If the audio in your CapCut PC project sounds too low, you are not the only one facing it. Many creators get confused because the desktop version places audio controls differently from the mobile app. This guide explains three simple ways to boost audio in CapCut PC. You will learn how to adjust the volume slider, add keyframes for smooth volume changes, and manage audio levels through the waveform line.
Where Is the Volume Control in CapCut PC?
CapCut PC keeps its volume control in the right-side panel, not in a floating toolbar. You must select a clip first; the panel then updates to show that clip’s properties. Click the Basic tab in that panel to reveal the Volume slider and related options.
Volume can be adjusted independently for each clip type:
-
Video clip audio (sound embedded in your footage)
-
Background music tracks added from the media library
-
Voiceover tracks recorded inside CapCut
This per-clip approach means you can raise one quiet interview clip without affecting your background music at all.
Method 1: Adjust Volume Using the Slider (Quickest Way)
This is the fastest fix for a clip that is simply too quiet. The same steps apply whether you are working with a video clip’s embedded audio or a standalone audio track.
-
Open CapCut and load your project.
-
Click the clip on the timeline whose volume needs raising. The right-side panel will update to reflect that clip’s settings.
-
Select the Basic tab in the right-side panel. If the tab is not visible, confirm you have a clip selected rather than clicking on empty timeline space.
-
Drag the Volume slider to the right. The default is 100%; the maximum is 200%.
-
Press Play to preview and check how the adjusted level sounds in context.
-
Repeat for any other clips that need a boost.
Note: If your video clip has embedded audio but you only want to adjust a background music track, click the music clip on its own separate timeline row. Each track row operates independently.
Method 2: Use Audio Keyframes for Gradual Volume Changes
Use keyframes when you need volume to change smoothly within a single clip, such as fading in at the start, fading out at the end, or boosting only a specific portion of the recording.
-
Select the clip on the timeline and position the playhead on the particular portion of the audio track where you want to increase the volume.
-
Click the diamond (Add keyframe) icon next to the Volume control in the Basic tab of the audio settings of the selected track to add the keyframe. This places your first keyframe at the current playhead position.
-
Move the playhead to the timestamp where you want the volume to change.
-
Adjust the Volume slider to the new level. CapCut automatically places a second keyframe at that position.
-
Continue adding keyframes to shape the full volume curve across the clip.
To delete a keyframe, click it on the timeline to select it and then click on the blue diamond (add keyframe) next to the Volume slider in the Basic tab. To shift its timing, drag it left or right along the timeline.
Method 3: Use the Volume Adjustment Handle/Waveform Line
For each audio track on the timeline, you will see a white horizontal line running throughout the track. It is called the waveform line or the volume adjustment handle. It lets you increase or decrease the volume of the entire track. Here's how you do it.
-
Click on the track to select it.
-
Bring your cursor to the waveform line. You will notice that the cursor changes to the volume drag tool (up and down arrows) and the line gets highlighted.
-
Click and hold the waveform line and slowly drag it up to increase the volume of the entire track.
Pro Tip: Why Is My Audio Still Too Low After Boosting?
If you have maxed out the slider and the audio still sounds quiet, a few things could be working against you:
-
The source recording was too quiet: A mic positioned too far from the speaker, or a recording device with low input gain, produces weak audio that post-production can only partially fix.
-
Background noise is masking the voice: Room noise makes quiet speech harder to perceive even after a boost.
-
CapCut’s 200% ceiling is not enough: If you need more volume, copy the audio clip first. Place the duplicate on a track above the original. Playing both tracks together can make the audio sound much louder. Be careful with very high volume levels. And listen to a preview to check for distortion or clipping.
If low-volume audio is a recurring problem across your projects, it almost always points to the recording stage rather than the edit. A compact wireless mic like the Hollyland LARK M2, which weighs just 9g and runs up to 40 hours on a single charge, captures cleaner and louder source audio from the start, reducing the amount of boosting you need in post.
Frequently Asked Questions
Can I increase volume above 200% in CapCut PC?
CapCut’s Volume slider caps at 200%. To push beyond that limit, duplicate the audio clip and place the copy on a second timeline track directly above the original. Both clips play together, raising the perceived loudness further. Be aware that stacking very high-volume clips can cause distortion, so listen carefully before exporting.
How do I increase volume for background music separately from my voiceover?
Click your background music clip on its own timeline track and adjust that clip’s Volume slider independently. The voiceover stays on its own track and does not change.
Why does my video have no sound in CapCut PC?
Check a few basic things first. Make sure the clip’s Volume slider is not set to zero. Look for a muted speaker icon on the timeline track and turn it back on if needed. Also, confirm the original video file includes audio before importing it. CapCut cannot add sound to a video that was recorded or exported without any audio.
Conclusion
We now have three methods to fix quiet audio in CapCut PC. The volume slider gives a quick flat boost to sound levels. Keyframes allow smooth fades and precise volume shaping over time. You can also raise the volume using the volume adjustment handle. Before exporting, play everything at normal listening volume. Check clips that still sound uneven during review.
