So, I've spent the past two days (and a bit) learning about Matlab GUI and developing a simple (but useful) GUI application for the onset detection and note separation. I'm pretty happy with the results, bearing in mind this is still the alpha version and it needs to be tried and tested.
Here are a few graphics:
Time plot for Double Bass E1B1
Post-processed onset plot for Double Bass E1B1 with cutoff boundaries for the extracted notes:
I still need to add parameter options for smoothing and threshold. These parameters are currently set to constant in the application.
