“Chromebook Users’ Companion to Launching and Deleting Audacity”

Audacity has emerged as one of the greatest free audio editing tools for Mac, Linux, & Windows operating systems. With a wide range of capabilities and quality attributes, it is a basic and straightforward audio editing application. While Audacity for Chromebook and Chrome OS isn’t supported, does it imply you won’t be utilizing them in the future? Not at all.

A few simple steps are all that is needed to have Audacity for Chromebook installed on your Chromebook. First, let’s have a look at some of the features this device has to offer.

Features of Audacity for Chromebook

Audacity offers a wide range of editing features right inside its user-friendly interface, and it won’t hold back when it comes to personalization even if it costs nothing. Because it has built-in dithering and is superbly compatible with 32-bit/384kHz audio, it’s difficult to ignore this really effective open-source utility. Importing & mixing audio files is a breeze using Audacity, allowing you to combine stereo, mono, and even multitrack recordings. However, it’s worth noting that there are now just a few possibilities for the latter.

In addition, Audacity for Chromebook has low system requirements, to the point where it works even if your PC is able to power on. Using this editing program, you may mix and match multiple audio formats and sample rates to create a single, cohesive piece of work. In addition, when it comes to editing, you’ll enjoy the unparalleled ease of cutting, copying, and pasting, trimming to the sample level, duplicating, and even adding bespoke fades with the discretely introduced envelope tool.

Audacity seems to have all of the essential impacts. Whether you’re looking for preset EQ curves like those found on a telephone or an AM radio, or Bass and Treble improvements, this versatile program has you covered. With the Auto-Duck tool, you may add a voiceover and other essential features to a podcast, such as a compressor, limiter reverb, and phaser reverb. It’s an excellent choice if you don’t have a lot of extra requirements. Even if you don’t use it often, Audacity will be the last piece of editing software you ever buy.

Installing Audacity for Chromebook

Apps for Chromebooks are often downloaded through the Google Play Store approach. However, sinceAudacity for Chromebook does not support our low-power systems, we must go the other route. To put it another way, you’ll have to use Linux to get Audacity.

Linux is pre-installed on most Chromebooks, however, it is still in Beta. Go to the Settings menu and choose Enable from the drop-down menu to use this feature. Please go here for further information on how to enable Linux on your Chromebook. If your device has this wonderful function, you may follow the instructions below to properly install Audacity for Chromebook.

Open the Linux Terminal in the Launcher.

This is what you’ll see when you click on the Terminal.

To begin installing Audacity, enter the following command in the Terminal window that has already opened.

If you’ve done everything correctly up to this point, you’ll be able to enjoy the full benefits of the Linux operating system. What follows instead is a bewildering cacophony of bluster.

It seems that Linux is questioning whether or not you wish to proceed. To respond, use the “y” key on your keyboard.

This screenshot shows how the installation process is progressing.

Finally, you’ll notice the green-colored text at the finish of the orders. Your program has been successfully installed, as shown by this message.

It’s only a matter of selecting Audacity from the Launcher.

How to Uninstall Audacity

Just like installing it, Audacity can be uninstalled with a few clicks. For this, execute the command below in the Linux Terminal (and you can copy & paste it).

sudo apt remove audacity

When this is done on Linux, you’ll be asked whether you want to proceed with the uninstalling procedure or not. If you hit “y” the same way as previously, Audacity will be removed from your Chromebook in a matter of seconds.

A screenshot of Audacity in operation is here.

While recording your podcast using the built-in microphone on your Chromebook is a great way to start, it’s not the only way to fine-tune the final product. You must drag the track and sound to the center of the screen in order to begin the magic with this program. Once you’ve done this, you’ll be offered a variety of alternatives to get the editing process started.

Using Audacity for multitrack recording & editing is doable, but it’s best to use non-linear tools if primary focus is on that element. Apart from that, Audacity is widely regarded as one of the best audio editors on the market.

Conclusion

Your Chromebook may be able to run a variety of audio recording applications. As with Audacity, you won’t be limited in your ability to produce high-quality music with a wide range of unique effects. We also go through Filmora’s voice effects & how users may use them to change and improve their voices. Filmora allows you to re-voice video/audio & previously recorded voiceovers. For video/audio & voiceover files, the Pitch option on the Timeline may be used. Change the tone of a video and recording to make it sound different. You can quickly alter the voices in the videos using Filmora. Your viral should be accompanied by a story or a video. Using the Changing Pitch option, you may change the pitch of your voice. You may modify the pace of the video to change your voice (Optional). Make a duplicate of the video or audio that has been altered.

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!

So, we decided to keep you informed about how to do that, as well. Wondershare Filmora X is something that can help us with that – it can change our damaged scene into something more acceptable.
