Gravitational Tag Cloud

From Music Hack Day

[edit] Gravitational Tag Cloud

by Philippe Hamel [hamel (dot) phil @ gmail.com]

This demo displays a semantic tag cloud of the music, reacting in real-time. The final results gives some kind of dynamic tag constellation describing whatever song you dare to feed to it.

Maybe I should have called it a "anti-gravity" tag cloud, since the tags interact with gravitational repulsion, proportional to their weight. Anyway...

The back-end runs a signal processing algorithm and a neural network to predict the tags. The graphic interface and physical engine runs with Processing. Finally, the audio and clocking runs in Max/MSP. I used OSC (open sound control) to communicate between the three instances.
