Method 2: Using Noise Gate for Noise Removal in Adobe Audition

The Noise Gate effect is the perfect plugin to remove subtle background noise like hums, hisses, and faint sounds between louder sections.

If you don’t want to risk audio quality in your content, use Noise Gate and set a threshold level. You can reduce or mute sounds below this threshold, allowing the louder sound to pass through. Here is how you can do it:

Step 1: Go to Effects > Amplitude and Compression > Dynamics.

Step 2: Select the AutoGate option and uncheck the others. Set the Threshold and Attack levels and click Apply.

Method 3: Reducing Noise in Adobe Audition With an Equalizer

Equalizer in Adobe Audition lets you target specific frequency ranges to reduce undesired sounds in your audio. It can reduce resonances and low-frequency and high-frequency noise. Its primary function is to adjust tonal balance and shape the frequency response of your audio.

This tool is perfect for eliminating low-end background noise. It lets you choose from one, one-half, and one-third of an octave.

Here are the steps to reduce noise with an Equalizer tool in Adobe Audition:

Step 1: Double-click your audio file to activate the Waveform view. Go to Effects > Filter and EQ > Graphic Equalizer.

Step 2: Adjust the equalizer bands and click Apply.

Method 4: Adobe Audition Noise Reduction With the Dynamics Effect

Besides adjusting AutoGate, you can explore the other dynamic parameters: Compressor, Expander, and Limiter.

The Compressor reduces the audio’s dynamic range, the Expander increases it, while the Limiter does the same to the audio that exceeds a specified threshold.

These effects are perfect for users who want to fine-tune their recordings by reducing noise during quieter sections and enhancing the audio quality of their recordings.

Here’s how to reduce noise with the dynamic effects:

Step 1: Go to Effects > Amplitude and Compression > Dynamics.

Step 2: Select the Compressor, Expander, and Limiter and set their Threshold and Ratio levels. You can additionally set the Attack, Release, and MakeUp levels under Compressor. Click Apply.

Method 5: Reducing Noise in Adobe Audition With Hiss Reduction

If you are dealing with high-frequency noise (or a noise floor) in your audio, you can fix it with the Hiss Reduction feature in Adobe Audition.

This feature targets and eliminates high-frequency noise in recordings due to microphone self-noise, electrical interference, or analog tape hiss. Here is how to apply it in your recordings:

Step 1: Open your audio recording and go to Effects > Noise Reduction/Restoration > Hiss Reduction.

Step 2: Sample your hiss with the Capture Noise Floor function. Control your noise removal effect using the sliders until you like the results, and click Apply.

Method 6: Use the Adaptive Noise Reduction in Adobe Audition

Another option to reduce unwanted sounds from your audio is through the Adaptive Noise Reduction effect. This Adobe Audition feature can tackle complex noise scenarios, such as varying background sounds that change over time, like wind and ambient noise.

The Adaptive Noise Reduction effect can pick up low sounds and isolate excessive bass. Here’s how to apply it:

Step 1: Double-click your audio file to activate the Waveform. Then, go to Effects > Noise Reduction/Restoration > Adaptive Noise Reduction.

Step 2: Adjust the Reduce Noise By, Noiseness, and Spectral Decay Rate parameters. Select Apply when you like the results.

Method 7: Reducing Noise in Adobe Audition With the Noise Reduction Feature

The Noise Reduction feature in Adobe Audition is an advanced tool for precisely controlling unwanted noise in your audio recordings. Its primary target is noise like hums, hisses, rumbles, and ambient sounds.

This tool can clean up audio tracks and produce professional results, like high-production tracks. It can be tricky for beginners, but you will remove undesired sounds from your content if you follow our steps:

Step 1: Open the audio you want to edit in Adobe Audition and go to Effects > Noise Reduction/Restoration > Capture Noise Print. That way, you can get a background noise sample as a reference for the noise reduction tool. Choose a specific section or hit Ctrl + A (or Command + A on a Mac) to select the entire audio file.

Step 2: Return to the Effect tab and choose Noise Reduction under Noise Reduction/Restoration.

Step 3: Adjust the Noise Reduction and Reduced By parameters. Preview the changes and click Apply.
