Sometimes footage may sound “noisy” simply because there were too many background sounds when you were recording it. Don’t rush to hit the “Delete” button, though. In most cases, you can easily fix it.

In this instruction, we’ll show you how to reduce audio noise from your recording using VSDC Free Video Editor. If you don’t have the tool yet, you can download it from the official page.

VSDC Free Video Editor provides two powerful Audio Denoise filters: Median filter and Audio gate.

Audio gate is one of the most commonly used techniques in audio production post-processing. This filter comes in especially handy when you work with live recordings trying to remove the unwanted sounds between passages, because it is so efficient at recognizing steady noise sources – such as rumble, hiss, and hum – and reducing them to the minimum.

Technically, when you apply Audio gating, you control when and to what degree audio passes through a channel. In other words, you create a gate to filter the sounds in the video.

You may want to apply gating for three reasons:

1. To reduce the unwanted external sounds
2. To reduce some natural channel noise
3. To use Audio gate as a special effect

Here is how it works. Gates are controlled by setting several parameters:

• Threshold. Decibel level in which the gate opens or closes. The higher the threshold, the louder the sound (stronger the signal) must be to open the gate.

  

• Attack. Controls the speed of the gate opening and consider very fast attack time for percussive instruments. Slower times (10 ms or more) for everything else.

  

• Release. The release time is key to a natural sounding audio decay. For noise elimination with an electric guitar, set the parameter much higher.

  

• Reduction. Sets the amount of signal reduction.

  

• Ratio. It determines how much compression is applied. For example, if the ratio is set to 4:1, every 4dB of signal that crosses the threshold will be compressed down to 1dB.

  

• Knee. Determines how the compressor responds once the signal crosses the threshold. A hard knee clamps down right away, while a soft knee causes the compressor to gradually kick in as the signal gets further past the threshold.

  

• Make-up gain. A control that raises the level of the signal, once it has been processed, to the desired level for the next stage of the signal.

  

Now that we’ve walked through the process of applying Audio gate, let’s take a look at how Median filter works.

Median filter helps you eliminate impulse noise in your footage. In a nutshell, this can be ideal for removing unwanted, frequent sharp sounds like clicks and pops.

• FFT block size. FFT (Fast Fourier Transform) is an important measurement method which converts a signal into individual spectral components and thereby provides frequency information about the signal.

  

• Window type. There are several different types of windows used to reduce spectral leakage when performing a Fourier Transform on time data and converting it into the frequency domain.

  

• Overlap mode. The setting determines what percentage of the FFT size block of data points is re-used for the next trace. Overlap processing can be used to provide high resolution in both the frequency and time axis.

  

• Overlap coefficient. High overlap percentages and low FFT block sizes provide the highest time resolution but take longer to process the data file.

  

Hopefully, this was helpful. Even though it may sound (or look) overwhelming, once you start – you’ll see how fast and easy audio noise reduction really is. Now go and try it yourself!

One of the most popular requests on the VSDC YouTube channel has long been an Audio Spectrum Visualizer. It’s a handy tool that helps you animate your soundtrack, and you can use it for lyrics videos, your online radio broadcasts, or any other music-related projects.

Now, it’s been a few years since we added audio spectrum to the VSDC toolset, and here is what you’ll be able to do with it:

• Create a linear audio spectrum
• Create abstract audio visualization
• Create a circular audio spectrum

And since VSDC is a full-featured video editor, you’ll be able to add titles, lyrics, and stylish effects such as raindrops and foggy glass. Plus, there are 500+ terrific presets available for the VSDC audio visualizer. You’ll be able to create a unique music video and customize the animation to your needs.

In this post, you’ll find a guide to using VSDC audio spectrum visualizer and creating your first sound animation. Stay tuned!

How to use audio spectrum visualizer in VSDC

To create a basic audio spectrum, follow the steps below.

1. Import your file to VSDC. It can be a video file with a sound or a separate audio file.
2. On the left-hand side toolbar, find the Audio visualization icon and make a click on it (see the illustration below). Then select Spectrum.
3. Now, do you want to visualize the audio track of your video file? If so, just close the explorer window that will pop up once you choose the Spectrum. You would use it if you wanted to visualize an external soundtrack located on your PC. We’ll get to that later.
4. In the next window, you’ll be asked about the object position. Decide if you want the spectrum to appear from the beginning of the video or from the cursor position (if it’s not placed at the start of the video), then click Ok. 
5. Click anywhere on the scene and drag the mouse while keeping the left button pressed to place the audio spectrum on the scene. You can move and resize it at any time.
6. Next, open the Properties Window tab on the right-hand side of the dashboard, scroll down to the Audio objects settings, and select Resources - Object on scene. If you can’t find the Properties window, right-click on the audio spectrum object and select Properties.
7. Finally, in the Audio field located below, choose the file you want to visualize the sound from. For instance, if it’s the sound from the video, the name of the video file will show up in the dropdown menu.

Once you’ve performed these actions, use the Preview button to see how the audio spectrum visualizer will look during the playback. Notice that the default style and colors are already pre-configured. Below, we’ll show you how to turn your audio spectrum into a circle or an abstraction. Plus, we’ll talk about changing the spectrum style and colors.

How to create a circle audio spectrum

Now that you know how to create a basic audio spectrum, let’s add a little twist to it. Say, you want to turn it into a circle. Here is how it’s done:

1. Follow steps 1-7 to create a linear audio spectrum visualizer.
2. Make sure the spectrum object is still selected in the scene and go to the Video effects menu. Select Transformation effects - Distort.
3. In the Properties window, find the dropdown menu titled Type, and select Polar coordinates.

Once you create a circle audio spectrum, you’ll be able to change its size, radius, angle, and more! We suggest watching the video tutorial below to see the available options.

How to change the style and colors of the audio visualizer

To modify the spectrum, whether it’s linear or circular, go back to the Properties window with the audio spectrum settings. If you can’t find it, make a right-click on the spectrum object and select Properties, then follow these steps:

1. Find the Audio spectrum object settings menu.
2. Adjust your spectrum type by choosing between gradient peaks, dashes, lines, and lines with blur.
3. Change the color theme by clicking on the three-dot icon (“…”) or the eyedropper tool in front of each color.
4. Note, you can also change the opacity level by double-clicking on the Start, Middle, and End colors. The lower the opacity level is, the more transparent the audio spectrum will be.
5. Use the Preview button to see how the changes are applied.

How to create an abstraction-style audio visualizer

Apart from the spectrum, there is a second way to visualize a sound wave. It’s called Audio abstraction. To create this object, repeat steps 1-5 from the beginning of this article. The only difference is, when you click the Audio visualization icon from the left-hand side toolbar, you need to choose Audio abstraction. Don’t forget to select the audio source in the Properties window on the right, and then adjust the object size according to your needs.

How to visualize a 3rd-party audio track

So far, we’ve shown you how to visualize the sounds from the uploaded video (or audio) file. However, you might need to animate an audio track from a different file and add that animation to your clip. With VSDC audio visualizer, you can do that, too.

Once you click on the Audio visualization icon and choose the desired option – Spectrum or Audio Abstraction – use the explorer that will pop up to choose the audio on your PC you’d like to visualize. Then place the spectrum box on the scene and extend it to the desired size.

For the spectrum, you can choose the animation type, as described above. For the abstraction, there are hundreds of presets available. To check them out, go to the Properties window and scroll down to the Audio abstraction object settings. You’ll find lots of presets and preset groups as illustrated below.

Now go ahead and try the VSDC free audio visualizer!

So, you got a shaky footage, and now you’re looking for the way to fix it? You’re on the right page then. Watch this guide and read the instruction below to see how to quickly stabilize your video using VSDC Video Editor.

Truth be told, most videos shot on the go without special equipment (camera stabilizer mount) come out shaky – just in a varying degree. That happens when you’re holding a camera and your hands start making sporadic movements, or when it’s attached to a drone or a vehicle so that you’re shooting and moving at the same time. Yes, action camera owners, that is especially relevant for you.

Gladly, there is a way to easily remove jittering and achieve a perfectly stable image in the process of post-production. In fact, the Video Stabilization tool is among the most demanded features of VSDC video editing suite. And if you’re curious about how it works, the secret is in the ability to shift video frames. It allows for excluding the shaky effect while any gaps created in the process are being filled with the information from the previous frames.

In our inbox, we often see questions from users on what the best stabilization settings are. So, we decided to address this in a separate tutorial. Below, you’ll see a guide compiled with help one of our dear users who submitted the parameters that worked best for his footage. After being tested, they appeared to be efficient for most shaky videos, so we’re happy to share the secret setup with you.

The parameters used in this tutorial are 'Shakiness' and 'Smooth zoom'. Here is a step-by-step breakdown of the process:

Open VSDC Video Editor and proceed to ‘Tools’. Select ‘Video stabilization’.

Click ‘Open file’ to add the footage you’re willing to stabilize.

Find ‘Shakiness’ among available settings. This parameter detects how shaky a video is and how quickly your camera changes positions and takes control of these movements. Set the Shakiness rate to the maximum using the arrows.

Once you’ve done that, find the ‘Smooth zoom’ dropdown menu in the upper toolbar. This setting allows you for smoothly zooming in the footage.

Select 'Use the smoothed zoom' as shown on the screenshot below.

After performing these actions, you should get a stabilized video, no matter how shaky the original was. So, if there is nothing else you’d like to change in it, just proceed to the ‘Formats’ tab and choose the most appropriate output format. Remember that in VSDC, you can change export profile settings – format, codec, resolution, quality, width, and height - when necessary. If this is the case, click on the “Edit profile” button at the bottom right corner.

Once you’re done, click on the red ‘Export project’ sign.
