PROBLEM TO BE SOLVED: To achieve a sound source position display device which makes the position of each sound source, changing in time series, quite obvious.SOLUTION: A CPU 10 acquires the localization information pan from the power spectra of L channel and R channel, obtained by performing frequency analysis (fast Fourier transformation) of the acoustic waveform data of L channel and R channel, and displays the work spectra, having display colors differentiated depending on the localization information pan thus acquired, on a screen in the time series order from the head to the tail of a melody, thus making the position of each sound source, changing in time series, quite obvious. |
