generates a free transcript and removes dead air automatically with the Silent Slicer. This eliminates the silent gaps that inflate timeline length and require additional audio trimming. 2. Use Semantic Search to find the best moments and assemble a rough cut using the transcript-based editing interface. 3. Export the rough cut as an XML timeline to DaVinci Resolve. The timeline populates with your original source files, complete with trim points and silence removal applied. 4. Once the timeline is locked and all content decisions are final, navigate to the Fairlight page. 5. Apply the Dialogue Leveler to the entire dialogue track at once, rather than normalizing individual clips on the Edit page. 6. Set up audio ducking for the music track in the Fairlight page. 7. Render the final mix. This workflow ensures you spend your audio editing time on the final mix, not on trimming silence, relinking clips, or rebuilding timelines. Cutsio handles the structural editing before Resolve touches the audio.

Lock your edit before you normalize audio.

Audio normalization in DaVinci Resolve is the final step — but you should never be normalizing clips that get cut from the timeline. Use Cutsio to assemble your rough cut, get client approval, and lock the edit. Then export XML to Resolve for Fairlight finishing on only the clips that survive.

## FAQ ### What is the difference between Peak and LUFS? Peak measures the absolute loudest fraction of a second in your audio clip — like a loud clap or microphone bump. Normalizing to True Peak ensures your audio never clips or distorts. LUFS (Loudness Units relative to Full Scale) measures the average perceived loudness over time. Streaming platforms like YouTube require -14 LUFS because it measures how loud the audio actually sounds to a human ear, not just a momentary spike. ### Why is my audio still quiet after normalizing? If your clip has one massive spike — a door slam, a cough, a loud noise — and the rest is quiet dialogue, normalizing to True Peak will only raise the volume until the spike hits -1dB. The dialogue will remain quiet. You must first cut out the spike with the Razor tool, or use a Compressor to squash the spike, then normalize the clip again. ### Can I automatically duck the music under the dialogue? Yes. On the Fairlight page, set up side-chain compression between your dialogue track and music track as described above. The music will automatically lower its volume every time someone speaks. ### What LUFS target should I use for YouTube? YouTube recommends -14 LUFS for all content. This is the loudness standard that YouTube's own audio processing expects. If you exceed -14 LUFS, YouTube may apply additional compression to your audio. ### Does Cutsio handle audio normalization? Cutsio's Silent Slicer removes dead air and can adjust overall volume, but final audio normalization to specific LUFS targets should be done in your NLE — in DaVinci Resolve's Fairlight page. By mastering the Normalize Audio Levels tool, the Fairlight Compressor, and the Dialogue Leveler plugin, you can guarantee your DaVinci Resolve projects sound professional, consistent, and perfectly balanced for any platform.
