To create an audio spectrum in Adobe After Effects, follow these steps:
Create a new composition with the aspect ratio you need depending
on the destination (YouTube, Instagram, TikTok, etc.). Import your audio file
with the music or sound you want to generate the audio visualizer and drag the
audio to the timeline.
Step
2: Import Your Audio
Open After Effects and
create a new composition (set the resolution and duration based on your
preference).
Import your audio file
by going to File > Import > File.
Drag the audio file
into the timeline.
Step
3: Add a Solid Layer
Go to Layer >
New > Solid and name it "Audio Spectrum."
Set the color to black
or any background color you prefer, and click OK.
Step
4: Add the Audio Spectrum
With the solid layer
selected, go to Effects > Generate > Audio Spectrum.
In the Effect Controls
panel, set the Audio Layer to the audio file you imported. This will
allow the spectrum to react to your audio.
Step
5: Customize the Spectrum
Start and End
Points: Adjust these to set the
length and position of the spectrum.
Frequency Bands: Increase this to add more detail to the
spectrum.
Maximum Height: Change this value to control the height of the
bars.
Audio Duration: Adjust to refine how the spectrum reacts over
time.
Colors: Customize the Inside and Outside Color
to give the spectrum your desired look.
