I know how to make it a circle make the bars extrude further out ETC but how do I make them "bars" like all mine have rounded edges and they aren't very thick so how would I make them look thicker and not have rounded edges?
I'm not sure how they did that, but here's how I do that:
Solid layer > Effect > Audio Spectrum
choose the audio layer.
Make sure the start point and end point go from edge to edge.
Add a mask over the entire lower half of the image.
Add an Adjustment layer > Effect > Polar Coordinates: set interpolation to 100% and type of conversion to Rect to Polar.
Thickness is its own value -- and you'll find plenty of stuff to tweak.
