How to Increase Video Volume Online
Make the Audio in Your Video Easier to Hear
Increase the Overall Volume
Turn up the audio across your entire video when the original recording is too quiet. Adjust the Volume or Gain control while listening to the result, so voices, music, and other sounds are easier to hear without changing the video itself.
Make One Section Louder
Split the video around a quiet section and adjust that part separately. This is useful when a speaker moves away from the microphone, one scene was recorded at a lower level, or only part of the video needs a volume change.
Adjust Each Audio Track
Set the volume of voiceovers, music, and sound effects separately when your project includes several audio tracks. Raise a quiet narration, lower music beneath speech, or make an effect easier to hear without changing everything else in the video.
Change the Bass and Treble
Use the equalizer presets to bring out bass, treble, or speech, or adjust individual frequencies yourself. This gives you more control over how the video sounds when increasing the overall volume is not enough.

Why Use Flixier to Increase Video Volume
Clean Up Speech
Use Flixier’s audio enhancer to reduce background noise and reverb, make speech clearer, and even out the volume. This can make a quiet recording easier to understand before you increase its overall level.
Add Music and Sound Effects
Use Flixier to add music to your video, then set its volume beneath dialogue or narration. You can also add sound effects from the stock library and use fades to make each track enter or end naturally.
Record a Clear Voiceover
Record a new voiceover when the original speech is too quiet, unclear, or incomplete. Add the narration to the timeline, line it up with the video, and adjust its volume separately without replacing the original footage.
Turn Speech Into Subtitles
Transcribe audio and use it to add subtitles to your video. Review the text, correct any mistakes, and adjust the font, size, color, and position before exporting the finished video.

Still have questions?
We got you!
How do I increase the volume of a video online?
Import your video into Flixier and select it on the timeline. Open the Audio settings, then move the Volume or Gain control until the sound reaches the level you need, then listen to the result before clicking Export and saving the louder video to your computer.
Can I make only one part of a video louder?
Yes, you can split the video at the beginning and end of the quiet section, then select that part and increase its volume separately. This lets you fix a low-volume sentence, scene, or speaker without making the rest of the video unnecessarily loud.
Can I reduce the volume of a video in Flixier?
Yes, the same Volume control can be used to lower audio that is too loud. You can reduce the volume of the entire video or split out a particular section and adjust it separately, which is useful for loud music, sound effects, or sudden volume changes.
How can I make speech easier to hear in a video?
Increase the recording’s volume and use Enhance Audio to reduce background noise and reverb, clarify speech, and even out the overall level. If your project contains separate voice and music tracks, lower the music beneath the speaker instead of raising every sound in the video.
Can I boost the bass or treble in a video?
Yes, Flixier includes equalizer presets that can bring out bass, treble, or speech. You can also adjust the frequencies yourself when you need more control, then preview the result as you work to make sure the changes improve the audio without overpowering voices or other important sounds.
