| In a player piano, a position sensor is provided on an end portion of a lifting rail for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer. A conversion section converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted, into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information. | ||||||

The methods use Bayesian modeling techniques, in which an optimal metrical grid is inferred by identifying the metrical grid that best explains the given sequence of notes by maximizing the posterior probability that it represents the note sequence. Prior musical input from a given user as well as explicit information about the musical style of the input may be used to improve the accuracy of the transcription. | ||||||

| A signal processing apparatus subjects an audio signal to musical pitch analysis using different analysis techniques for the higher and lower frequencies. When an audio signal is input, a first extractor extracts a high-frequency signal, and a second extractor extracts a low-frequency signal from the audio signal. A high-frequency processor extracts pitch components from the high-frequency signal by applying the short-time Fourier transform. A low-frequency processor extracts pitch components from the low-frequency signal by dividing the low-frequency signal into a plurality of octave components. A synthesizing unit then combines the pitch components thus extracted from the high-frequency signal and the low-frequency signal and outputs the analysis result. | ||||||
