First of all, you’re gonna need an Adobe After Effects software which you can get it from official Adobe website. Click here to buy the software though you can also use it for a free trial. If you have Adobe After Effects and good PC then you are ready to create reactive audio spectrum waveform effects. So in Abobe After Effects CC you will learn to create audio spectrum and waveforms that reacts to sound generally created with music.

Let’s go to Composition menu and open up a new composition. For HD formats use 1920 by 1080 black compositions. Your gonna need a music audio file so drag the file into the project. So dragged on the timeline and now create a new solid. So go to the Layer to New to Solid. That’s the place to create the waveform onto so by default you should have dark gray solid. Click Effects then head over to Generate; there are actually two options that could play around. One of them is Audio spectrum which is going to give us more of that graph and spectrum type of look. Another is Audio waveform which is more like a zigzaggy waveform. So for this topic, we use audio spectrum and create a video.

The first thing we want to do when we generate the line is you notice there’s no movement. So we have to go over the effect controls for the dark gray solid and the first thing you want to do is set which audio track you want it to react. Drag that audio layer in the composition you can see reacting to the sound of that music. However, the default setting is basic and boring so here you will learn how other controls work and make it stylized and customize it a bit. So the start and end point is basically the start and end of the line. Leave it as a straight line.

You also have the option to set it on a custom path so if you go over to your pen tool, for example, draw out whatever you wanted. You could make it a line to that path and see mask one you will see that the waveform is now on that custom shaped path.

That was one of the option to do it but for now, delete that mask and check out some of the other things to do. So the starting frequency and adding frequency is going to consider what sound range is in the music or audio file to consider to display. Basically, the starting frequency is zero and that’s the left side and the end frequency is how high-pitched you wanted to consider so you see it’s kind of considered like zooming in or out.

The more you zoom in you see the closer it gets the higher frequency you consider the more it zooms out and things kind of get pushed over because your song /audio might not even include all these frequencies. So you want to find a range that fits the nice amount of waveforms in between. Use just about 1 to 1000and you could play around it for your audio files.

Next, we have is Amount of frequency bands that we want to use so the lines and now the default is 64 but if we raise that up you can create lot more bands eventually making it completely solid which can also look cool and we can also lower it so that they’re more spaced out just like some dots. That’s up to your preference and the maximum height is probably one the most important. We can increase the maximum height so you can set a lot more visible jumpiness.

Audio Duration in milliseconds which also considers how much to display so the shorter in you get the more movement you’re going to get but the more duration you want to display its kind of going to look less synchronized. Next, you have an audio offset which is if you wanted to have a delay between the music, for some reason we can leave it as it is to be synchronized perfectly. So leave it at Zero. Thickness is how thick you want those bars to be so you can see thicker not as thick also up to you. Everything depends upon you, the numbers you choose and changes you made.

Softness which you can see as thicker it starts to get all fuzzy looking. You can turn the softness down or up, it’s up to your preference. One can choose inside and outside color of choice. It also has hue interpolation so right now it’s at zero but if we wheel this up you can see it starts to introduce different colors.

In the display options so you can have digital, analog lines and analog dots. For Side options, you can have either the symmetrical side A and B, You can do just side a for that classic equalizer look or you could do side B only for the kind of like a reverse equalizer.

Start to make it look nice balancing between the positive and negative space between these lines. You can also apply effects on top of them to go over to the transitions effects and you can find one called Venetian blinds. What it does when you drag it on is it allows you to adjust the transition completion to have a bit of a blinds opening and closing effect.

If you want to create a ring which you often see like ring audio spectrum head to the Distort Effects and add polar coordinate displacement onto the solid layer. Set it to rectangular to polar change the interpolation to 100% and now if we go back up to our audio spectrum we can play around the start and end points so that things meet up more properly. There are tons of ways you can customize this and play around with it. You can now experiment with the setting and learn from it.
