Mastering the Art of AI-Based Signal Denoising

How to DeNoise AI

There have often been times when we took some photo or video with our mobile phones or digital cameras, but we found out later that the clip contained hiss, some compression or particles. Everyone, especially in this digital world, is trying to make their content as clean as possible, without impurities, for the audiences to watch, enjoy, and stay with the creators. So, you might find it really uncomfortable when you are in this kind of situation. But what you can do, is doable – you can depend on a video denoise software!

There are a lot of online or offline tools you could use to do that, and we have discussed a lot of them on our web-site, and now, we will review yet another way to achieve your desired result when it comes to noise and grain. So, in today’s article, we will touch upon how to AI DeNoise your image!

The case with this intelligent noise reduction for 2022 is that noise reduction software has been the same for over a decade. This is when DeNoise AI comes to play, because its approach is something new – it uses deep learning. The process is lengthy and focuses on learning millions of images, thus let DeNoise AI to accurately distinguish between real image detail and noise. This is so important because with this new technique, now it is possible to denoise images while actually recovering important detail, something that was impossible a few years ago.

Topaz DeNoise AI has a very simple and intuitive interface with different noise removal options. Anyway, using it in the most effective way would require some knowledge. Oh, and, it would be a headache if you have a slow computer!..

So, as mentioned, traditional noise reduction software most of the time reduces the original detail in the images, but DeNoise AI’s noise reduction eliminates noise, meanwhile, preserves the detail and even enhances it. The new update of Topaz DeNoise AI offers different advanced DeNoise AI Models that can be integrated perfectly into your workflow; you can use it as a standalone piece of software or as a plugin for Adobe Photoshop or Lightroom.

How to AI DeNoise a file

Let’s just suppose you don’t have the software. So, download and install Topaz DeNoise AI. Go to Topaz Labs and select your operating system: Windows or Macintosh OS. Then, install the program.

Once the installation is finished, you will be able to see the Topaz DeNoise AI icon among your applications. Topaz DeNoise AI plugins for Lightroom or Photoshop would also be added there automatically, without any further intervention. But, if that is not the case, it’s ok to add them manually.

The first time you open Topaz DeNoise AI, you can either log in with your Topaz Labs account or try the Denoise AI 30-day free trial.

So, let’s discover how to use DeNoise AI in its different versions!

First, how to remove digital noise with DeNoise AI: DeNoise AI supports most of the commonly used photography files like raw files, dng, tiff, jpegs, etc. So, open the program, drag or open your image and select the best AI model.

In the upper right corner, you will find a toolbar with these options:

Preview Options:

To change the view mode of the photo you’re working with, you can select:

Original (original photo preview)
Single (denoised photo preview).
Split (Original and denoised photo preview with a split slider)
Side by Side ( Original and denoised photo preview)
Comparison ( Compare how the different Ai Models work in your photos at the same time).

Zoom

Zoom in on your images to accurately check the process’s progress.

Denoise AI full review and tutorial

On the right side, you’ll find:

A navigator with the selected zoom box.
A list with the following DeNoise AI Models:
Standard: Broadly developed noise reduction that maintains detail.
Clear: Best for photos with smooth and rounded surfaces such as skin, rocks, water, etc.
Low light: Best for low-light conditions and heavy noise
Severe noise: Best for extremely noisy photos
Raw: The newest AI model in DeNoise. It provides excellent noise reduction, preserving detail, and authentic color starting from a RAW file.
Main Settings. The Auto mode works great in most situations. However, it can be pretty aggressive and give your photos a washed-out look. With Manual Mode, you can set the adjustments according to your taste.
The Post-processing sliders help reduce any color noise remaining in your photos and preserve original detail.
Save Image: To set your output settings before saving your images.

Then, adjust the setting sliders (you can just select Auto mode here); now, apply the adjustments locally, if necessary, using the mask tool; and, save the file with the output settings selected.

Second, let’ts move to DeNoise AI workflow.

If you are trying to find the simplest way to start with DeNoise Ai, it’s better to use the suggested mode, - Light bulb icon! This will automatically select an AI model, and will do so based oon your image. Anyway, in order to remove digital noise there, it’s the best to use the updated comparison view. The reason is obvious – you can take a look right away and compare varied AI models, or the same ones with some different settings to your liking.

So, how to do just that? Well, select the AI model and fine-tune the adjustment using the following settings:

Remove Noise: This slider is wonderful!. It removes the noise in your photo, but doesn’t kind of wash out the images. Values between 10-50 are the best in most cases.
Enhance Sharpness: It sharpens and recovers the detail in images that may become a bit blurry after denoising. It would be excessive if you set the values over 30, in case you would like to avoid odd textures.

After that, you can refine your results with these DeNoise AI Post-processing adjustments:

Recover Original Detail: It helps recover some detail that has been washed out after the noise reduction and adds a bit of grain to keep the image natural. 20-40 points is more than enough.
Color Noise Reduction: This is a powerful tool that reduces any color noise remaining in your images. Zoom in on a dark area and adjust the slider until the color noise disappears and you are happy with the result!

And, the last topic to discuss is DeNoise AI Masking Tool! The software includes a very simple Mask tool in case you want to denoise the image only in certain areas and not in others. So, the key here is that DeNoise AI will apply your adjustments only to the areas that you paint in red.

You need to ckeck the Overlay tool to see the red color while painting. When you are satisfied with the areas you panted, After painting over these areas, you will see a preview of your mask in black and white. Here, white shows the adjustments while black hides them. Following this, DeNoise AI will just be applied to the areas painted in white.

And, the masking settings are:

Add/Subtract: to paint in white or black and reveal or hide your adjustments.
Size: to change the size of your brush.
Softness: to change the hardness of your brush. Being 0 is the hardest and 100 the softest.
Opacity: to vary the opacity of the mask to add precise local adjustments.
Mask options: to clear or invert your mask.
Overlay: to show in red these areas where you are painting.

Once you finish creating your mask, just click on the “apply mask” button, and there you go!

Part 1. Audio Hiss: What is it and Why Remove it

A hiss is a broadband noise across the audible spectrum of your audio. It becomes more intense in high frequencies, affecting the quality of the vocals and instrumentals in your audio. A hiss could sound like blue noise and is often caused by the electronic components themselves, which is referred to as self or inherent noise.

A hiss is measured by decibels and is usually difficult to avoid because it is produced by electronic components. You will usually hear the hiss as air that is getting out of a narrow passage. You may also hear a reverb, which is a sound that occurs in space and sends sound waves out in all directions. Since this is a component of the original recording, it is impossible to delete it. However, hiss reduction is possible with the right editing software.

Causes of Hiss in Audio Recordings

Electronic components such as microphones, video cameras, and interfaces create self-noise because of the heat energy created by the moving parts
Audio circuits generate self-noise, with the noise floor being the level of the inherent noise in the circuit
Screening and quality of electronic components, which cheap and poorly made equipment producing more hiss
Poor-quality audio cables contribute to hiss and hum when they are picked up during recording

Importance of Removing Hiss for a Professional Sound

Removing hiss from audio is important for a professional sound because it makes the sound clearer and polished. The polished sound leads to

Improved clarity and focus on the main vocals or instruments in a recording sound
A more professional and smooth sound
Increases listener engagement
More understandable vocals and more vibrant instrumentals

Part 4. Tips and Tricks to Avoid Hiss and Reverb Noise

The problem of hissing sound and reverb noise usually comes from the equipment itself. However, some background noise may add to the problem. Making a few adjustments to the recording stage may help in reducing hiss and background noise:

Optimize the Recording Space

The noise-producing items in your recording space may add to the hissing noise in your audio. While most of the noise may seem innocent, they may amplify themselves when listening to the recorded footage. Optimizing your space before you start, such as closing the windows and doors or turning off your electronic devices will help to reduce the noise.

Reduce Subject-to-Microphone Distance

Keeping the microphone as close as possible to the subject will drastically improve the speech-to-noise ratio. The microphone will record more of the subject’s voice than the background noise, giving you a clearer audio output.

Use a Microphone with Gain-Boost

An enhanced gain microphone preamp helps to reduce hiss and notice from the audio in an incredible way. Specifically, the camera’s preamplifier does not add gain because the volume setting is kept low.

Use Directional Microphones

Usually, microphones signal outside their axis. This is often the case for cardioid polar and short gun patterns. This quality is great for reducing noise when you use directional microphones. The microphone will only focus on what you are interested in, ignoring the background noise.

Turn Off Camera’s Auto-Gain

The AGC or Auto Gain Control feature is popular in modern cameras. It automatically adjusts the gain for low- and high-volume sounds to make them even. However, it can enhance everything for a quiet setting, causing hissing background noise. Turning the feature off gives you more control over what sounds to focus on.

Reduce the Number of Open Microphones

Open microphones will continue recording audio even when you are not interested in that sound. Keeping this number low will help reduce hissing sound by focusing only on what you are recording.

Conclusion

Hiss and reverb background noise is an annoying problem. The unwanted sounds affect the quality of your audio and the level of engagement in your footage. While eliminating causes of hiss when recording is the best way to reduce it, sometimes you may notice when it is too late. Using the right editing software will help you reduce the noise and improve the quality of your audio. Wondershare Filmora allows you to do this with the AI Audio Denoise feature. The AI-powered feature will automatically reduce hiss noise and reverb in your clips, giving you clearer and more engaging audio.
