Enhance Audio in Video Online
Background Noise Removal lets you enhance audio in a video online in a couple of minutes. Upload your clip, choose a mode, and the AI makes the voice clearer and closer, removes background noise and echo, and evens out the volume. The picture stays exactly the same — only the audio track changes. No software, no manual EQ.
What You Can Improve in Video Audio
- Quiet, distant voice. Filmed on a phone a few meters away? Bandwidth Extension and Voice AutoEQ (keep noise) brings the voice closer and makes it fuller.
- Background noise. Traffic, wind, air conditioning, chatter — Voice Cleaner (remove music) keeps only the voice.
- Room echo. Empty apartments, offices and halls — the echo reduction mode removes the hollow sound.
- Uneven volume. Some phrases loud, others barely audible — Adaptive Leveler (keep noise) evens them out.
- Music covering the voice. Remove it completely or keep it and clean only the voice.

- Voice buried in street noise. Voice Cleaner (remove music) removes cars, wind and passers-by.
- Speaker shouts, then whispers. Adaptive Leveler makes all phrases equally loud.
- Breathing between phrases. The breath removal mode cleans it up without breaking natural speech.
- Lots of pauses and “uh”. Cut Filler Words, Coughs and Silence tightens the speech.
Why Video Audio Often Sounds Bad
Phones and cameras use small omnidirectional microphones that pick up sound from every direction. When the speaker is more than a meter away, the room and the street are almost as loud as the voice, and the voice loses low frequencies and sounds thin. The AI rebuilds the voice and separates it from the background, so the audio improves without re-shooting. Tips for your next shoot: how to improve voice in video without an expensive microphone.
