Sound visualisations

[bencodrington]

It's been suggested that Phanary include some way of visualizing some kind of waveform to easily see where in a loop specifically you currently are. I can see this as being useful especially with some of the suspenseful or dramatic ambiences and songs to allow DM's to time and pace their expositions and plot twists.
I do think it might be kind of complex and resource-intensive to implement, so I'm tagging it as 'future' for now, but any input as to how it might be more easily achieved would be much appreciated!
