Wind Noise Remover

You Might Also Need

Wind Noise Remover deletes the sub-100 Hz rumble that gusts of wind put into a microphone, with a single 12 decibel per octave highpass and a corner you choose. Wind is almost pure low-frequency energy, so this is one of the few repairs that costs the voice nothing.

What is Wind Noise Remover?

Load a recording, drag the corner frequency and the tool applies one highpass filter to every channel. Wind noise is concentrated well below a hundred hertz, while speech and most musical content are not, which is the gap this filter is built to sit in. Rumble below the corner rolls off quickly, content an octave above it passes effectively untouched, and the report tells you both figures so you can see exactly where the line was drawn.

What you set and what you see:

  • A corner frequency from 40 to 400 Hz in steps of 10, defaulting to 150.
  • A second order highpass, which is a 12 decibel per octave roll off rather than a brick wall.
  • A report line quoting the corner, the slope and the frequency above which content is effectively untouched.
  • Panel guidance suggesting a start of 80 to 150 Hz and noting that male broadcast voices reach down to about 85 Hz.
  • A WAV download named after the source with a dewinded suffix.

The filter is a second order biquad highpass built from the standard RBJ coefficients with a Butterworth damping factor, which places the response 3 decibels down at the corner and then falls at 12 decibels per octave below it. The measured behaviour is that a 60 Hz component is knocked down by more than eighteen decibels at a 300 Hz corner while a 500 Hz tone passes untouched. That is the useful shape for wind: gusts inject energy concentrated well below a hundred hertz, while the lowest notes of most voices sit around the eighty to one hundred hertz region, so a corner placed carefully sits in the gap between the two. Unlike the spectral repairs, this filter has nothing to estimate and no artifact to introduce, which makes it safe on any material that genuinely has no useful sub-bass.

Where it stops being the right tool:

  • Once the corner is set above the fundamental of a male voice, the low end of speech starts to thin out audibly.
  • It cannot repair the distortion a violent gust causes above the rumble, because that clipping is permanent and beyond any filter.
  • If the recording carries music with real bass content, the filter removes that bass along with the wind.
  • The roll off is shallow, so noise an octave or more above the corner survives.
  • It treats the whole file, including passages with no wind at all, so the low end is affected everywhere.
  • There is no preview inside the tool, so the corner is chosen before you hear the result.

Use it on field recordings, phone interviews, outdoor vlogs and any take where the microphone was exposed, and choose the corner by asking what the material actually needs down low. For a male broadcast voice, 80 to 120 Hz usually clears the rumble while leaving weight behind; for speech with no low-frequency interest at all, or for material you are going to highpass again later in the chain, going higher is harmless.

How to use Wind Noise Remover

  1. Load the recording and start with a corner between 80 and 150 Hz.
  2. Check what the material needs below the corner; a male voice can go down to about 85 Hz, so leave room beneath it.
  3. Click Remove wind rumble to run the highpass across every channel in one pass.
  4. Download the dewinded WAV and confirm the voice still has weight before accepting the setting.

When to use Wind Noise Remover vs related tools

Wind Noise Remover is the one-pass answer when low-frequency rumble has taken over a recording and nothing musical lives down there. Plosive Remover is the targeted version of the same idea for speech, acting only on the syllables that blast rather than filtering the whole file. When the low-frequency problem is a steady electrical tone rather than wind, Hum Remover removes it by frequency, and DC Offset Remover fixes a waveform whose centre has drifted. Hiss Remover covers the opposite end of the spectrum.
