// title: SuperCollider sending data to Processing
// author: Luigi Tamagnini
// description:
// first in SC  i analyse audio data with some useful UGens: Onsets, SendTrig and SendPeakRMS;
// this data is then polled back to de client and dispatched to Processing via NetAddr and OSCFunc classes
// in Processing i receive the incoming messages and simple trig a draw function with the callback oscEvent (use oscP5 and netP5 libs
// code:
// Tracking audio data
