Onset detection function

Variants

Energy

Energy based onset detection function

This function calculates the local energy of the input spectral frame.

Hfc

High Frequency Content onset detection function

This method computes the High Frequency Content (HFC) of the input spectral frame. The resulting function is efficient at detecting percussive onsets.
