How to smooth audio bass bumps for animation
Hi, I am struggling with the smoothing audio keyframes.
Let me describe step by step what I’ve done:
1. Imported the audio file
2. Converted it to keyframes (without any plugins)
3. Created a null object layer for extracting a specific range of values with the following expression
audioLev= thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")
minAudio = 30;
maxAudio = 40;
maxStretch = 100;
linear(audioLev, minAudio, maxAudio, 0, maxStretch);
4. Use this Slider in other layers for animating properties like that
eff_value =110- thisComp.layer("HighFilteredAudio").effect("Slider Control")("Slider").smooth(1.2,9)%5;
[eff_value,eff_value]For example, this video has a nice and smooth logo animation https://www.youtube.com/watch?v=dfzz9-PLmc8
But in my case, I got really sharp bumps, like saw teeth. I’ve played with the smooth parameters dozens of times, but didn’t get the desired result it still flickering.
Here is a chart of the scale animation
I want to get a smooth animation without sharp verticles, something like moving average or other methods. To get something like that
Please suggest how can I achieve this in after effects?
P.S. I am using scripts so it would be better to find “scripting compatible” solution.Thanks a lot

Hey Sergei, one of the simplest ways to achieve what you are looking for – apply effects from ‘Audio’ section before converting audio to keyframes. This will help you to get going.
On a different end, if you are familiar with scripting, then I guess it would be possible to process the signal in more advanced and direct ways, especially if external libraries are to be considered.
Cheers.
