So the post in off topic about G-Force got me thinking and I went back to check out R4 (
http://www.rabidhamster.org/R4/) It embeds perfectly and is an easy way to do some kick-*** visualizations.
Out of the documentation: "To use a PC-based player like Windows Media Player, Sonique or WinAMP, make sure that either 'Record Master', 'Mixer' or 'Wave' is selected, and the Volume is set above halfway (different sound cards have different names - if in doubt, experiment)."
Mine ended up being called Wave Out Mix and it worked best when at full volume.
I attached a screenshot of Centrafuse and the volume control for reference.
