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.
