Extracting performance data from great piano performances : filtering and formatting of data

As piano recordings on analog form degrade, they are being converted to digital format, one of them being the MIDI format. Such conversion requires an analysis on the recordings that can extract the information needed for a MIDI file, pitch or note being one of the information. Wavelet Transform has...
