Nothing ruins a great video or podcast like a constant hissing sound in the background. This persistent static, hiss, keyboard clicks, or even background dog barks, known as white noise, can make your content sound unprofessional and distract your audience. If you are seeking for how to remove white noise from audio, you've come to the right place.
In this post, we will walk you through how to remove white noise using different tools. Just follow the step-by-step tutorial to remove unwanted white noise and achieve clean, high-quality audio.
What Is White Noise?
White noise is a type of random, static-like sound that contains all audible frequencies at equal intensity. It's often heard as a continuous hiss in the background of recordings. The most common causes of white noise in audio are:
- Microphone Self-Noise: The subtle electronic hiss produced by the microphone's internal components.
- Ambient Noise: The faint, constant sound of a room, such as an air conditioner, computer fans, or a refrigerator.
- Electronic Interference: Hissing or static caused by poor-quality cables, ground loops, or other electrical issues.
While not as jarring as a sudden buzz or a pop, white noise is a consistent irritant that can be difficult to remove without the right tools.

How to Remove White Noise in Aiarty Video Enhancer?
Step 1. Import Your Video
First, download and install Aiarty Video Enhancer. Once it’s running, simply drag and drop your video file(s) that suffer from unwanted white noise directly into the application.
Step 2. Activate and Refine Audio Denoise
Check the box next to Audio Denoise to enable this powerful feature. Now, you can fine-tune the settings for optimal white noise reduction:
- AI Model: For the best white noise reduction results and speech clarity, choose VoiceFliter V3.0.
- Noise Attenuation Limit (dB):
- Post-Filter Threshold:
For significant white noise, begin by setting this between 18-24 dB. This level helps substantially reduce pronounced reverberation; If the white noise is more subtle, aim for a lower range of 6-12 dB to ensure your audio sounds natural, not over-processed.
With moderate white noise or if a slight hiss persists, a higher threshold (0.03-0.05) can be beneficial for a cleaner sound; For lighter white noise or when you want to retain more of the natural room ambiance, a lower threshold (0.01-0.02) should be sufficient.
Step 3. Export the Clean Video
Once your settings are dialed in, simply click Export Current to save your single video, or choose Batch Export if you're processing multiple files. Your newly saved video will feature clear, hiss-free audio.

2. Remove White Noise with Audacity (Free but Manual)
Audacity is a free, open-source audio editor that’s been a go-to for audio professionals and hobbyists for years. While it requires a bit of a learning curve, its powerful features make it an excellent choice for removing white noise, and the price is unbeatable.
How to Remove White Noise with Audacity?
Step 1. Import the Audio File
Download and install Audacity. Once the white noise remover is open, navigate to the top menu bar, select File > Import, and choose the audio file you want to clean.
Step 2. Create a Noise Profile
Next, you need to highlight a section of your audio that contains only the white noise (no voices or instruments). Go to Effect > Noise Removal and Repair > Noise Reduction. Then click and drag over the waveform to choose it.
With that section highlighted, go to the Effect menu at the top, choose Noise Removal and Repair and select Noise Reduction. In the Noise Reduction window, click Get Noise Profile. This action tells Audacity to analyze the selected sound sample and create a digital "fingerprint" of the noise you want to eliminate. The window will then automatically close.
Step 3. Remove White Noise from Audio
Now that Audacity understands your specific white noise, it's time to apply the white noise reduction to your entire audio. Select the full audio track by double-clicking on the waveform, then go back to back to Effect > Noise Removal and Repair > Noise Reduction. In the Noise Reduction window, you'll need to adjust the following key parameters to effectively remove the white noise from your audio file:
- Noise Reduction (dB): This slider determines how much of the noise you want to remove. Start with a lower value (around 12 dB) and increase if needed. Be careful not to set it too high, as it can make your audio sound robotic or distorted.
- Sensitivity: This affects how precisely the algorithm targets the noise
- Frequency Smoothing (bands): This helps to reduce artifacts.
Step 4. Export the Audio
Click on Preview to listen and check if the background white noise is sufficiently reduced. Once you’re happy with the sound, click OK. Audacity will then apply the white noise removal across your entire track. Then go to File > Export and choose your desired file format, such as MP3 or WAV.

What Causes White Noise in Audio?
Understanding the source of the problem is the first step to finding the right solution for white noise removal. While the hissing sound is often simply called "white noise," it can originate from various sources. Knowing the cause can help you not only fix the current issue but also prevent it in the future.
- Microphone Self-Noise: Every microphone generates a small amount of internal electronic noise. This "self-noise" is more noticeable on lower-quality microphones or in a very quiet recording environment.
- Electronic Hum & Hiss: This is one of the most common causes of white noise in audio. It often comes from electrical interference (e.g., from power cables, fluorescent lights, or your computer's fan). A poorly shielded cable or a grounded outlet can introduce a steady hum.
- Poor Gain Staging: If your microphone's input gain is set too low and you have to boost the volume significantly in post-production, you'll also amplify any inherent background noise, leading to that audible hiss.
- Interference from Wi-Fi or Bluetooth: Wireless signals can sometimes interfere with your audio cables, causing subtle buzzing or static that acts as a form of white noise.
Best Practices: Prevention is Key!
The most effective way to handle white noise from audio is to stop it from getting into your recording in the first place. A great white noise remover is a last resort, not a first-line defense. Here are some actionable tips for cleaner recordings:
- Optimize Your Recording Environment: Record in a quiet space away from noisy appliances like refrigerators, air conditioners, or buzzing lights. Using acoustic foam panels can also help reduce echo and external noise.
- Position Your Microphone Correctly: Get your microphone as close to the sound source (e.g., your mouth) as possible. This improves the signal-to-noise ratio, meaning your voice is much louder than the background noise.
- Check Your Cables: Use high-quality, shielded cables to prevent electrical interference. Make sure all connections are secure and that you are not running audio cables parallel to power cables.
- Set Your Gain Levels Correctly: Adjust your microphone's gain so that the input signal is strong without "clipping" (distorting). A good rule of thumb is to aim for a level of around -12 dB on your recording meter.
