Automatic music transcription supporting different instruments

The automatic music recognition from an audio performance is a key problem and a challenge for coding music in western music notation in the digital world. This problem has been addressed in several manners and suitable results obtained when a single and specific instrument and monophonic music are processed. The aim is the development of a system for the automatic music transcription being able to recognise and cope with different music instruments. Experimental results have shown that for monophonic pieces the recognition is quite viable, while for polyphonic pieces several problems still exist.
