Onset detection with HMM - Code Up gradation

Detect Onset from song using Hidden Markov Model, Based on 3 features of a sound signal , - frame energy - frame zero crossing - frame pitch Generate a HMM which will detect the onset of the song. Also sample dataset needs to be created with any 3 music of short length. I have the sample code for Onset detection using HMM. But the result are not perfect. You need to update the code and train with dataset so that it gives perfect result
