This is a part of the ongoing Learn series with Mike Russell which will help you get started with Adobe Audition. We've some interesting articles & videos coming up weekly where we will talk about the tools, workflow & some really cool effects. Let us know how you use Audition & what you want to learn about Adobe Audition. We're here to help.





In this video, you will understand how to use different tools in Adobe Audition to remove various types of noises like wind noise, ambient noise, statics, and mouth clicks.

Learn about the different tools used in this video


High Pass filter

Generally, wind rumble consists of lower frequencies. High Pass filter can be used to remove it as it allows the higher frequencies to pass through and removes the lower frequencies. While using this filter you need to specify the cutoff point at which the frequencies are removed.

You may also adjust the Gain to control the slope or the intensity at which lower frequencies are filtered out.
Effects > Filter and EQ > Parametric Equalizer
High Pass filter can be applied using Parametric Equalizer


DeNoise effect

Background or surrounding noises can be reduced or removed by using the DeNoise Effect.
This effect provides a simple slider that controls the amount of noise reduction ranging from 0% to 100%. Using DeNoise effect can reduce the volume level which can be compensated by increasing the levels using the Gain slider.

Noise reduction using Spectral Frequency Display

Spectral Frequency Display allows you to visually edit the audio. Here you can visually draw a selection over the desired frequency components and remove it or make it more pronounced.

You can also use the Spot Healing Brush tool in Spectral Frequency Display to paint the areas of sound that you would like to remove and Audition automatically cleans that part of the audio.

Noise reduction using a Noise Print
This Noise Reduction effect dramatically reduces background and broadband noise with a minimal reduction in signal quality. This effect can remove a combination of noise, including tape hiss, microphone background noise, and power-line hum.
This method is preferable for removing any noise that is constant throughout a waveform.

Here you extract a noise profile from a selected range, indicating only background noise. Adobe Audition gathers statistical information about the background noise and then removes it from the remainder of the waveform.

Please note that this effect only works in the Waveform Editor and is unavailable in the Multitrack editor.

These are a few of the main techniques used for noise reduction in Audition. You can also use other effects to reduce specific types of noise. Refer to these links to learn more about the other noise reduction effects.

Sound Remover effect   

Adaptive Noise Reduction effect 

Automatic Click Remover effect 

Automatic Phase Correction effect 

Click/Pop Eliminator effect 

DeHummer effect 

DeReverb effect 

Hiss Reduction effect (Waveform Editor only)


Hope it helps in understanding restoration and noise reduction techniques in Adobe Audition. Refer to this page to explore the other videos of this series. Let us know if you have any questions.
