audio node for the geometry node editor.

I'd love to see a new sound node that has an output socket for volume and another for frequency/pitch. This would be much more flexible than the current sound to samples option in the graph editor, because you'd be able to do things like seperate frequencies without needing to create multiple fcurves for each. Quite importantly this would allow me to easily recreate the frog song: youtu.be/gVfaf43W9cM

It could also have frame start option to specify which frame the clip should begin.
