AB  - We describe a new method for the estimation of multiple pitch information in recorded piano music. The method works in the time-domain and makes use of a self-generating database of all possible notes. First, we show how accurate polyphonic pitch detection can be achieved given an adequate database. Then an algorithm is proposed that generates the database from the music, using estimation of predominant pitches in the frequency-domain and pitch-shifting techniques. Both systems generate a MIDI representation of the original signal. This method -that can be generalized to any solo instrument- overcomes the usual constraints of the traditional frequency-domain approach regarding intervals and quantity of notes.
