I was curious to know which algorithm(stepwise) is used by the mironsets function of the MIRToolbox library to find the onsets in the audio signal. I am talking about the default functionality when we use mironsets.
Example: o = mironsets('audio.wav')
Here o is the output onset strength envelope and looks like this
There are some questions like - Where is the negative part of the signal gone? Why not all local maximas are considered as onsets?
