Audio Visualizer

Reworked how frequency data is collected:
- Each volume data is now acculumated into a sample until layer the layer renders
- Max values of each sound frequency is kept until next render. You won't miss a beat even with a low render frequency
More than 2 channels are now supported. Each frequency level is calculated as max value of all channels
Fixed frequency misalignment
Fixed mixed calculations from two different volume data
Optimized processing of volume data
