Welcome to techyV.com channel,
your solution providers. I am Ben and in this video, I will be showing
you how to make a Visual Equalizer synced with an audio file in Adobe After Effects.
First of all, create a new Comp, drag your audio file into your project tab and then
drag it into your timeline. Create a new Solid. Go to the Effect – Generate
and generate an Audio Spectrum. Now, first of all, you see these two points. This is the start point and this is the end
point of our spectrum. Drag these along your screen so that they
fit at the sides of your screen. Now, see this Effects tab.
Before we start, you need to learn few things. Audio layer:
Basically, we select the track on which we want the spectrum.
So here, I want this spectrum on my track so I have selected it.
If I have many other tracks and I want it on a different track, then I would definitely
select that. Going down, we see the starting frequency.
These are the audio frequencies at which this spectrum will start and the frequencies at
which it will end. By default, these frequencies are the audible
frequencies by humans. These are the frequency bands
either you can increase it or decrease it. Increasing the frequency band means that you will see more bands on your screen which means that more lines and decreasing it means that
you will be going to see less number of bands. Each line is considered as a band.
This is the maximum height. This tells that at which maximum height, our
particular band can touch. So you have to vary it.
Other than that, there are few important things. That is the Audio Offset.
You must keep it to zero. This means that the audio spectrum would differ from our audio
file by which particular number of seconds. This is the thickness of our bands and this
is the softness. These are the colors, you can change them.
You can select any colors you like. Now, going down you see Hue Interpolation.
Hue Interpolation means that the mixing of colors. You should vary the angle. You will see that the colors are changing. Observe the screen as I am rotating the style. So as you see that now we have a spectrum
of colors in our audio spectrum visual equalizer. In display options, we have 3 kinds of displays.
Either digital lines which you are seeing right now or the analog lines which is a bar
and it vibrates on the audio frequency or the dots. We can mix all three of them to create great visual effects. This is Side Options. Side Options means that on Side A, the views
will be generated in the upward direction. Side B means, that they will be generated
in the download direction. So, let’s duplicate these layers and create
a beautiful visual equalizer. Select your main Solid and press ctrl+d.
It will duplicate the layer. Now go to the first layer and you can select
any one of them according to your choice. Go to the second layer and you can choose
Analog lines. Now you will see that for the bottom side,
I have chosen the analog lines and for the upside, I have chosen digital lines.
Let’s duplicate this layer and here, I will choose analog dots and side A and B.
And for this layer, I am increasing the maximum height which means that the dots will leave
these lines and they will go to their greater height. Let’s play it and see how it looks like. Test recording for Visual Equalizer.
Test recording for Visual Equalizer. You can make it look more interesting.
Select all 3 layers. Hold shift and select all these 3. Right-click and choose Pre-Compose. Click OK. Now, you have all these audio spectrums in your Pre-Comp. Hold the shift and drag it along your screen to the half almost. Now press ctrl+d again to make a copy. Go to Transform Properties and rotate it at
180 degrees. Now hold your shift again and drag it back.
Now you will see that we have 2 different types of audio spectrums which are basically
the same but in opposite directions. So let’s replay it and see how it looks like.
Test recording for Visual Equalizer. Test recording for Visual Equalizer.
Test recording for Visual Equalizer. So that’s how you create audio spectrums.
You can create various different effects by changing the hues, by changing the colors
and by making different layers upon layers and adding different effects.
