Title: Device and method for deciding chord and recording medium
Inventor: FUJISHIMA TAKUYA
IPC: G10H1/00
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To accurately and speedily decide a chord from musical sound waveform information. SOLUTION: A chord decision device changes the temporal fragments of the waveform information of an input musical sound into frequency region data (frequency spectrum information) through an FFT process (SM3), cuts frequency data in a specific frequency band (63.5 to 2032 Hz) out of the frequency data, and then folds and superposes the data by octaves (SM4). The octave-length profile which is thus obtained is shifted by the deviation width between of the reference pitch of the input musical sound and the reference pitch of the system to correct the pitch, thereby clarifying the peak in one octave (SM5). Then a chord is determined by pattern matching against the standard chord weighting pattern corresponding to the octave (SM6). The octave- length profile has its peaks clarified by semitones by autocorrelation in the semitones before the pitch correction.
