CapCut: Audio normalization and noise reduction

Demo summary
The tutorial shows how to adjust volume via waveforms and apply AI features like 'Normalise loudness' and 'Reduce noise' to clean up audio.
Step-by-step
- Hover over the line near the audio waveforms in the timeline
- Drag the line up to increase decibels or down to decrease them
- Select the clip and navigate to the Audio tab in the top right panel
- Toggle on Normalise loudness to maintain consistent volume
- Adjust the Fade in and Fade out sliders
- Toggle on Reduce noise to remove background interference
Options
- Enhanced voice
- Video translator
- Separate audio
- Fill channel
Watch out for
- Avoid orange and red dots in the waveform; these indicate peaking where audio data is lost and sounds distorted
Tips
- Use the Reduce noise function specifically for videos with wind or background interference
- Apply Normalise loudness to ensure the clip stays at a consistent volume level
Highlights
“my voice sounds a lot more clear. The volume is nice and level”
