Onset Detection Method in Piano Music: Sensibility to Threshold Levels
Piano music transcription requires an stage of onset detection. Every time a new note or chord is played, a new analysis is needed. It is a critical issue to correctly detect if a new note or chord has been played. Onset detection should have a simple solution, but several problems arise when attempting to perform it. This paper present an study of the sensibility of a detection method depending on the adjustable parameters. It also compares some results with a simpler method based on the analysis of the derivative of the energy envelope. The methods have been tested with six piano compositions. As a conclusion, accurate automatic onset detection in piano music is not a simple task.
