Using an effect (Audio Spectrum), as a mask. [After Effects CC]

I am working on a project related to music, and I am using therefore the Audio Spectrum effect.
1) What I now want to do is use the analog line as a border for a mask. The part underneath the line I want to fill with a color, but above the line must be transparant to see the layers behind it.
See pic for extra explanation. http://nl.tinypic.com/r/2dlnoxu/8
Is this possibel and how do I do it?
2) Also I want to use the effect 2 times in the same shot. Now what I can do is put another audio spectrum into the project and do the same thing. However I want to keep the render time as short as possible and adding another audio spectrum will not enhance this.
So it is possible to sort of duplicate the effect? That is just will look at the first audio spectrum and copy past it somewhere else in the shot.
