Help? Audio Waveform

I can't really describe my issue so I'll do my best.
I know AVIUTL is meant for AMV's, recording, voicing, ETC. But I' trying something different.

This is my video here v.v




Notice how the audio waveform bounces up and down rapidly when bass hits (Give it until 0:50)

This is kind of the outcome I want. (Or, close to it)

(Not the logo moving, just the waveforms and how they only react to bass, not the vocals or every beat
Also, how they don't also have a seziure as well, when theres bass it's constant audio waveform all the way up (if it made sense)
When the beat drops instead of how in my video the waveform has a seziure, in the second video it doesn't do that.

Any help I'm grateful for.

Try taking the original audio, and applying a low-pass filter, to cut out all the high frequencies. Then make the audio visualizer with the edited audio. It'll only be picking up on the bass, then.

I'll try that, thank you. ;D

Right, got that part done,
do you think anything can be done about the waveform, like not go up and down so fast?
