De-wind [ADV]

Overview

De-wind removes intermittent low frequency rumble that can occur when light to moderate bursts of wind come into contact with a microphone diaphragm. De-wind is not designed to remove heavy wind bursts that blow out and distort a microphone signal.

Controls

De-wind module

  • REDUCTION: Determines the balance between the depth of wind reduction and the preservation of the original signal.
  • CROSSOVER FREQUENCY [Hz]: Sets the upper frequency limit for the De-wind processing algorithm.
  • FUNDAMENTAL RECOVERY: Re-synthesizes lower voice harmonics that may be lost or obscured by wind.
  • ARTIFACT SMOOTHING: Eliminates “musical noise” that is often characteristic of FFT-based processing. Musical noise can be described as how something may sound underwater. Increase this slider if your output sounds watery, but decrease it when too much smoothing makes speech sound muffled.

When to use the De-wind Module

The De-wind module is​ best​ ​suited to remove and reduce intermittent wind noise in the foreground (for example, a recording with periodic wind gusts that come into direct contact with the diaphragm of the microphone) as opposed to constant wind noise in the background.

The De-wind algorithm attempts to preserve the noise floor of a recording by tracking how it changes over time. Specifically, De-wind is looking for noise floor changes that are characteristic of the noise introduced when a burst of wind comes in contact with the diaphragm of a microphone. If the wind in your recording is constant or in the background, De-wind will treat it as part of the desirable noise floor and will preserve it rather than remove it.
