US 6,856,923 B2 · Method for analyzing music using sounds instruments

Abstract

A method for analyzing digital-sounds using sound-information of instruments and/or score-information is provided. Particularly, sound-information of instruments which were used or which are being used to generate input digital-sounds is used. Alternatively, in addition to the sound-information, score-information which were used or which are being used to generate the input digital-sounds is also used. According to the method, sound-information including pitches and strengths of notes performed on instruments used to generate the input digital-sounds is stored in advance so that monophonic or polyphonic pitches performed on the instruments can be easily analyzed. Since the sound-information of instruments and the score-information are used together, the input digital-sounds can be accurately analyzed and output as quantitative data.

Dependent claims

A method for analyzing digital-sounds using sound-information of musical-instruments, the method comprising the steps of:

(a) generating and storing sound-information of different musical instruments;
(b) selecting the sound-information of the particular instrument to be actually played from among the stored sound-information of different musical-instruments;
(c) receiving digital-sound-signals;
(d) decomposing the digital-sound-signals into frequency-components in units of frames;
(e) comparing the frequency-components of the digital-sound-signals with frequency-components of the selected sound-information of the particular instrument and analyzing the frequency-components of the digital-sound-signals to detect monophonic-pitches-information from the digital-sound-signals;
and
(f) outputting the detected monophonic-pitches-information.
