Remove Hiss from Audio: Ultimate Guide 🔍

Like the question posed by SzakaRosa on Reddit, many individuals, whether you are a photographer, producer, or sound engineer, may inadvertently record audio hisss. These sounds are often not intentionally created and most commonly stem from electronic components. The amount of hiss depends on the quality of the electronic components, meaning that lower-quality equipment will produce more hiss compared to well-manufactured devices.

Poor-quality audio cables can also result in buzzing during recordings. While hiss may be unavoidable during the recording process, fortunately, many audio editing software offer methods to reduce and eliminate hiss from audio. The following content will present how to use five tools to eliminate or reduce this type of noise.

After our comparison test, we came up with the following table.

After downloading and installing Adobe Premiere Pro, you can learn how to edit and eliminate audio hiss by following the steps below.

Step 2. Within the project panel, access "Effects" > "Noise Reduction/Restoration" > "Denoise."

Audacity's Noise Reduction, Silence tool, low-pass filter, and Notch Filter can assist in reducing hiss sound or removing breathing from video. As the questioner mentioned above, it's highly possible that you may not achieve high-quality audio results after using a specific tool. Therefore, we recommend trying these three methods.

Please remember that Audacity is a destructive editor, meaning any changes made to your project will be permanently saved within the audio file. So, be sure to create a copy of your original audio before using it for editing.

Alright, let's now proceed to remove the hiss from your audio.

Using Its Noise Reduction

This tool can reduce all kinds of noise in the audio, such as traffic, human voices, hiss, echo cancellation, electrical rumbling, and buzzing.

Step 1. Open Audacity and import the audio file.

Step 2. Highlight the blank space of the file and then click "Effect" > "Special" > "Vocla Reduction and Isolation."

Step 3. Click "Get Noise Profile."

Step 3. Click Ctrl + A to select your entire file. Then click "Effect" > "Noise Removal and Repair" > "Noise Reduction..." > Click "OK."

Step 4. Preview the audio.

Using Its Silence Tool

If your hiss only appears in quiet parts of the track, you can use Audacity's mute tool to remove background noise from audio.

Step 1. Play the audio and find the hiss part.

Step 2. Select the hiss part by using the selection tool.

Step 3. Go to the menu bar "Generate" > "Silence."

Step 4. Preview the changes and then click "Generate" to eliminate the hiss.

Using Its Low-Pass Filter

A low-pass filter effectively reduces sounds above a specific frequency, making it useful for eliminating high-pitched sounds in an audio clip.

Step 1. Select the whole audio track and then click on "Analyze" > "Plot Spectrum…"

In the Frequency Analysis, you can observe a graphic. Hiss sounds tend to be on the higher frequencies, so check on the right side of the graphic. A peak in the graph indicates a high pitch at that frequency. Take note of this frequency and then close the window.

Step 2. Select the track and navigate to "Effect" > "Low-Pass Filter." Input a value lower than the frequency you wish to diminish.

Step 3. Preview and click "OK" when you like the result. After finishing these steps, you could enhance the audio quality greatly.

With Audition

Step 1. Import the audio file into Audition and choose the section that contains only the hiss.

Step 2. Tell it what the noise is: highlight that area, then go to "Effects" > "Noise Reduction/Restoration" > "Capture Noise Print."

Step 3. Proceed to "Effects" > "Noise Reduction/Restoration" > "Adaptive Noise Reduction."

Step 4. Adjust the settings for "Reduce Noise By" and "Apply" to preview the changes.
