![]() ![]() With all the technology available today, there is no excuse to hear microphone hiss in any professional recording.įirst, you really need low noise equipment to start with. Processing and reducing noise should be part of the work flow of editing sounds. From my experience with recording natural soundscapes for over 20 years, I would like to share my technique for eliminating background equipment noise. People have asked us over the years what is the best technique for reducing background noise from audio recordings. Let us know if you have any questions.Technique for Eliminating Equipment Noise ![]() Refer to this page to explore the other videos of this series. Hope it helps in understanding restoration and noise reduction techniques in Adobe Audition. Hiss Reduction effect (Waveform Editor only) Refer to these links to learn more about the other noise reduction effects. You can also use other effects to reduce specific types of noise. These are a few of the main techniques used for noise reduction in Audition. Please note that this effect only works in the Waveform Editor and is unavailable in the Multitrack editor. Adobe Audition gathers statistical information about the background noise and then removes it from the remainder of the waveform.Įffects > Noise Reduction/Restoration > Noise Reduction Here you extract a noise profile from a selected range, indicating only background noise. This method is preferable for removing any noise that is constant throughout a waveform. This effect can remove a combination of noise, including tape hiss, microphone background noise, and power-line hum. This Noise Reduction effect dramatically reduces background and broadband noise with a minimal reduction in signal quality. Learn more about Spectral Frequency Display 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. Here you can visually draw a selection over the desired frequency components and remove it or make it more pronounced. Spectral Frequency Display allows you to visually edit the audio. Noise reduction using Spectral Frequency Display Using DeNoise effect can reduce the volume level which can be compensated by increasing the levels using the Gain slider.Įffects > Noise Reduction/Restoration > DeNoise This effect provides a simple slider that controls the amount of noise reduction ranging from 0% to 100%. High Pass filter can be applied using Parametric Equalizerīackground or surrounding noises can be reduced or removed by using the DeNoise Effect. You may also adjust the Gain to control the slope or the intensity at which lower frequencies are filtered out.Įffects > Filter and EQ > Parametric Equalizer While using this filter you need to specify the cutoff point at which the frequencies are removed. High Pass filter can be used to remove it as it allows the higher frequencies to pass through and removes the lower frequencies. Generally, wind rumble consists of lower frequencies. Learn about the different tools used in this video ![]() 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.Ġ:16 - Removing wind rumble background noiseĠ:40 - Parametric equalizer high pass filter for wind noise reductionĢ:35 - Removing background noise after wind removalĤ:39 - Enhancing mouth clicks with compressionĥ:00 - Audio restoration in spectral frequency displayĨ:07 - Using noise reduction instead of DeNoiseĨ:55 - Using the noise reduction (process) effectġ0:17 - High pass filter to eliminate rumble and humġ1:00 - Using the dynamics effect to introduce a noise gateġ2:09 - Audio before noise reduction and conclusion ![]() Let us know how you use Audition & what you want to learn about Adobe Audition. We've some interesting articles & videos coming up weekly where we will talk about the tools, workflow & some really cool effects. This is a part of the ongoing Learn series with Mike Russell which will help you get started with Adobe Audition. ![]()
