Procedural audio reactive animation

I did some tests with letting Sound Keys control Mir that came out pretty cool.

Procedural audio reactive animation.
Quick test using Trapcode Sound Keys controlling Mir to generate visuals from audio.

In this case, three expressions are used on Mir:
Rotate Y = time*20;
Amplitude = 200+thisComp.layer("SK").effect("Sound Keys")("Output 1");
Frequency = 200+thisComp.layer("SK").effect("Sound Keys")("Output 3");

Where SK is the sound keys layer and Output one is setup to capture bass and Output 3 is setup to capture the high frequencies. An invert effect was manually inserted.
