More experimentation in After Effects, this is becoming a weekly thing it seems...
This time a more complex spin on the music visualization as seen in my Livestream Announcement video.
This right here is Trapcode Form generating a particle based on the music, the particle's size, opacity and dispersion are affected by different frequencies of the song.
The effect doesn't scale well to Full HD unfortunately, a lot of noise visible making it look grainy, so I recommend keeping it 'regular' HD if you want to try something similar.

It's also very tough on your system, these 37 seconds took 40 minutes to render. But admittedly I made it needlessly complex.

This or something like it will be seen in future videos, so keep an eye out :)
