The beat tracking algorithm is mainly based on a statistical model which use the energy content of the audio signal.

The first choise to make for the analysis of the audio frame is the window: the one chosen here is a rectangular one 1024 samples large with 0% overlap, to avoid latency problems and because we do not care a specific frequency tracking. The sampling frequency that we are considering is 44100 Hz.

For the choice of a given set of light patterns, we need a bunch of rules which depend on the feature extracted.
