Which Videos Can You Clean? What We Measured

We tried real clips from a street, a room, a lecture and a hall. You remove background noise from video best when one person talks and the noise sits behind them.

  • Street and outdoor interviews

    We used Full to remove background noise from video shot on a New York street, with a crowd about 5 dB below the speaker. Quiet moments went from -15 dB to -48 dB, and 48 of 51 words stayed.

  • Talking-head videos and vlogs

    Fans and air conditioning are the easiest case to remove background noise from video. In an indoor interview the pauses fell from -39 dB to -53 dB, and every word stayed.

  • Lectures and screen recordings

    Projector and room hum stay the same for an hour, so it is simple to remove background noise from video lessons. On a chemistry lecture the hum dropped about 39 dB with no words lost.

  • Speeches in a big hall

    Echo and a crowd can sound like speech to the tool. On a hall speech, Full cut the first sentence short. Gentle kept all 48 words and still lowered the room by about 16 dB.

The video file stays with you

These are the sound tracks of three real videos. Press play to hear how we remove background noise from video, then switch versions. The hall speech used Gentle.

    Traffic and a crowd behind the speaker. Full pushed the street back so the voice leads.

  • Interview filmed indoors

    A steady room noise under a calm voice. We used Full to remove background noise from video like this: the pauses went close to silent and every word stayed.

  • Speech in a hall, on Gentle

    Cheering and echo around a speaker. Gentle kept the whole speech, where Full lost the opening words.
