There are a few notable music visualisation works in current times, or rather that I have found in my investigations. SoulWire.co.uk has written a quite nice action-script 3 (flash) based music visualisation engine that works very nicely (nice choice of track to demonstrate it with too.) I like the avenues of animation flash opens up to visualisations and its long developed actionscript does allow a good platform for translating code into visuals, but while I believe a lot of amazing music visualisation can be produced using flash I do think that a more beefy technology would allow a bigger scope, its worth noting though that with the browser as a piece of grey, box software becoming less and less of a reality it is potentially past the times of browsers being restrictive to production, 3d graphics and rendering.

While there are certain advantages to having everything available in a browser (Quake live, 3d product catalog’s etc are all good) I do think it means a convergence between the OS and the browser in years to come, for now however and for my pursuits into full hd music visualisations a more 3D strong platform will be chosen. As well as using flash its also worth citing the example of using just Javascript (and canvas from html5) to provide some quite impressive music visualisations, like this example from nihilogic.dk
