Automatic music transcription (AMT) aims to extract a musical notation in a form of symbolic data from a recording of a music signal automatically. It encompasses a wide range of tasks in the music signal processing, including note onset detection, pitch estimation, and multi-instrument separation. For a full transcription, by means of the complete conversion from an audio signal to a “piano-roll” representation, two essential data of “onset/offset” and “pitch” should be obtained from both temporal and spectral analysis. In addition, our recent studies have been extended to find new features that imply musical expressions, such as a singing voice and varied playing styles of musical instruments.
