flute recording: And a corresponding computer pitch transcription (see Godsill and Davy, ICASSP 2002 ): This is a relatively simple task for single instruments playing one note at a time. We are concerned with the more challenging case of several or many notes playing simultaneously. We will wish to answer some or all of the following questions:
- How many notes are playing at a given time?
- What are their pitches?
- What instruments are playing, and what timbre are they using?
