The [macronaut] hub_

English net-artist Toxi has released the new version of the hub, an audio visualization software for creating realtime generated and sound-reactive 3d visuals. The engine itself is the successor of the already impressive macronaut.

"The underlying engine does attempt a beat detection instead of visualizing the raw audio data, like iTunes does for example. this extra layer acts as "server" of sorts, providing event data and statistics of a sound fragment to the currently active visual module, which is then free to interpret this data in any possible way. those generated "beat" events are the primary source of change for the visuals. the audio data itself is (so far) only used as additional, secondary input for creating the visuals. as all of the implemented visuals are making use of 3d so far, i also focussed on "filmic" elements like camera changes and cuts as event receivers."
